Van Geet Opening Novosibirsk Variation Puzzle (Rated 1405): Win with a Defensive Move — Classical Chess
This middlegame puzzle shows how a defensive move can be the most powerful practical choice. White is under pressure from an advanced black knight and active black pieces, but the position also contains tactical resources based on king safety, pinned pawns, and loose pieces. The key idea is to use a forcing move that changes the nature of the position, turning defense into initiative and creating a clear advantage through tactical refutation rather than passive consolidation.
