To make ma program faster I included Null-Move and a cutoff one ply before the horizon, if the position is "good". On the other hand, simple mates go beyond the horizon (also because of small quiet search). My idea: If I do a Null-Move it Cuts if greater Beta. OK if it is much lower than alpha I extend the search, because it could get to some interesting mate. The idea behind: In Null move the other side can do 2 moves in row. If this gets to a very high score (mate) it is interesting enough to extend. I made some tests, and the program really found the mates 1 to 2 plys faster. Also, the program does not get much slower. Is this a "good idea". Why not use Null-Move the other way round? Comments? Werner
