Wilhelm 1.49 has played pretty well in this Tournament. Here in this position, the game looks drawish. The Crazy Bishop however makes a few slightly weaker moves in this endgame and Wilhelm 1.49 takes full advantage.

Wilhelm 1.49
Wilhelm 1.49 was written by Rafael B. Andrist (Germany) in 2005. It is a Windows chess program and it has quite a few interesting configurable options. The FEN Generator is also quite nice.
Match 2: Crafty 18.12 vs. Comet B62 DOS
Playing White pieces, Comet B62 won the first game, taking full advantage of the two pawns it had gained in the middlegame.
In the second game it is Crafty's turn to take advantage of some wrong pawn advance choices made by Comet B62:

Comet B62's position here looks quite solid. But, Comet now advances the wrong pawn. 15. ... c5! would have been a much better move. Comet continues to advance Black's pawns throughout the game and Crafty takes full advantage of the weakened pawn structure.

Match 3: Pepito 1.59 vs. Bringer 1.9
Pepito 1.59 won both games very easily and gives TEAM: Classic Engine - 2 a 4 : 2 lead. I thought at this stage that Classic Engine - 2 might now get going and win the match comfortably.

Yace 099.56 made a mistake here. This allows Nova Chess 1.12 to open up the f-column and puts lots of pressure on Black's King.

Yace 099.56 managed to get back into the game and for a few moves it seemed that a draw was still possible. But after 59. ... Rc4?? Nova Chess 1.12 gratefully takes advantage of this last mistake!

Yace 099.56 has been playing pretty well in this tournament; therefore this defeat was quite a surprise!
Yace 099.56 played the next game much better and tied the encounter 1-1. The match score is now 5 : 3 in favor of TEAM: Classic Engine - 2.
Match 5: Alex 201 vs. Chess Fiz 016
In the first game Chess Fiz 016 makes mistakes shortly after the opening book finished in a Sicilian Najdorf and gets checkmated in 39 moves giving TEAM: Classic Engine - 2 a 6 : 3 lead. In the next game it is the turn of Alex 201 to make lots of mistakes and to lose the game.
Match 6: Gromit 3.1 vs. Ychess 1.09
With a 6 - 4 lead and the way Gromit 3.1 has been playing, I would have bet my house on TEAM: Classic Engine - 2 finishing with a score of 8 : 4. But chess can be unpredictable sometimes and in these two games Ychess totally outplays Gromit 3.1:

Already after 13 moves the position for Ychess 1.09 looks quite good. But, the next move from Gromit 3,1 is really bad since it loses a piece. 13. ... Qc8 might have been better to protect the black Bishop on a6.

Final score of the Match between TEAM: Classic Engine - 2 and TEAM: Dos/Windows - 2 - Germany/Austria 6 : 6 !!!!
Match between TEAM: Atari ST - 16 Bit and TEAM: Neo Classic Engine - 1
9.1/2 - 2.1/2 is the big win that TEAM: Neo Classic Engine - 1 needed in order to give the team a good chance of winning Group B. However sometimes the final scores do not show or give justice to the hard fought encounters. Team: Atari ST should have played the match a lot closer as the following examples will show:

Gnuchess 3.1 won both games against BBChess 1.3b giving Team: Atari ST a great start to this match. Both games were completely dominated by Gnuchess 3.1. Here is one of the games:

With 5 points from the first 8 games, I did expect Psion Chess to at least get something from this match. In the first game The Baron 2.23 completely outplayed it's opponent. The second game was a lot closer:

The position looks good for at least a draw for Psion Chess. Leading by a pawn. But the position is complicated and Psion Chess starts to lose ideas and slowly allows The Baron 2.23 to take over.

27. ... Nb4! looks very good for Chess Player 2150. But it does not see the move and instead plays 27. ... h6?? turning the game completely upside down.

Here is another example where the Atari Program has the better position and has played quite well up to this point. But once again when the position becomes critical the program misses the best and obvious (for humans) move. In this position 33. Nb6 or 33. Nc3 would have been good with advantage for White. 33. Rce1? loses the game. At 30 seconds most of the programs do not get to search the full 5 ply and therefore seem to miss some critical continuations.

Hermann 2.5 just made horrible mistake with 47. Kxd5? He should have taken with the Rook which although should still lose, it would at least make it a lot harder for the opponent. But, typically for Atari ST

Check Mate misses the most obvious move 47. ... Rd7!! which would have easily won the game and instead plays 47. ... Rb4 and ends up losing. Incredible!!

Here is an interesting position. Check Mate has slowly thrown away this game but perhaps still has one final chance for a draw. It needs to play 49. Kxh5! instead of the played move 49. Kxf5? I am not sure if Kxh5! draws, but I think it does.

I have shown more games then I really intended, but I think these examples will show that TEAM Atari St was not bad in this Tournament. It just lacked some depth in critical postions.
Match between TEAM: Modern Engine - 5 Amateur and TEAM: Saitek/SciSys - Switzerland
In order to become Group B Champions, TEAM: Saitek/SciSys - Switzerland needed to get 8 points from this match.
But unfortunately they could not get the necessary amount of points needed. The encounters against TEAM: Modern Engine - 5 Amateur were extremely competitive and the result could have gone in favor of either Team. The Final Score of 6 : 6 was a fair result for both Teams. Both played some great games.
SciSys Turbostar 432
SciSys Turbostar 432 was another dedicated computer whose program was written by Julio Kaplan and came out in 1984. Running at just 4 MHz, the Turbostar 432 is another fine example of what a good program was capable of achieving at low speed.
The Turbostar had a pretty good tournament, but it met its match in this encounter against Scorpio 2.3. Scorpio 2.3 won both games, but they were quite entertaining. Here is one of the games:

In this interesting position, Turbostar 432 has the better pieces, but the black King is trapped and the Rook can't do much other than hold White's advanced Pawn on E7. Scorpio 2.3 has a stranglehold on Black's position and leisurely wins the game.
