Unlike most of the crowd, at all stages I was confident Rybka would not lose this game: http://wwwcs.uni-paderborn.de/~IPCCC/IPCCC2005b/pgn7.html [Event "IPCCC"] [Site "Paderborn"] [Date "2005.12.30"] [Round "7"] [White "Ikarus V0.36FR7a SMP"] [Black "Rybka Beta w64 1.0"] [Result "*"] [ECO "B00"] [TimeControl "7200"] 1. e4 Nc6 2. d4 d5 3. e5 Bf5 4.

Kg2 * [d]r7/1pk5/2pN4/4P3/p4P2/8/2N3KP/8 b - - 0 44 After the obvious 44. ... a3, Ikarus has absolutely no winning chances and would be astoundingly lucky to draw (a power outage, maybe?). I stopped looking. While the above game is very far from a fine example of what Rybka is capable of (it is more of what poor Ikarus was hoodwinked into permitting), I could thank a few of the forum's "chess experts" for the amusing fantasies and wrong prognoses they wrote about this game along the way. Black obtained three supported united passed pawns on the Q-side while the White King was so magnificently placed on h1. Rybka's opponents do not properly know how to handle the very unbalanced positions that arise from Rybka's Tal-like sacs. So the theoretically unsound sac delivers the full point more often than not, until the next generation of opponents evolves. My general evaluation of Rybka: Much stronger than overly-staid Fruit, psychotic Shredder, berserk-monster Fritz. 'Extraordinarily dynamic middlegame: unbelievable Rybka, a killer grandmaster.' A. Steen strongly recommends Rybka - * to patzers, to watch/study it play their other engines, and hopefully learn at least a little therefrom; and * to others, to play it themselves. Congratulations, Mr Rajlich. You clearly have (at least?) one super-GM on your team. :-)
