All that is required for a draw score is for one side to believe it is better and the other side finds a way to force the score to 0.00 or worse, so that the side that is better will choose 0.00 over -0.01 for example If the evaluation is not stable, this doesn't mean a thing. > >It does not change the fact that when all the moves except 6 are singular the >reduced depth is not more than 6 plies. Your definition of "singular" is meaningless. What is important is what the _program_ thinks is singluar based on the search it does to make that determination. Moves that appear to be singular to a human might not be singular to a search, and vice-versa. > >I do not care if they extend 1 ply for every singular move or 2 plies for one of >them and 0 plies for consecutive move. > > But your analysis of a forced draw, based on a >>0.00 score by a computer, is flawed.

You aren't going to find any program that can do an exhaustive proof that the position is a forced draw no matter what white does. you will find programs that encounter intermediate positions where they believe white is better and can push the draw off beyond the search horizon...
