Well...
I'm just a patzer, but since there are all levels of players here...
My computer is low-end for today's standards, and I use only freeware engines for cost restrains. I used about 4 different engines for analysis during my WC and Class G games, but it proved to do less difference than I expected. I was the weak link at all times in the chain, and only in the games I was able to understand why my engine showed certain moves should be made I was able to win.
But I guess you can't always blame on the patzer. I had quite a few instances that it became obvious why I couldn't understand the moves: the engine was wrong. Best way to test this is to let it run a position where it gives a slight advantage to you for 15 minutes. After that, make the moves and check if you have the same score or better. Of course it might be just my below-average computer, but the shareware version of Fruit got me into some really bad spots. The best solution I had up until now was Toga II, as it proved to be pretty solid on that aspect.
Elmer Valderrama (2006-10-04 22:36:44)
Toga
Since everyone is being honest in this thread here is my confession..
Usually I use latest Toga, I bought Rybka 1.2 series, but I've found it is not better than Toga, especially if run in a slow computer (I still use a AMD +1600, with Windows 98: I know I should buy a better computer but this one is already a recent "upgrade" from a Pentium 700Mhz running Fritz 8 ;) and I dont want to fall in the endless (and costly) chain of keeping -up-to-date just to get a few more ELO points ;)
Sometimes I test the positions with other engines (Fritz 8, Schredder 8, free Fruit) just to prove how right was Toga in the initial evaluation. In those rare but happy occasions when I make my own input is simply to give an idea of where should the engine "think". When things go well, after some point, it is just a matter of setting the engines on my opponents, they would finish the job.

retire, come back. What's next ?
I’m playing in two tournaments with Mr Marez : class M02 and WCH M01. Mr Marez had practically retired from the FICGS tournaments because he did not play for a very long period (one-two month). He lost on time 4 of 5 remaining games in each tournament. Now he comes back to continue the games he did not lose on time. By proceeding like that he is not fair to all the participants in the given tournaments, ruins the results and gives a not serious character, an amateur-like flavor to the tournaments. On top of that he is now registered for other tournaments. I think someone must do something about that.

GNUchess
Lionel, are you sure about GNUchess ? .. seems quite weak to me, did you have a try with Fruit, Rybka 1.0 or Toga ?
About Scrabble, what do you think of my idea (several posts above) to eliminate chance completely ? I'm thinking about a new board (and name for the game) with these rules - letters 'out of bag' and ordered already - may look like a chess-scrabble ?!
Lionel Vidal (2006-12-09 21:24:05)
scrabble+
Your idea for scrabble is interesting but the luck seems still there (not that luck is a problem per se IMO): even if the letters are shown, their very order is luck dependend ; and the only thing that really changes is that you can forsee the letters of your opponent and play accordingly... and so the game is actually more simple (!) IMO, more calculating prone and less strategic because you remove some possibilities, all as likely, in your move tree.
To be more concrete, suppose you can play a scrabble for, say, 75 points, and open the grid for the opponent, or play a nice glue-word for, say 40 points, but let the grid closed enough. In your proposed game, I just have to look at my opponent possibilities, as I know his letters... I calculate one, two or more moves ahead and say, ok, I can open the grid and still win by 10 points. In the normal game, I have to estimate, if the openess of the grid is worth the 35 points difference and that means calculating the rough propabilities to score points on the letters I open, considering what my opponent already played, if he seems waiting for some specific letters, or maybe he is bluffing, but then by experience I know that the double 'e' I let is not very valuable, considering that only four expensive letters remain...and so on: the game seems much more strategic and interesting for me.
Of course, I can loose because my letters are really bad... but that is quite uncommon on a whole game for good players, and almost meaningless on a match with, say, five set or more. (remember that the goal is not to make words, but to score points, or to prevent your opponent doing so on the grid, something a good player can almost always do whatever his letters).
For the chess engine, I did try some, and frankly my level in blitz play is so terrible that gnuchess is enough for me for a quick match:-). Now I tried Fruit and Hiarcs on some of my correspondence games and even on my modest scale, I was not very happy with the result: they did suggest others moves than mine, but that were moves I would never have played (maybe (surely?) I am wrong, but I am not sure)... so what would be the point to waste computer time? Even if they may suggest a good move I missed, I would still feel uneasy to play something 'outside' my own mind... old fashion maybe, but that is how I have fun in chess :-) I still like the waiting of the reply, while wondering if I made an oversight! (that being said, I used and will still use the tablebases reading engine when needed: very useful at some points :-)
But then maybe my biais against engines made me use them badly :-) Never mind, I am not going to apologize for that to a silicon piece of junk :-) And if the beast feels somehow insulted and asks for a real time match, let's just play Go!
Thibault de Vassal (2006-12-14 00:09:56)
Rybka clearly the best engine vs. engine
I fully agree with both of you... We must be careful, even if all these results are really impressive, most chess engines have been designed to play against humans and to be useful analysis tools. As I said in another thread, there are still many things to improve to make it the best engine vs. engine fighter.
Nowadays, the best chess engines try to 'think' like humans and actually have inherited human weaknesses from them, so IMO a Hydra or Deep Blue would crush ie. Shredder or Junior which try to make it harder for human brain while Fritz is clearly better balanced.
Maybe this new engines generation started with Fruit which plays very solid. So Rybka, which is clearly designed to beat his rivals but I'm not convinced at all it is a better tool to play correspondence chess.
Daniel De Noose (2006-12-13 14:29:26)
Rybka clearly the best ?
This week I have tested Rybka againt 3 others engines.
The parameters :
----------------
Intel Centrino 725 (1,67 Ghz), 64 Mb Hash Tables, games in 10 minutes (+ 2 seconds per move) for each "player", Shredder 9 interface, 20 games' matches, HS-Masterbook Opening book .
The Engines :
-------------
Rybka 2.2 W32, Gambit Fruit 1.0 Beta 4bx, Toga 1.2.1a and Shredder 9.
The Results :
-------------
1) Rybka - Shredder 9 :
15,5 / 4,5 (+13,-2,=5)
2) Rybka - Toga 1.2.1a :
12 / 8 (+8,-4,=8)
3) Rybka - Gambit Fruit :
13,5 / 6,5 (+10,-3,=7)
The comments :
--------------
Rybka seems to be clearly the best for the moment ... I would like to test Rybka against other engines like Fritz 10, Shredder 10, ... but I don't have these engines. Perhaps later... ;-)
Do you have comments about this ?

