[Our pedagogical series in which we look at a portion of a game I played the previous weekend in which some obvious tactic is overlooked. Readers are invited to practice their skill by seeing if they can spot what was missed.]
Luis Vitalla (2199) v Horton, Aragón Team Championship 2008. Position after 31.Bd2-g5.
Black now finished off a well-played Slav (no, really) with 31...Nd7 32.Be7 Qd5 33.Bc5 Nxc5 34.Rxc4 Ra8! and White resigned.
What glaring error (or errors) can you find in this sequence?
