Fritz Tries a New Twist and Earns a Draw
in Game 4
After getting outplayed in closed positions Team Fritz, led by program creator Morsch (photo) tried a new line in game four that opened things up. Kramnik still gained an advantage but was unable to realize it. With the 41 move draw the first half of the match ended with a 3-1 lead for the human world champion.
Fritz essayed the Tarrasch Defense against Kramnik's 1.d4. This means an immediate push of the black c-pawn to blast open the position. Black is left with a lonely pawn in the middle of the board, but also gets active pieces, crucial for Fritz. Kramnik again got the queens off the board and then followed known theory to reach a superior endgame. But this endgame was one Fritz understood and it played excellently to split the point. Kramnik will have two days to rest up before the match resumes on Sunday the 13th.
Team Fritz will have to work hard in that time to come up with something to use against Kramnik, who has seemed invincible so far. They must try to keep the queens on the board and to reach position in which Fritz can demonstrate the tactical mastery that its famous for. Until now Kramnik has brilliantly avoided such positions, and game four was no exception.
Of the millions of spectators watching the game transmission live, only a handful would have known that game five followed a known game until past move 20! Kramnik's long-time assistant, Spanish GM Miguel Illescas, had briefed the champ on this line and this knowledge proved valuable as Kramnik played the opening almost as quickly as Fritz. Only on move 22 did Kramnik pause to consider the different paths available for prosecuting his advantage. With a pair of powerful bishops and an active rook, the Grandmasters watching the game thought that white had fair chances for a win.
"Against another GM I think Kramnik would win this most of the time," opined four-time UK champion Julian Hodgson (left) after move 22. "25.Ra6 is a good move, a very good move," this from Grandmaster and London Times columnist Raymond Keene, "Black is going to have a very difficult time in this ending."
And a difficult time it was, until Kramnik surprisingly decided to avoid the most promising line on move 26. Instead of the expected 26.Bd4 the world champion simplified the position with 26.Rxc6. This gained an extra pawn but allowed Fritz to exchange the bishops and reach a position in which it could calculate the draw with near perfection. From that move on the computer evaluation never showed any concern over losing the game. Kramnik pressed on hoping for a Fritz mistake for another 15 moves.
Frederic Friedel of ChessBase said that Sunday's game five was practically a must win situation. Fritz's programmer, Dutchman Frans Morsch, said about game five that "anything can happen. We still have a few arrows in the quiver." He added that as well as avoiding closed positions they now knew they should avoid queen exchanges whenever possible in order to have serious winning chances against Kramnik.
Kramnik leads the match 3-1 with two wins and two draws. All eight games of the match will be played even if Kramnik reaches the needed 4.5 points. Fritz will have the advantage of the white pieces in game five and will have to pull out all the stops. King's Gambit, anyone? At least we don't have to worry about past chess match scandals, like the players kicking each other under the table or accusations of secret messages in yogurt or parapsychologist mercenaries. Compared to those items from human-human matches, playing a computer is perfectly normal!
