It uses non-rotated bitboards and so must frequently scan the board for slider move generation and attack detection. So far I like it. It's given me the simplest move generator and make/undo code that I've gotten so far. It is slightly slower generating moves than my 0x88 program, but I suspect/hope that will be offset by gains elsewhere--specifically in the SEE and eval. Name: Shrike Author: Dan Newman -Dan.