Rybka, Fritz and future...
Computerchess is definitely an exciting challenge... The community is fast-growing, new versions of chess engines appear every day, many dream to be the next Vasik Rajlich and to produce an engine that would beat the well-known Chessbase engines and the famous Rybka.
These days, I had a look at Fruit 2.1, TogaII and Crafty source code that are available to download, and started to implement new search & evaluation functions. It's quite easy to understand why chess programming is so addictive, so much done and so much to do... finally I did not enter this mad race without an ending, probably for the same reasons Anthony Cozzie (the author of Zap! Chess Zanzibar) and many others retired.
However here are my feelings about future of chess engines, and the fight that just started between most probably Chessbase engines (Fritz, Shredder, Junior and Hiarcs) and a new era of chess engines that started with Rybka...
First, it's quite obvious to me that Rybka (now Rybka 2.3) is only another one of a long series of chess engines always stronger than each others ! .. I expect the next ones to reach 50, 100 then 200 points more (and maybe more) on the next chess engines elo rating lists, a scale that definitely can't be compared to human elo rating list ! .. Several reasons to this : (1) Chess engines are human killers at standard time controls, but chess engines are far to play perfect chess yet. (2) The way ratings are calculated.
Rybka taught us several things IMO :
- Algorithms and evaluation functions are no more enough. Now chess engines have to play chess, not only search a tree of chess positions... That's probably what Rybka brought to computerchess. Since Fruit 2.1 & Toga II source code is available, and computerchess community is constantly discussing improvements in algorithms, evaluations of positions and new ideas, to implement a chess engine becomes easier so I have no doubt that new very strong chess engines like Rybka will come.
- To become famous, a chess engine must 'also' beat his rivals. I first thought that Rybka was designed to be an engines killer only (at least before to be an analysis tool) with some tricks exploiting most engines weaknesses. No, Rybka is also a great UCI engine, simply stronger and with many options & features. Like Vasik Rajlich, who is engineer and international chess master, you'll have not only to think like an engineer to create such an engine. However I still don't think it is the best analysis tool for correspondence chess, it doesn't play really better chess and in all cases it is not enough. More, Rybka 3, 4, 5 shouldn't influence correspondence chess (maybe even human vs. machine) much... Computerchess influences computerchess first.
It's written sometimes that the strongest chess engines could reach a IM, even GM level at correspondence chess. I definitely disagree with that, at least for the moment (it will take a long time yet), but as chess engines results tend to approach correspondence chess ones (means more and more draws), I do think chess engines have much to learn from correspondence chess players way of thinking, meaning : A more psychological approach, bonus for traps detection. Evaluate moves, not only positions. A more complex search, not 'only' iterative (brute force is definitely useless). No more anti-human style, speculative moves (=weakness, ie. Deep Junior) for speculative results against strongest chess engines, draws are prefered. To avoid positions not understood by the engine. Longer games, closed games (if supported)... Opening books should look like correspondence chess GMs ones (of course according to the engine's style of play) and no more been made of FIDE GM games. A better time management... Future of computerGo may teach to computerchess about some evaluations.
A chess engine must play good moves AND try to win (which is not always the same). It seems Fruit & Rybka play solid and are waiting to exploit their opponent's weaknesses thanks to a better "chess" algorithm/knowledge. As far as I have seen, Shredder & Fritz still have the best 'eye', they see far but fuzzy. Quite the same about Fruit & Toga developped by a great engineer, Fabien Letouzey : Less chess knowledge but an improved algorithm. As for Rybka, a great chess knowledge and probably a smarter algorithm (not better, smarter !) were probably enough already. The future best chess engines will be made by good chess players...
An interesting point is it could be not so easy, maybe even nonsense, to create the best analysis tool that would also obtain the best results against other chess engines. My first prediction is Rybka won't be the top rated chess engine ever, hundreds of new ideas will appear in all parts of chess programming, slowly breaking Rybka secrets, then speed will be a factor again. Deep Fritz, Junior, Fruit or Hydra are most probably the core of the next generations of chess engines... but there's a lot of work yet :)
My two cents.

