Last day

The King won another spectacular game against Tao in the seventh round of the tournament. The King, the chess engine of the well-known chess program ChessMaster 9000, lost its first game in the tournament in the penultimate round against Fritz. In the same round Shredder beat Diep, which meant that both programs had 6,5 point out of 8 games. But also Deep Sjeng won in the 8th round, this time against The Baron.

Last round

In the last round The King had to play with the black pieces against Chess Tiger and although the French program did not play a good tournament, it it still on of the strongest programs in the world. The King played with a fearless attacking style, so he is a deserved winner of this game and the tournament. “I played with the same version as last year”, De Koning told me after the last game. “I changed only some minor things, I think that it is very difficult to improve the program further. If I start changing things, the program may get weaker”. De Koning does not want to play in the world championship this year in Graz. “No, I don´t want to play there, I want to play Amazons with my program in the Olympiad, take a look at the chess games and relax a bit. A world championship is a lottery. However, I think that my program would play very well there, it is a strong program, of course.” That´s right Johan, and congratulations!

Rounds 3 - 6
The King, a.k.a ChessMaster leads the field after 6 rounds in the 3rd International CSVN Computer Chess Tournament. The program, made by Dutchman Johan de Koning played some fascinating games, culminating in a spectacular queen sacrifice against “Diep” in the sixth round.

In the third round of the International CSVN Tournament in Leiden Shredder and The King could add another victory to end the first day with a 100% score. The other favourites for first place, Fritz and Chess Tiger, only scored 50% on day one. On Saturday, first thing they had to do, was to play each other and it was obvious that it was going to be a very important game. The winner would still have chances to win the tourney. The game ended in a disaster for Fritz after the program was outplayed in the opening. Frans Morsch, author of Fritz, shook his head: “We shouldn’t have played the Najdorf in this game. The game was lost as soon as we came out of the book”. Jeroen Noomen, the Dutch opening wizard, who is responsible for Chess Tiger´s opening book, had found a hole in our Fritz book. Noomen: It was a lucky shot, because Fritz had played this line before in a world championship game against Crafty. I never thought that Fritz would repeat that variation but I decided to give it a try.”

Shredder and The King do not very often play against each other in tournaments. Last year in the CSVN tournament, Shredder won a good game. This year The King showed no fear, although Shredder started a dangerous attack. “I grab all the pawns I can get and wel´ll see what happens”, Johan de Koning smiled during the game. It turned out to be the right strategy against ex-world champion Shredder. The King got a good position with black, but the position was very difficult to evaluate, even for computers. De Koning: “This game is a good example to show that chess still has a lot of secrets. The tactics in this game were very deep and it was impossible to evaluate the position properly.” The game ended in a draw, but this game will be interesting to analyse with different chess programs.

In the fifth round Chess Tiger was lucky to get away with a draw against IsiChess MMX and Shredder saved another very difficult position against Deep Sjeng. The position seemed to be lost but Shredder found a perpetual. The King won against The Baron after a long fight and Johan de Konings brainchild crushed Diep in the sixth round with the black pieces after playing a majestic queen sacrifice.

Rounds 1 - 2
In the first round we saw some fascinating games with surprising results. The Baron, a program made by the tall Dutchman Richard Pijl drew his game with one of the top favourites, Chess Tiger. The biggest upset in the first round, however, was the victory of Deep Sjeng, the Belgian program of Gian-Carlo Pascutto over the well-know program Fritz. The Dutch-German program Fritz had to deal with serious problems in the middlegame after a Nimzo-Indian opening. White´s passed pawn on the b-file proved to be the decisive factor in this game. Shredder and The King played some convincing attacking chess against Tao and Ant. Diep played a long game against SpiderChess and had to be satisfied with a draw in the end.
In the second round we could witness the first tournament game of “Nullmove”, a program made by Richard Langeveld. The young Dutchman, who has been a regular operator for Bob Hyatt´s “Crafty” in world championships, had no chance with his baby against Sjeng. The other programs with a perfect score after two rounds are Shredder and The King. The King, the engine of the ChessMaster programs, played a good game against IsiChess MMX and Shredder had no real problems with XiniX. Two other favourites for first place had to fight hard in their games: Fritz battled it out in a sharp opening against Tao but could not win with the white pieces: the game suddenly ended in a draw. The winner of the CSVN tournament of 2001 and 2002 now only has 0,5 points after two rounds! Chess Tiger, winner of the Dutch Open in 2000, 2001 and 2002 could win after a long battle against SpiderChess.
