I cut off from my program if (height>=level-2 && wrpx<beta && val_gatunek[spr_poz]==UBOUND) { do_null=false; } and for example in place where is code: case LBOUND: if (wrpx>= beta) { if (antr>1) ans_hash[antr].sx=-1; return beta; } now I use code: alpha=max(alpha,wrpx); if (alpha>=beta) { if (antr>1) ans_hash[antr].sx=-1; return alpha; } and my program can find it on depth after 1 minute on Athlon 1700+ It is long time but now my program can do it! :-) Now I have got next problem. Maybe null move in pown ednings it is bad idea? What do you think about it? Are you use null move in pown endings? Do you think that I can have bug in null move prunning? Best Regards and thank you gor all!!! I love you !!!! Now my program can solve 4 position more in WAC!!!! wow! Grzegorz
