Hello! I've done some testing and thinking and I ask the following question: Why have an UnMakeMove or UndoMove function? When testing with Sharper I found that actually copying the board and then calling DoMove on the new board was faster than using DoMove() / UndoMove() on the same board. My Board size is 376 bytes, and I figure that will cause a copy function to require some 94 copy instruction (on a 32 bit machine), this will of course also require some sort of condition of when to stop copying and so, but I figure this must be a much easier task than doing branches and testing if it was a capture etc. and updating piece lists. Is this a unique case for me? Have anybody else tried it? What is your board size in bytes? Maybe this only works for me because my board is small (although I certainly don't think it is small).
