Seems incorrect to me, but I was doing a quick scan. That's a speedup trick. There is no need to check the legality of move if it is being pruned, so I do the pruning test first, then if it fails, I do the legality test. It was good for a speedup of around 5% :) > I'll try profiling it now. Will post the results here. Thanks, Pallav > > Charles
