Moscow Variation Puzzle (Rated 823): Crush with a Fork — Middlegame Tactics
This puzzle is a classic middlegame tactical shot where an active knight creates a forcing check that wins material by exploiting loose coordination. The key idea is not a long strategic plan, but a sharp tactical refutation: the king is driven into a vulnerable square, and the follow-up attack hits two important targets at once. In positions like this, piece activity matters more than static material, especially when the opponent’s queen and knight are overloaded or trapped.
