◇ Just read — no move neededThe hole becomes a door
The technique position of 12.3, now played to the end. The missing a-side elephant is the hole; the horse is the drill; the pawn is the wedge that stops the defenders from sealing it back up. Route the horse through g4, e5 and f6, and the moment the palace pieces are pinned to their posts, the pawn walks in behind them. The engine scores this about +3 — comfortable, as long as you never let the horse be traded for the last defender.
