Re: SEE on non-capture moves in main search

I think the problem is this: with things like hash moves, good captures, killers, etc, by the time you have tried all of those, either you have already failed high, or you are never going to fail high at this position. In the so-called ALL positions, ordering is irrelevant anyway, and wasting comput...

Re: Check idea + bittwiddler request

I had an idea about deternining if a move gives check (the new? part is about discovered check). A move gves check iff 1. a. The piece moved is not a slider and it attacks the opposing king. b. The piece moved is a slider and there is a horizontal, vertical, or diagional line between the to square ...
