Yes I had a feeling that when it comes down to raw speed this would loose out to incremental changes. It seems unnatural to waste knowledge gained earlier in a game, but there must be items that are worth "remembering"? One just has to be selective when it comes to rediscovering vs. storage cost ...

I'm trying out various published move generators (mostly using cpw as my source). One of the ones I want to try/test/integrate is Obstruction Difference. As it states in the code snippet the masks[64][4] structures need initializing; can anyone supply/point me to code for that (I'm implementing in C ...

Hi all, I've had the idea of using an incremental update of the sides movelists rather than regenerating them from scratch after each makemove. Has this idea been explored, and if so are there references to it, or was it discarded? Either way I'd like to hear other's thoughts on the subject.

The ...

Thanks for your reply. Interesting that they're closely matched, it does mean I could still go without the byte array.

Thanks for your knowledgeable reply.

I'm planning on building a bitboard only move generator, and I'm trying to find the most efficient way to identify the captured piece (when there is one). I've read about move encoding with and without piece information; but either at move generation (and hence move encoding) or during makemove a ...

Hi all,
I'm trying to read as many relevant threads on here as possible and one topic I haven't seen anything on is searching without the make/unmake move combo. What I'm thinking about is that since most search algorithms are implemented in a recursive manner could it not be more efficient (faster ...

Thanks to User923005 and lukasmonk for the links.

lukasmonk: that's a great link with all the images etc. Thanks.

User923005: thanks for your complete code, it's already been useful. BTW have you tested it with perft 5 or 6 => the node count is wrong when I compile as is with VC2013.

Graham....

Thanks for the link.

winglet has a board, can display it on the console window, you can set up a position manually,
or read a FEN string from a file.
Some real chess stuff is about to start: move generation.

Hi all,
So I've just discovered Winglet and it's an excellent learning tool. However, in section ...
