Historical riddle: could Kramnik have defeated the computer?

by Karsten Müller
5/28/2020 – In November 2006 World Champion Vladimir Kramnik played a match against the computer program Deep Fritz. The venue was the National Art Gallery in Bonn, Germany, the prize fund one million dollars. It was the last big man-vs-machine match. Kramnik lost 2:4 and did not win a single game. But in the very first game he had a favourable endgame. Could he have won? Until today that remains unclear. Can you help GMs Yasser Seirawan and Karsten Müller resolve this question?

The duel between the 30-year old World Champion from Russia and Deep Fritz, was set for six games. Vladimir Kramnik had the chance to win one million US-Dollar. Specifically: he could double his starting fee of US $500,000 by defeating the computer.

The Deep Fritz hardware, a Siemens Fujitsu 1.6 Mhz. core duo machine, was located in an elevator at the back of the stage, which was closed during the games to prevent disturbance to Kramnik because of the cooling fans.

The start of game one, with the first move executed by German Finance Minister Peer Steinbrück, himself a keen chess player. Steinbrück went on to become the chancellor-candidate of the Social Democratic Party in the 2013 federal election. On the right is FIDE President Kirsan Ilyumzhinov.

Could Kramnik have won game one?

Now we come to our question where we seek your analytical help. In the first game Kramnik reached a favorable endgame. I believe that a winning proof can be found, but matters are not completely clear.

The riddle of the endgame of Kramnik vs Deep Fritz The last big man vs machine match Kramnik against Deep Fritz in Bonn 2006. Kramnik did not manage to win a single game and lost 2:4 in the end. But in the first game he had reached an endgame, which seemed to be winning and I still think that it is winning. But to this day it is not completely clear. Can you find a winning proof? 29.Nd5 Bd4 30.a4 Bc5 31.h3 f6 32.f3 Kg6 33.e4 h5 34.g4 hxg4 35.hxg4 fxe4 36.fxe4 Kg5 37.Kf3 Kg6 38.Ke2 Kg5 39.Kd3 Bg1 40.Kc4 Bf2 41.Kb5 Kxg4 42.Nxf6+ Kf3 43.Kc6 Bh4 44.Nd7 Kxe4 45.Kxb6 Be1 46.Kc6 Kf5 47.Nxe5 Kxe5 Of course even if Kramnik was winning and even if he had won this endgame, the machines would have overtaken us mortals sooner or later anyway. But I of course hope that a convincing winning proof can be found so that we humans can at least have some sort of revenge against the silicon giants. ½–½

The second entry on out replay board is the deep analysis by GM Yasser Seirawan from 2016.

You probably know that in our replay boards there are a large number of functions you can use to really appreciate the games. Recently we published a comprehensive tutorial which tells you about all the powerful features and buttons that make the ChessBase's replay one of the best watching experiences around.

One big advantage is that you can start an engine (fan icon) that will help you to analyse. You can get multiple lines of analysis by clicking the + button to the right of the engine analysis window. The "!" key, incidentally, shows you the threat in any position, which is incredibly useful in the case of unclear moves.

There is one more thing you can do. It is a lot of fun, but also a serious challenge: Click on the rook icon below the notation window. This will allow you the play the above position against Fritz, at your level of playing strength (e.g. "Club Player"), right here on the news page. Note that your analysis, in which you can delete, move or promote lines, is stored in the notation as new variations. In the end you will find the game with your analysis in the cloud. So nothing is ever lost.

His books on the endgame - among them "Fundamentals of Chess Endings", co-authored with Frank Lamprecht, that helped to improve Magnus Carlsen's endgame knowledge - and his endgame columns for the ChessCafe website and the ChessBase Magazine helped to establish and to confirm this reputation. Karsten's Fritztrainer DVDs on the endgame are bestsellers. The mathematician with a PhD lives in Hamburg, and for more than 25 years he has been scoring points for the Hamburger Schachklub (HSK) in the Bundesliga.
