speed improvement by hashing evaluation components

[Uri Blass]

Movei evaluates every node because it is using the evaluation components later for pruning decisions.

I decided to save time by not calculating them before searching them in the hash tables.

It seems that it gives me 10-20% speed improvement that is not much and I wonder how much speed improvement you get by this idea(of course only programs that evaluate every node for pruning decisions can use that idea).

The main advantage is that changing the program to use that idea helped me to make the program more simple and to discover a bug but I am not sure if fixing the bug is really productive.
