Chess Academy: A subtle blunder
[Title "White to move"]

White can play Nb5 followed by Nc7 but wouldn't Black play Rf8 beforehand?

1what was the last move before this position (by black)? – user8213 Sep 26 '15 at 2:08
This is a familiar tactic I often get to use myself in another opening line. If black plays 1... Rf8, then comes 2. Bc7! Qe8 3. Nd6 Bxd6 4. Bxd6 and black loses the exchange anyway.

Chess is about patterns. Since I was familiar with the pattern, I spotted this tactic immediately.

1Thanks, this is a wonderful answer. It is interesting how threatening to fork the Rooks allows you to guarantee a Rook capture even when the fork is supposedly evaded. This is something I've seen in Chess often, where there is some sort of balance of power that maintains unless one blunders. – AturSams Sep 23 '15 at 15:36
