But indeed they are *not*. The "problems" (rumors?) you allude to in the post only show that you have *not* understood what bitboards are capable of and how to handle them effciently. You are of course free to criticize Bob's coding style and his design decisions in "Crafty". However, only inexperienced and narrow-minded people draw general conclusions from just a single example (i.e. the source code of "Crafty"). There are many ways to do things differently with bitboards and rotated bitboards than in "Crafty". Overall, your post mainly elaborates on some of Bob's design decisions which you deem non-optimal. The only real disadvantage of bitboards at the moment is the obvious penalty of 64-bit integers on 32-bit CPUs which comes hand in hand with unfortunately limited compilers and programming environments. =Ernst=
