Van Geet Opening Berlin Gambit Puzzle (Rated 1062): Use an Intermezzo — Crushing Tactical Refutation
This puzzle shows a classic intermezzo idea in the opening: instead of recapturing or simplifying immediately, White inserts a forcing check that changes the whole tactical picture. The key is that Black’s queen is overextended and White’s pieces are active enough to exploit the exposed king and loose coordination. In classical chess, these short tactical refutations often decide the game by winning material and leaving the opponent with no comfortable defense.
