I found that movei probably earns from clearing it's hash tables. One of the changes in the latest Movei is telling it to clear it's hash tables between moves except cases of serious time trouble. I do not know why it happens but it happens. I did not expect not clearing the hash tables to change much because I use the always replace method and I use hash tables only for better order of moves but for some reason I found that different order of moves may cause different moves and it seems that not clearing the hash tables cause inferior moves. I found that after 1.b4 Nc6 2.d4 d5 movei0.071a played Bf4 because it's score for Bb2 at depth 8 was -0.37 and it changed it's mind. I found that without the moves movei see at depth 8 score of -0.26 for 3.Bb2 and does not change it's mind at that depth. I believe that 3.Bb2 is a better positional move than 3.Bf4 After this observation I decided to test movei with clearing the hash tables and I simply get better results. I am going later to investigate later the reason for the different scores for 3.Bb2 but IO first interested in the 1...a5 problem and I do not understand the reason that movei starts every match under winboard with 1...a5 when it is supposed to start it with a move that is different from the move that it played in the last game. Movei does not behave like this if I play a game against it exit winboard and play another game with the same color. I need 21 games to get the same reply with black like previous game. Uri
