Hi tord what does gothmog selectivity 6 means? My guess is you do null_move for first 6 plies and static eval pruning for the rest. I mean is it like Ed's? I saw in gothmog's ini an option to turn off null move. Well does that mean selectivity 0 , which does only static eval pruning for the whole of the iteration depth. I have added static selectivity pruning in DanChess. This is the first time i disabled the null move code in search of other methods . Guess what it is not that bad! It takes around 330000 nodes to reach Depth 9 at the initial position for both methods. True,the static method sometimes make clear mistakes at positions where positional score dominates. The static method is only at embroic stage and that is expected any way. since you are more experienced than me in these method,i am hoping you will help me with ideas. best daniel
