Learn How to Spot a Mate in 2: Intermezzo Tactic
This puzzle comes from the Sicilian Defense, Smith-Morra Gambit Accepted, where White uses a forcing intermezzo to exploit the exposed black king and loose back-rank coordination. The key idea is that a checking move can be used as a tempo-gaining interruption, creating a mating net before Black can organize defense. In classical chess, these short tactical shots often appear when development and king safety are badly mismatched, especially in the middlegame.