Les échecs en France
Here is the agreement just signed by the ministry of education and the french chess federation - fédération française des échecs (F.F.E.)
This should help to promote chess in France.
CONVENTION-CADRE
Établie entre les soussignés :
L'État - Ministère de l'Education nationale, de l'Enseignement supérieur et de la Recherche représenté par Monsieur Gilles de Robien, ministre, ci-dessous dénommé " le Ministère "
et
La Fédération française des échecs représenté par Monsieur Jean-Claude Moingt, président, ci-dessous dénommé " la Fédération "
Rappelant
Que le jeu d'échecs, activité à la fois ludique et sportive, constitue aussi et surtout une activité intellectuelle qui permet de développer des compétences diverses chez ceux qui le pratiquent, et notamment chez les jeunes auprès de qui il constitue un réel vecteur de formation ;
Que la pratique des échecs encourage notamment le développement des capacités intellectuelles telles que la mémoire, le raisonnement logique, la capacité d'abstraction, l'analyse de problème et la mise en oeuvre de stratégies de résolution ;
Que la pratique des échecs contribue également à la construction de la personnalité en encourageant l'attention, l'imagination, l'anticipation, le jugement et la confiance en soi ;
Que le jeu d'échecs, école de concentration et de maîtrise de la pensée, est enfin une école de maîtrise de soi qui favorise l'apprentissage des règles et le respect d'autrui, et à ce titre participe de l'apprentissage de la citoyenneté ;
Considérant
Que, pour toutes ces raisons, le jeu d'échecs constitue un complément légitime et pertinent des activités éducatives proposées par l'Ecole ;
Que de nombreuses expériences menées en académies ont permis de mettre en oeuvre des projets de qualité associant des établissements scolaires et des clubs d'échecs dans un cadre réfléchi et concerté entre les parties concernées ;
Que ces initiatives ont permis de développer des pratiques et des outils permettant une exploitation du jeu d'échecs dans un cadre scolaire et/ou périscolaire ;
Il a été convenu ce qui suit :
Article 1 - Objectifs
Par la présente convention le Ministère et la Fédération affirment leur volonté commune de favoriser le développement de la pratique du jeu d'échecs dans les écoles, les collèges et les lycées. Ils se donnent comme objectifs la mise en oeuvre de deux axes de travail privilégiés :
- le jeu d'échecs au service de l'égalité des chances, l'expérience montrant que la pratique des échecs peut constituer pour des élèves en difficulté scolaire une occasion privilégiée de se remotiver et de se remettre sur la voie de la réussite scolaire ;
- la dimension éducative du jeu d'échecs auprès du plus grand nombre, en favorisant la transférabilité des acquis entre les pratiques ludiques et les situations d'apprentissage.
Article 2 - Egalité des chances
Le Ministère et la Fédération conviennent de développer l'accès de la pratique des échecs auprès des publics scolaires qui en sont les plus éloignés pour des raisons sociales ou géographiques. Le partenariat portera en particulier sur des actions impliquant :
- les collèges " ambition réussite ", qui visent à offrir un cadre d'excellence à des publics scolaires confrontés aux plus grandes difficultés socio-économiques. La contribution de la Fédération consistera notamment en mise à disposition de matériel (ludique et/ou pédagogique), en actions de sensibilisation ou de formation organisées dans le cadre des établissements concernés, en appariements des collèges avec des clubs de proximité ou encore en parrainage de certains collèges par des joueurs de haut niveau recommandés par la Fédération.
