Rook Endgame Puzzle (Rated 1144): Win a Rook Endgame — Short Skewer

This chess endgame shows how active rook placement can decide a seemingly simple position. White’s rook is ideally placed to create a forcing check that also improves the king’s activity and exposes a loose piece. In classical chess, rook endgames often turn on tempo, king activity, and tactical motifs like skewer or discovered attack. Here, the key is to notice that the opponent’s king cannot safely ignore the threat because the rook behind it is vulnerable.
