I had time to play one game this afternoon. And I am really pleased that I did. This is a lesson on how to confuse and play around with your opponent!
Round 1 Game 1:
DB Fritz 2 - AM68060 Sargon 3
RESULT: 0-1

CRITICAL POSITION
[fen]2b1k2r/1p1pppbp/5n2/rp3p2/1nP5/6P1/P3PPBP/R2QK2R w KQk - 0 14[/fen]
AM68060 Sargon 3 dubiously decided to give up its Queen for a Bishop and two Knights. But it seemed to work well as DB Fritz 2 had no idea on how to proceed after that. In the above position DB Fritz 2 plays 14. Qb3 which was not the best continuation. Better was 14. Qd2.
FINAL POSITION
[fen]6k1/1p1bpp2/1P3b2/2p3p1/5n1K/4pr1P/8/7Q w - - 0 43[/fen]
AM68060 continues with its winning ways and DB Fritz 2 gets checkmated in 42 moves.

I seriously doubt that there are many programs around that would have the temerity to play 11. ... gxf5!? and sacrifice their Queen for 3 minor pieces? ... and then win the game so easily! Amazing really....

Wow, this is bringing back so many memories! The very first computer I bought was in 1995, an old Packard Bell running Windows 95. The first software I bought for it was Chessmaster 4000 Turbo. I had so much fun playing chess on the computer in those days. I would download all the programs for windows I could find. Gnu Chess, Arasan, K-Chess, and all these great old programs. I even bought Kasparov's Gambit, and I loved it because it was so different and quirky.
There used to be a game that came with Windows called Ziggurat. I don't know if it can be found anymore. And there was this TINY little windows chess program called Waxman.
One of my absolute favorite's though, was PowerChess. There was just something wonderful about having that PowerChess Queen analyze your game move-by-move with that sexy voice.

Thanks for spotting it. I may have inadvertently flipped the images when I sized them down to that small size. Anyway it is corrected now. Not intended to fire up the folks from down underjupiter6 wrote:I really enjoy reading your summaries, however I thought you might like to know this:
The Australian flag is upside down, and the New Zealand flag is around the wrong way. It's not a great look.

DB Kasparov Gambit was out of book too early which decided the game before it really ever started. In this position out of book DB Kasparov Gambit plays 10. Nc3? to give DB WChess 1.05 a good advantage and an easy win. However Gambit's position was already bad so there was nothing to play that was much better.

DB Chess System Tal has the better position in this endgame because of the two Rooks on the 7th rank. With good play a draw was still very probable for DB Nimzo Guernica. However DB Nimzo Guernica starts playing inacurately and ends up losing. In the above position DB Nimzo Guernica plays 41. ... Ra4?! Better was 41. ... Rae8.

DB Socrates 3.0 positionally stands better. MAC Sargon 4 should have played 37. ... Bxf4 and make it a Rook and Pawn ending with good drawing chances. MAC Sargon 4 made a mistake playing 37. ... Kh7? which ends up losing.

W3X K-Chess 2.0 already has a slight advantage shortly after both programs left their opening book, when W3X Arasan 2.0 makes a bad mistake playing 16. ... Ng6? which allowed W3X K-Chess 2.0 to play 17. Nd6! which was very strong. Best move in this position was 15. ... Nf5! in order to stop Nd6.
