Zappa Mexico II improve a lot ...on 8 cpu ..
If i compare with my last test rybka - Zappa , Mexico II gain 39 elo !!!
Competitor come more and more closer to Rybka now ... We will not see no more 200 elo difference between Rybka and his closest competitor .
ZappaI think soon , we will see some chess engine that could beat Rybka 2.3.2 smp
This is pity that now A. Cozzie is 99 % retired