- l'opération " Ecole ouverte ", qui accueille les jeunes dans les EPLE pendant les vacances scolaires pour leur proposer des activités de loisirs à visée éducative. Parce qu'il conjugue les dimensions ludique et formatrice, le jeu d'échecs correspond bien à l'esprit de ce dispositif qui contribue à modifier l'image de l'école auprès des jeunes.
- les dispositifs relais (classes et ateliers), qui accueillent temporairement des élèves en voie de décrochage ou de désocialisation. La pratique des échecs peut permettre à ces jeunes de reprendre goût à l'activité intellectuelle, tout en leur inculquant le respect des règles et de l'autre.
Article 3 - Action éducative
De façon plus générale, le Ministère et la Fédération conviennent d'encourager la connaissance et la pratique des échecs auprès du plus grand nombre. A ce titre, ils pourront notamment :
- développer la pratique des échecs dans le cadre des activités péri-scolaires au sein des internats scolaires, des clubs et des foyers socio-éducatifs, en partenariat avec les clubs locaux.
- mettre en place des actions de sensibilisation et/ou de formation dans les écoles et les établissements volontaires, en rapprochant les équipes éducatives et les clubs selon des modalités à préciser entre les partenaires concernés : enseignement et pratique dans le temps scolaire ou périscolaire, projets thématiques fédérateurs s'appuyant sur les dispositifs transversaux, opérations d'information et d'animation, tournois scolaires à l'échelle d'une ville ou d'un bassin, etc.
- développer des ressources en co-édition, en lien avec le réseau des CRDP et des CDDP (sites Internet de jeu pour les écoles, dépliants de présentation, outils pédagogiques, etc.).
Article 4 - Contribution des partenaires
La Fédération française des échecs s'engage à apporter aux écoles, collèges et lycées qui en font la demande une aide en matériel ou en ressources diverses (publications, outils pédagogiques etc.). Dans le cas d'actions spécifiques conduites au sein des établissements dans les temps scolaire ou périscolaire, les cadres qualifiés de la Fédération ou de ses organes déconcentrés devront avoir reçu un accord préalable du Ministère et/ou de ses services déconcentrés ; ils pourront apporter des aides techniques ponctuelles auprès des enseignants qui en feront la demande après avoir pris l'avis des corps d'inspection.
De son côté, le Ministère s'engage à diffuser, par le biais de son réseau de communication et de diffusion ainsi que par l'intermédiaire de ses services déconcentrés, l'information nécessaire à la mise en oeuvre de ce partenariat.
Article 5 - Communication
L'application du présent accord-cadre peut donner lieu à des déclarations et communications aux médias par chacun des partenaires, lesquels conviennent de se concerter préalablement.
Article 6 - Mise en oeuvre et suivi
Les partenaires conviennent de se réunir au moins une fois par an pour examiner les conditions de mise en œuvre de l'accord-cadre et dresser un état des lieux des actions entreprises sur la période de l'année écoulée.
Article 7 - Durée
La présente convention est signée pour une durée de trois ans à compter de la date de la signature. A l'issue de ces trois années un bilan global permettra de faire le point sur l'évolution des pratiques à l'école, au collège et au lycée et d'étudier sur cette base les termes du renouvellement de la convention. Elle peut être résiliée par l'une ou l'autre des parties, à l'expiration d'un délai de trois mois suivant l'envoi d'une lettre recommandée avec accusé de réception valant mise en demeure.

