Fred de la Foret (2019-02-23 20:12:55) Best Opening Move? The English ( 1. c4 ) is considered less popular as best opening move to 1. Nf3, though the English is played by many OTB Masters. Normajean Yates (2008-12-17 18:05:42) anyway, about the 16-queens mate-in-4: Svante Carl von Erichsen showed it was possible to solve without computer help: http://www.ficgs.com/user_page.php?page=problem_read&id=311 As for proof game, The foll is from my rec.games.chess.analysis post [it *was* .analysis I think - feeling too tired to search usenet] " This one is mine: 1. 4k3/qqqqqqqq/8/8/8/8/QQQQQQQQ/4K3 w - - 0 109: [pos. 1] White to play and mate in 4. There are no duals - only one moves mates in 4. [there is no mate in 3 or less.] Move given at end of post, with sample continuation. These two were posed by me and solved by likesforests [see fics (www.freechess.org) or chess.com] in 20 minutes total! 2. Give a proof game for pos. 1, ie Show that the position in prob. 1 is legally reachable by giving a game that leads to the position. 3. Okay, so you can reach a position where you have 16 queens on board. Can you construct a game which reaches a position with 18 queens? If so, do so! [the last part carries 99% of the credit - it is to pre-empt the answers "yes" and "no". ----------------------------------------------------------------------------------------------------------- (note: these can be more conveniently viewed at chess.com in the thread "advantage of moving first - mate in 4 in symmetrical position" in the forum-category "more puzzles") ------------------------------------------------------------------------------------------------------------ Solution to 2: by likesforests [Event ] [Site ] [Date ..] [White likesforests] [Black likesforests] [Result 1-0] 1. a4 b5 2. a5 b4 3. a6 Bb7 4. axb7 Nc6 5.

Thibault de Vassal (2407) c4 The English Opening is the fourth most popular opening move in chess. White begins the fight for the center by staking a claim to the d5 square. Common responses are 1...e5 (which can lead to positions similar to the Sicilian Defence but with opposite colors), 1...c5 (the Symmetrical Variation), and 1...Nf6. Also perfectly playable are 1...e6 (often leading to a Queen's Gambit Declined after 2.d4 d5) and 1...c6 (often leading to a Slav Defence after 2.d4 d5, a Caro-Kann Defence after 2.e4 d5, or a Reti Opening after 2.Nf3 d5 3.b3). The English is a very flexible opening. Although many lines of the English have a distinct character, it often transposes into other openings. If White plays an early d4, the game will usually transpose into either the Queen's Gambit or an Indian defence. The English derives its name from the English (unofficial) world champion, Howard Staunton, who played it during his 1843 match with Amant. It fell out of favor (the opening was notably disdained by Morphy), but is now recognized as a solid opening that may be used to reach both classical and hypermodern positions. Botvinnik, Karpov, and Kasparov all employed it during their world championship matches. Bobby Fischer created a stir when he switched to it from the King's Pawn against Boris Spassky in 1972. ============ Contributors : Thibault de Vassal
