Old Indian Defense Czech Variation Puzzle (Rated 1191): Remove the Defender — Crushing Opening Tactic

This puzzle shows a classic removal-of-the-defender idea in the opening. Black’s active bishop and queen coordinate against White’s kingside and central pieces, creating a tactical sequence that wins material and leaves White’s position under heavy pressure. The key motif is that one defended piece can be eliminated, opening lines for a follow-up capture on a more valuable target. In classical chess, these short forcing combinations often decide the game before development is complete.
