Learn How to Use an Intermezzo: Equality Tactic
This puzzle is a classic intermezzo idea in the middlegame: instead of recapturing immediately, the stronger side inserts a forcing move that changes the balance of the position. The key point is that the opponent’s active piece is vulnerable, and the tactical sequence relies on a check to gain tempo. In classical chess, these in-between moves often decide whether a position stays equal or swings toward a clear material edge.
