Reti Opening Beginner Puzzle (Rated 1447): Use Discovered Attack — Tactical Refutation
This middlegame puzzle from the Reti Opening shows how a discovered attack can turn a strong-looking position into a tactical collapse. White’s pieces are already active, and the black king is exposed enough that a forcing move can create immediate threats while also winning material. The key idea is to use a check as a trigger, forcing the king to respond and opening lines for another piece to attack a valuable target. In classical chess, these tactical motifs often decide games faster than slow strategic plans.
