Old Indian Defense Fork Intermediate Puzzle (Rated 1046): Win a Fork — Decisive Material Gain

This puzzle is a classic example of a long middlegame tactical refutation where activity beats raw material. White is down material, but the pieces are coordinated around the center and the black king is still vulnerable to tactical pressure. The key idea is a fork motif: a single active knight jump creates multiple threats at once, forcing the defender into awkward replies and allowing White to win major material. In practical classical chess, these positions reward initiative over static count.
