However, the Deep Junior programmers disagreed. At the press conference after the game, programmers Shay Bushinsky and Amir Ban said that, according to their computer, 25. ... Qa1+, the move Kasparov played, was actually the best move. That move led to a draw, whereas the computer might have had winning chances had Kasparov played 25. ... f4, the programmers said.
Kasparov felt that the move 22. b4 by the computer, winning the exchange, was a losing move. The computer had the wrong idea when it went after material. Instead, it should have continued the king-side attack, the commentators said.
In the final position, Kasparov and the Computer agreed to a draw because of the line 31. Re2 Ne4 32. Rc7+ Kf8 33. Rxe3 Nd2 and now there will be a draw by perpetual check with 34. Rc8+ Kf7 35. Rc7+ Kf8, because Kasparov dare not advance with 35. ... Kf6 because of 36. Re6+ Kf5 37. Rf8 defending the knight on f1 and White is winning.
It is remarkable that the programmers agreed to this draw without playing out this line. These programmers are obviously strong players, as compared to the programmers of Deep Blue six years ago who were essentially non-chess players. Also, the workings of the two programs is vastly different. Deep Blue was simply a brute force adding machine, calculating at 200 million positions per second. Deep Junior only calculates 3 million positions per second, but has a lot of chess-specific knowledge which Deep Blue did not have.
Nobody is placing any bets on the outcome. Kasparov has the advantage now but both sides are still learning. Kasparov could tire. A computer never tires.
Kasparov will be paid $500,000 by FIDE for playing Deep Junior. He can earn an additional $300,000 if he wins the match. The event is sponsored by X3D Technologies Corporation, which makes special 3D glasses useful for watching events such as this chess match. http://www.x3dworld.com
