Learn How to Spot Mate in 2: Back Rank Mate
This middlegame puzzle is a classic mating net: the attacking side uses a forcing check to drag the enemy king and queen into a cramped defensive setup.

In classical chess, these patterns often appear when heavy pieces coordinate against an exposed king and the back rank becomes vulnerable.
