You are not making yourself clear. Before you said: >>> it's pitty that most of the chess programs are fast BITBOARD based and not >>> selective search programs. I then replied >> I suspect that only a small minority of programs are bitboard-based. Now you are talking about "bit-operations". If you mean 64-bit bitboards, where each bit represents some condition about a particular square of the board, then my statement is probably true. If you mean "the majority of programs use 64 bit numbers (eg for hash tables)", then of course that is true, but what possible relationship does that have with selective search? Andrew
