A new pedagogical series in which we will look at a portion of a game from the previous weekend in which I miss some obvious tactic or other. Readers will be invited to practice their skill by seeing if they can spot what I missed.
We open the series with the game Moreno García - Horton, Huesca 2007, which after these opening moves:
1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Bc5 5.Nb3 Bb6 6.a4 a6 7.a5 Ba7 8.Nc3 Nf6 9.Bg5 h6 10.Bh4 O-O 11.Bd3 d6
reached the following position:
and then proceeded 12.O-O Ne5 13.Qd2 Ng6 14.Bxf6 Qxf6 15.Nd5 Qd8 16.Kh1 Be6 17.Ra3?! Ne5 18.Qb4? Ng4 and Black won swiftly.
However, somewhere in the sequence between the diagram and move 16 Black missed a simple and thematic tactic. Can you see what I did not?
(Answers in the comments box - so don't read it until you've had a go at solving it. The game can be played through below.)
