Today’s 5-second tactic

Cross,D
From the International Open tournament in Gasteiz last year (7-25-2013). Position after White’s 19th move (19.Nc6) White has what looks like a big advantage (extra pawn and threats) but appearances can sometimes be deceiving. A closer inspection of the position reveals that the White Queen is awkwardly posted. White had only calculated 19…Qd7(?) 20.Nfe5! with a clear edge. INSTEAD, a surprise awaits White…
BLACK TO PLAY AND WIN!

Gasteiz,Spain 2013.7.25 Doncea, Vladimir–Cross, Dominic: 19…Nxf2!! Brilliant and unespected! 20.Nxe7+ (If 20.Kxf2 Rxc6! 21.dxc6 Bc5+ crushes ) 20…Qxe7 21.Kxf2 Rc2+ 22.Kg1 And now the most precise way to win is 22…Qc5+! as 23.Kh1 goes off to 23…Ne4! And 23.Rd4 Qc3!; finally 23.Nd4 Ng4! ; in each case, Black has a winning attack.
