Hi friends, My chess engine currently has two search related problems. 1) Sometime a e.g. 8 ply search only returns a pv a say 4 or 5 or sometimes even only one move. Can this be a result of using the hashtable? 2) The engine searches until a certain amount of time is spend. If the search notices that the time has ran out, the search is stopped an beta is returned. I think this is the correct thing to do. BUT the following happens: sometimes a 8 or 9 ply search is done and a correct move (at least a correct move in the eye of my engine) is found but then suddenly a completely different move is selected, most of the cases this is a blunder and often the evaluation drops with about the score of a bishop because a bishop is lost. It is nice to have written a enging playing like a human, but i would rather remove this problem. Any suggestions where to look for? thanks in advance Jan Willem
