My guess is that the result will be similiar at longer time control. I know that Gambittiger has also significant evaluation problems. I saw tournament time control game when GambitTiger could not win against Gandalf inspite of evaluation of 6 pawns advantage. The problem is that GambitTiger did not trade to an endgame because it was too optimistic. Here is the position when Gambit evaluated +6.12 [D]r6k/7p/p2qbp2/4pp1P/r7/P1pB1PP1/2N1R3/2K1R1Q1 b - - 0 1 GambitTiger played 30...Qxd3 (6.12 at depth 11) and after 31.Qb6 could not find 31...Qb5 and prefered 31...Qd7(4.34 at depth 14) and later drew the game. GambitTiger is also a preprocessor and it is another evaluation problem. Uri
