[D]4qr2/4p2k/1p2P1pP/5P2/1P3P2/6Q1/8/3B1K2 w - - 0 1 The solution of this study is Ba4 b5 fxg6+ Fruit2.2 default can see high score at depth 18 with the right solution Fruit2.2 Uri cannot see it even at depth 19(it can see Ba4 b5 Bc2 as the main line) At 120/40 Fruit2.2 default can play the right moves Fruit2.2 Uri cannot find 2.fxg6+ when it gets depth 18 in a game when it already got depth 18 for 1.Ba4 Fruit2.2 Uri has no problem to find high score for 2.fxg6 with clear hash at depth 15 It seems that without clear hash 2.fxg6 is not in the pv so it is pruned by Fruit2.2 Uri when with clear hash it has not the same problem. I thought that history pruning=70 means less accuracy at the same depth relative to history pruning=50 but I am even not sure about it after analyzing this study. Uri
