Double Check Puzzle (Rated 1238): Win Material — Double Check

This chess puzzle is a classic forcing sequence built around king safety and a double-check style attack. In practical terms, the attacking side uses a pawn capture to open lines and drag the enemy king into a vulnerable square, then follows with a series of checks that leave almost no defensive choices. In chess endgame and middlegame positions like this, material can matter less than the ability to keep the king exposed and the pieces coordinated for a mating net.
