Old Indian Defense Beginner Puzzle (Rated 1105): Win Material — Crushing Fork

This puzzle comes from the Old Indian Defense and shows a classic opening tactic where activity beats structure. Black can use a forcing central thrust to create a fork on key white pieces, turning a balanced opening into a decisive material win. The idea is not a mating attack, but a sharp tactical refutation based on piece coordination, tempo, and the fact that White’s pieces are slightly overextended in the middlegame transition.
