FYI, it turns out GWD has been playing with up to the 5-piece EGTBs only during the first four rounds. This leads to considerable evaluation errors of easily a half to a full man if most end-nodes happen to end-up in 6-piece EGTB positions, as the neural network has not been trained on positions with less than 7 pieces. This happened around move 50 during the game against Maximus, so GWD chose the 'best losing move' instead of a drawing move.

You are simply changing options in the program too often and this is causing this problem. Another thing is that you should also make the program with different databases and this should not affect the game.
