2x silver suite runthru; 2CPU each, 256 MB hash, ponder off. TC 40 moves in 2 minutes/20 in 1 minute, & tbh i forget what the third stage TC is, but it has increments.
tbh i think the match may be slightly biased in favor of rybka because we have 'recommended settings' for xmoves/xminutes time controls...of course most of the games played with them are at least twice this long & at faster speed. but the only changes from default are rybka 4 has NM100/MM150 & ivanhoe has 16MB pawn hash & robbobases.
so far the first set is complete; after 108 games R4 leads +27 =60 -21, for a +19 performance edge. will update upon completion.
