Learn How to Win Material: Tactical Refutation
This Pirc Defense puzzle is a classic example of a tactical refutation in the opening. White has active piece play, but Black can answer with a forcing sequence that turns the tables by exploiting a pinned piece and a loose attacker. The key idea is that active-looking development can hide tactical weaknesses when one piece is overloaded or undefended. In positions like this, calculation matters more than general principles, because the best move changes the evaluation immediately.
