I suspect that you can find every best move by defining the right personality. It proves nothing. The point is that as far as I know no playing program can find Bh3. >The Nolot position No.11 it has a lot more problems with finding the best move! I guess that by changing parameters you can solve nolot number 11 in less than 1 seconds. It is possible that Q5T is not the right personality for this position. Uri
