Neue Partie [D]rn5k/1p2q1p1/pB1pp2p/4p3/4P1Q1/2P3P1/PP3P1P/3R2K1 w - - 0 1 As you can see, Amyan 1.54 [P4 1.8/32 MB hash] first prefers 1.Qh4 but the program later switches to 1.Qf3 also winning a pawn. It is clear that programs rather prefer to win a pawn with 1.Qf3 without weaking the own pawn structure. But in my opinion, 1.Qh4! is nevertheless stronger and more forced since in this variation, Black's e6-pawn becomes weak too.
