Qa4 {Diagram [#] This is an interesting moment in the game: white played the opening moves without some concrete idea and black easily equalized the game. Still the player with the white pieces decides here to play on, only because he is higher rated (2283 vs 1959) but the position objectively doesn't allow it and immediately he commits a tactical mistake. Why did this happen? Possibly because he didn't check carefully the tactics in the position but he mainly deliberated about what to do (make a quick draw or play on).} Nxf3+ (16...
