Ruy Lopez Bird Variation Puzzle (Rated 1412): Sacrifice on h2 — Kingside Attack

This Ruy Lopez middlegame shows a classic kingside attack based on a long opening sacrifice. White’s king looks safe, but the position is actually vulnerable because the dark-square bishop and queen can coordinate against the h-file and the king shelter. In practical classical chess, these attacks often begin with a forcing sacrifice that drags the king out, then uses queen and knight activity to keep the pressure alive. The key idea is not material count, but king safety and piece coordination.
