Hello,

Quote:
But once again, in the hope that one day it will sink in, ....


Vasik Rajlich has become sort of Jesus Christ in computer chess, Osipov has become sort of Son of Jesus Christ in computer chess and Sergei Markoff is very like St. Peter...If after the appearance of sort of Messiah preaching the Gospel of Bitboards in computer chess and things don't sink in, it never will.

But it is still better that Vincent comes back from retirement as St.George without the Dragon don't an epic make.

So while you might be a bit faster in generating _all_ moves, you won't be as fast generating just captures, and for my program, that happens _far_ more frequently.


I'm not sure your statistic is correct here as my QS nodes is about average 30-40%
