Van Geet Opening Billockus Johansen Gambit Puzzle (Rated 1063): Fork — Decisive Material Gain
This puzzle shows a classic tactical sequence in the Van Geet Opening where Black converts activity into a decisive material gain. The key idea is a fork-based tactic: one move creates multiple threats at once, forcing White’s pieces into awkward coordination. Because White’s king is still in the center and several pieces are active but loose, Black can exploit tactical pressure rather than rely on long-term strategy. The position is a good example of how opening development can turn into a middlegame tactic.
