Prior to release 2.0 I tested it thoroughly. Ater 400 games it scored about 10 Elopoints better than without futility and delta pruning. It did very well in Testsuitesthough. Fabien decided against it, since 10 Elopoints were too small to be sure that it helps and since I had only data for very fast blitz and the new history pruning was a clear improvement. I think it is a bit more likely that it helps than that it hurt but the difference will be small (10 Elopoints. Perhaps someone will make a really significant test sometimes? regards Joachim
