Van Geet Opening Novosibirsk Variation Puzzle (Rated 1185): Win Queenside Attack — Decisive Material Gain
This middlegame puzzle shows how a queenside attack can turn into a decisive material gain when the opponent’s king and pieces are slightly uncoordinated. White’s queen is active, but Black has a strong tactical resource based on opening the center and creating threats against the white queen and king. The key idea is to notice when a loose piece can be hit with tempo, especially if that move also opens lines for a discovered attack or a forcing check on the queenside.
