Hi Perhaps this is something Vas may concern himself with Were you matching the rybka's head to head against each other or against other programs ? If other programs was the same number games played against each opponent ? Were all using same book ? What were the scores & error bars of each program ? Personally blitz does not concern me much but it would be interresting to know Tom
