Nxh4 Be4? { A misevaluation: f2-f3 is not "provoked" as much as it is "played with tempo" here, giving White's king some "luft" and helping the heavy pieces travel to the kingside if needed. But most importantly, White's exposed g4-pawn would have been a useful target for Black to aim against with a well-timed ... Qd8-d7 in order to bring the rook to the e-file before White could infiltrate with Re1-e7 or Ne1-e7+ (see annotations below). } (22... Bc2 23. Qd2 Bh7 24. Bd3 Bxd3 25. Qxd3 Nd6 26. Nf5 (26. Ng6 Qd7! { This is the (very deep) point: Black had time for a useful tempo move on the g4-pawn, and can swoop over with the rook and trade off one of White's few remaining attackers next move.
