Petrovs Defense Three Knights Game Puzzle (Rated 1245): Win Material — Kingside Attack

This puzzle comes from the Petrov's Defense, Three Knights Game, where White uses active piece placement to create a decisive kingside attack. The key idea is that a pinned defender can be overloaded, allowing a forcing sequence that wins material and leaves Black’s king under lasting pressure. In classical chess, these tactical shots often appear when development is lagging and one piece is doing too many defensive jobs at once.
