rating list...strategic openign repertoire

[ozziejoe]

I've added many more games. details of tourni are at bottom. It looks like toga 1.3x4 is an absolute beast in this kinds of positions. spike 1.2 was a little disappointing but it is a strong group, and strelka is probably as strong as shredder 10 single cpu

Interestingly, in two of the standard caro kann lines (see below), the computers just do not seem to be any good at the black side.

When white plays bc4, black only wins 27%
When white plays h4, black only wins 37%

In contrast, based on the huge base tree (chessassistant), humans playing black win 44% (bc4) and 45% (h4) irespectively.

The rbyka 2.2nmp evalutations of the final book position (see below) is: .13 (h4 line; depth 16) and .34 (bc4 line; depth 16). So, based on human and computer analysis, there is nothing that wrong with these positions for black
