Excuse me, but with replies like that people will start to think that you are a troll. Please don't explain to Uri Blass how engines work: He has written an engine himself. Call it bug, mistake, error or whatever you like: If the shortest possible mate in a position is #14 and an engine displays #11, there is something wrong. Maybe a rare effect of nullmove pruning or something like that... but #11 is simply wrong and not a "better evaluation!" :) Yours truly Paul J. Sacral
