I thought this combo approach would be a little slower than the traditional single key approach, since you are generating a new key from scratch each time you call your move generator, but I implemented the combo method using 32-bits per key, and it ended up running 9% faster than the traditional 64-bit key, so speed shouldn't be an issue, at least on a 32-bit machine. I still don't have any idea if it will be any more effective. I only hashed the from and to squares for the move list key. I'm not sure if that is sufficient or not.
