Jan-05-08  Orion Sphere: And so Fritz came to be.
Jan-30-09  rwbean:

"Fritz played a tricky
transposition in the game against Deep Blue Prototype (DT-2). Normal book line is to play Bg7 before f4. Our game database did contain the transposition, and gave the verdict that o-o or o-o-o is no good in the position, and g3 or c3 is called for. The automatically generated book, unfortunately, cut off right after the early f4, and our luck ran out. Normal book line is Bg7, o-o, f4 and then g3, by the way. This loss is probably good for us in the long run. Book preparation will be taken far more seriously from now on. One additional side note. Instead of c4? allowing Qh5, the immediate g3 appears to hold-- might still be lost against the likes of Kasparov, but I doubt Fritz can push it through. The machine did play g3, but the phone was disconnected at the worst possible time, and when it was restarted, it did not have enough time to rediscover the move." -- Feng-Hsiung Hsu,, 1995-06-05

13.5 years later ... :)

It looks like 14. Kh1 and 14... Rg6 are both mistakes. Rybka 3 suggests 14. c4 (0.00 -- pv 14. c4 bxc4 15. Nxc4 Rg6 16. Nd2 Bg4 17. Qxh7 Rh6 18. Qg8 Rg6) and 14 ... Bg4 (+1.58 -- pv 14 ... Bg4 15. Qxh7 Rg6). 14 ... Bg4 sacrifices the h-pawn and prevents the Queen's retreat to d1, effectively winning.

13. o-o is not the best, but not a losing move -- the real losing move is 16. c4??. After 16. g3, the eval is +0.92 -- pv 16... Rh6 17. c4 Nd4 18. Nc2 bxc4 19. Nxd4 exd4 20. Be2 Bg7 21. Nxf4 d3 22. Bh5 Kf8

Oct-25-09  dannygjk: my Tal personality prefers 11.ef
Oct-25-09  dannygjk: my Tal personality prefers 14.c3
Oct-25-09  dannygjk: my Tal personality prefers 15.Nb5... I'll let that variation play out and report later...
Oct-25-09  dannygjk: 15.Nb5 was a draw eventually with my Tal personality @ 2 minutes/move(ply) on my computer.
Oct-25-09  WhiteRook48: 14 Qxh7!!!
Oct-26-09  dannygjk: If 14.Qh7 Rg6 15.Qh5 Bg4 16.Qh8 Bf3 17.g3 Rh6 18.Qg8 Qc8 with a won game.
Jun-12-12  Patanjali: Whatever the analysis may be, this game has to be the computer chess equivalent of David VS Goliath. It's a real encounter between two machine intelligences that demonstrates the truth that having superior software on inferior hardware is better than having inferior software on superior hardware.
Dec-08-21  rwbean: 13 years later ... SF051221 ... 16. c3 ♖h6 etc ... score -3.00 (40 ply) ... none of f3,g4,g4, or c3 would save White here.

14. h3 ♖g6 ... score -1.29 (35 ply)

so 13. o-o was a big mistake ... 13. o-o-o, g3, or c3 would be even ...
