An interesting thread about Rybka 2.3 (should be available on february 12) and his new features, described by Vasik Rajlich. In a few words : stronger, new chess knowledge, better search algorithm, better positional play, bug fixes and an interesting feature called "randomizer" :
Quote : "You can put Rybka into a mode where she will play against herself over and over from the same position without repeating variations - she will systematically explore the space of possibilities in the variation, branching from the previous games at later and later points. It's an effective way to get a Monte-Carlo-based evaluation of a position."

The new version of the engine seems to be late, and it seems not only authors of chess engines are addicted to computerchess :)

More info about Rybka 2.3
The new engine should be a bit stronger than the previous version, Vasik Rajlich ran a blitz match (1' + 1") between Rybka 2.3 and Rybka 2.2n2 and got a result of: +245 =607 -193 (52.5%, +17 Elo).
