Hi
Thanks Scott & Richard for the replies, I forgot to mention in my post that I
had already implemented killer moves, that did help quite a bit as you say.
Out of interest here is my output for nodes and time for the start position.
What would the concensus be on these figures, good, bad or average ?
I am guessing my nps is good but my nodes visited is fairly bad compared to
typical engines.
I think I will concentrate next on trying to improve move ordering some more
rather than trying futility pruning and other risky sounding stuff. Looks like I
had better have a go at a root search function, but I am not that clear yet on
how to get a better move order at the root.