Rybka tops SSDF rating list
2007 april 21 - New SSDF computer chess rating list is out !
http://web.telia.com/~u85924109/ssdf/list.htm
Rybka 2.3.1 tops the list with 2962 elo, followed by a surprising Hiarcs 11.1 with 2871 elo. Then, Junior 10.1 and Fruit 2.2.1 followed by Shredder 10. That's a pity Fritz 10 and probably Zap! chess Zanzibar are not rated yet.
The king Rybka will probably have serious opponents soon...

chess engines
Couldn't you have waited until our game is over before buying Rybka? lol! Fruit 2.3 is the strongest free UCI engine that I know of.
Thibault de Vassal (2007-09-10 22:42:32)
chess engines
First of all, every chess engines is a choice, ie. about selectivity, and has consequences & weaknesses in particular positions. Fruit/Toga algorithm is really good but it has probably still much less chess knowledge than Rybka. I think Rybka's algorithm is really better also, Vasik Rajlich added some "human features" while other programs still think about chess like mathematics.
Rybka changed correspondence chess because Fritz or Junior (very strong chess machines) added to a good chess player makes a good centaur while Rybka is "almost" a centaur itself... Consequently a weak chess player can reach quite easily a 2100/2200 rating. That's the main reason...
Of course Rybka will always make some bad moves, but it/she builds an advantage move after move against other engines in most cases in 'calm' positions. HIARCS, that was told during a long time to think most like a human, was not a strong 'chess machine'. I don't know much about Hiarcs 11/12, but Rybka is a major improvement in this way IMO.
Andrew Stephenson (2007-09-10 23:31:53)
chess engines
Hi Jason As Thibault post indicates Toga is a fruit flavour ie fruit variant. Check CEGT rating list for single version engines (http://www.husvankempen.de/nunn/rating.htm) Toga II is at no3 and Fruit 2.3 is at no 5 position. As for our game no engine is ever going to save me! Maybe 28 ..Rc8 would have held but earlier on 14 exd6 Bf6 15 Bxf8 Kxf6 16 Qf3 looks really disgusting for black. I am not going to blame the opening but Fritz and I are back to the Najdorf! Apparently Aagard had a book out on offbeat sicilianl ines in which he could find no way for white to gain an advantage in this Prins line hmm Im sceptical. Thibault - thanks for expanding on your comments. I note your point about calm positions. The game I cited is the sort of wild position where Rybka is not so good later in the game it is convinced that 19 ..Nxf2 is good for black a move which loses and which fritz rejects fairly quickly.
Thibault de Vassal (2007-10-20 05:17:30)
Rybka 3, Fritz 11, Shredder 11...
Rybka 3, Fritz 11, Shredder 11, also Chessmaster 11... new versions of many engines are announced or coming (Fritz 11 - end of november).
It is said in computer chess forums that one secret of Rybka may be "table of exchanges", in other words knowledge, added to a 'simple' & very fast engine typically like Fruit. Many now think that other engines may catch Rybka in a while, but we might have to wait for the thirteen series at least IMO :)
Anyway, the battle continues... Also waiting for Hiarcs 12 !
Edwin Dabbaghyan (2007-10-20 11:14:42)
where?
Hello everyone...just got back from a 3 drunk days cruise trip and am quite beatable ;)....where exactly do we play the freestyle? on a server client or on this website like any other game? Hej, William, Eros and Alberto...good luck friends:)
Thibault de Vassal (2007-11-03 05:26:32)
Free engines to download
I see that Fruit 2.3.x and Toga II 1.3.x series (and of course Rybka 1.0) are still the best free chess engines to download, quite near Chessbase engines strength.
Shredder 11 seems to be sold with Fritz 10 interface and old 2007 chess games database, a good reason to buy forthcoming Fritz 11 ;) .. I assume that Chessbase will focus on the interface and Chessbase 11 (or.. 10, 12 ?! hard to follow)
Which is the current best free engine to help in correspondence chess games in your opinion ?
Philip Roe (2007-11-11 19:16:42)
cui bono?
Thibault,
I'm not at all clear what your proposal is intended to achieve.
Are you trying to save us from ourselves? Ruined careers, failed marriages, social withdrawal, vitamin deficiency...? If so I can't imagine a one-size-fits-all solution.
Or are you protecting other players from the phenomenon of a player who takes on a large number of games and then, for whatever reason, forfeits many of them? This seems to happen regrettably often and for that purpose it seems perfectly reasonable to ask people to qualify before managing a large number of games. Can you pull any statistics that might be revealing?
Thibault de Vassal (2008-05-19 21:54:37)
Fritz 12, Shredder 12, Junior 12

Poker at FICGS
I've never heard of poker having an elo rating system. There is too much of a luck factor in order for that to be meaningful IMO. Obviously there is some skill in poker, but the fruits of this only manifest in the "long-run". Even top professionals have had losing periods in excess of a year in duration.

