Learn How to Use an Intermezzo: Winning Material
This middlegame puzzle shows a classic intermezzo idea: instead of recapturing immediately, White inserts a forcing check that changes the position first. The key is that the enemy king is exposed and the rook on the sixth rank creates direct pressure on the kingside. By using a forcing move, White turns a tactical skewer into a winning material sequence and keeps the initiative. The position rewards active piece placement over passive defense.
