----------------------------------
All moves are played by Rebel 9 and Diep while still in book. I checked these
positions on a PII/300 at one minute per move and from the point of view of Diep
in the first move out of book:
Fritz 5 Crafty 14.12 Diep Hiarcs 6
1- -0.50 -0.53 -1.00
2- -0.16 -0.20 -0.84
3- +0.06 -0.20 -1.01
4- 0.00 -0.16 -0.24
5- -1.25 -1.13 -1.16 -1.46
6- -1.06 -1.87 -1.24 -1.48
8- -0.56 -0.45 -0.58
11- -0.63 -0.88 -0.78
12- -0.13 -0.59 -0.44
Lines 6, 7, 9 and 10 are identical, and so are lines 5 and 13.
Lines 5 and 6 are the most favorable to Rebel and the only ones that could be
suspected. Line 5 was played in a game Karklins-Leverett in the Chicago US Open
of 1989. This game ended in a draw. Line 6 was played in the game Hazai-Moehring
of Halle2 1981 and it also ended in a draw. No special computer killer lines
here, although no one would be very happy playing black's side.
Nothing strange about the other lines. Black is slightly down when it leaves
book, but this is not uncommon playing black.
What happened in the games Fritz 5 - Rebel 9 played by the SSDF has nothing to
do with cooked lines. Rebel was unable to save its games and therefore to
"learn", and it fell over and over on the same (not cooked) lines.