Poker
"I should have said my statement was about those who know the mechanics of the game"
Actually, you've just confirmed that you don't know anything at all about the game of poker. As is the case for you with chess. And you obviously didn't understand the expression "-EV" , so I'll explain it to you. EV means expected value. It is the sum of the probability of each possible outcome of the event multiplied by the outcome value (or payoff). Thus, it represents the average amount one "expects" as the outcome of the random trial when identical odds are repeated many times. Obviously if this value is a negative number, money-management is completely meaningless as you will lose money in the long run. Money management is actually the easiest thing to figure out. It's a no-brainer for anyone who knows anything about money gaming. It has to do with ensuring that you have enough cash on hand to keep the risk of ruin down to a comfortable level, to account for standard deviation (bad luck). If you're a losing poker player, ie, one in which the net result of all your decisions results in a negative expected value, money management is clearly totally meaningless. This simple concept is quite obvious to most people. I've never before met an adult who required it to be explained to them like this.
People who's minds go beyond the superficial understand that there is much more to poker than working out the simple arithmetic of the game, such as how many outs for a flush/straight.... pot odds, implied pot odds, etc, which is probably what you mean by "knowing the mechanics of the game". Playing that kind of mindless, one-dimensional game might work OK at microlimits, but beyond that you'll need to learn that poker is much more of a game of psychology than it is a game of math. A mathematician by the name of Barry Greenstein, who incidentally has won more than $10,000,000 playing poker, once said that also. I've got a feeling he knows a bit more about the game than you do, lol.

Fire on board...
Open letter by Gata Kamsky :
"Dear President, gentelmen, Susan,
When I first saw Bill's letter I was happy, because finally USCF has been showing strong support for their representative. Whether there could be a better solution or a more diplomatic one is a good question, but the reality is that there is no time to negotiate and given FIDE's strong-arm history of negotiating, it is not likely to succeed.
When I spoke with FIDE Vice President Mr. Makropoulos in Greece, it was decided that both my team and Mr. Topalov's team would meet during the rest day at the Olympiad in Dresden to negotiate and discuss everything, including technical details. With their last public statement, Mr. Illumjinov not only attempted to revoke his personal guarantee of the match, but he also imposed the time limit of one week for the players to acceed to his demands and at the same time re-awarded the bid to the Bulgarian Federation, which was the original FIDE's intention in the first place. You all are aware of the clause in the FIDE regulation for this "special" match that gave the Bulgarian Chess Federation a privilege of matching any bid that is coming from my side, which effectively ruined any attempt to find and submit a bid from the United States.
Throughout the negotiations with my managers, FIDE did nothing to find a sponsor on their own, despite the fact that it was solely FIDE's decision to create this match, and thus to allow Mr. Topalov a backdoor into the final steps of the qualification proceedings for the world championship title, quite unfairly, I might add.
FIDE's entire purpose, for chess players, for fairness, has been changed into a special interest group organization and I personally believe that any negotiations with FIDE rulers or tsars, or whatever you like to call them, will be unsuccessful.
The time for the negotiation is over and the only way to fight FIDE is to expose their mistakes, and perhaps fight them in a court of law if and when FIDE broke the law. Therefore, I would respectfully request all USCF Board members to unite and find ways to make sure that justice and fairness will prevail.
Sincerely,
Gata Kamsky
Saturday, November 8, 2008"

You are abused by a mediocre clone
http://en.wikipedia.org/wiki/Hydra_(chess)
The machine described there relies on a 64 PCs cluster, each PC being equipped with specially designed FPGA hardware cards for chess processing.
So there is no sense in asking "do you use the hydra engine?" : the hydra engine proper won't run on anything else than its dedicated hardware.
At the time Hydra had just beaten a few GMs, there appeared a so-called Hydra engine in dubious sites. This was soon proven to be a mere clone of the Fruit engine, completely unrelated with the true Hydra machine.
This is what you may still find on sites like the TommyThomas one.

The King's Indian Defence is a chess opening that begins 1.d4 Nf6 2.c4 g6 followed by ...Bg7 and ...d6. The King's Indian is a "hypermodern" opening, where Black lets White take the center with the view to later ruining White's "wonderful" position, often by an attack on White's king. It is a risky opening, which has been a favourite of players such as former world champions Garry Kasparov, Bobby Fischer and Tigran Petrosian. Prominent grandmasters John Nunn, Svetozar Gligoric, Wolfgang Uhlmann, and Larry Christiansen have also played this opening frequently.
According to Chessbase, black chances are about 42%
