Certainly, the second one is always better than the first one. 5% of not bestmove is too small. It is much smaller than the harms of selecting not good opening lines, play the black side, effects of random numbers/computing, null-move, pruning, etc. If your engine is the second kind, it should be in the top of the world ;-) (It is likely you have the best program with a very small bug). Note that the most important period of a game is middle - around 20-30 moves. 5% is converted into 1-2 moves only (and 5th best moves are usually not fatal mistakes) - I think, this is a desirious number. >On July 10, 2001 at 17:52:04, Fernando Villegas wrote: > >>I do not understand that kind of dilema or clasification.
