Indian Defense Colle System Puzzle (Rated 1321): Win Material — Fork Tactic

This puzzle shows a classic opening tactic where an advanced pawn creates a fork and forces a response. In the Indian Defense, active piece play often matters more than static structure, and a well-timed central push can hit two pieces at once while opening lines for the rest of the army. The key idea is not just the fork itself, but the follow-up that keeps the initiative and turns activity into a lasting material edge.
