Learn How to Spot Swallowtail Mate: Mate in 2
This puzzle is a classic middlegame mating pattern built around king safety and forcing checks. The attacking side uses a queen-led combination to drive the enemy king into a vulnerable square, where the final net is delivered by coordinated major pieces. The key idea is that the defending king has too few safe squares, so each check narrows the escape route until checkmate becomes unavoidable. In classical chess, these patterns often appear when the king is exposed and the pieces are active.
