Queen's Gambit Declined Austrian Defense Puzzle (Rated 1356): Win Material with a Fork — Queen's Gambit Declined
This puzzle shows a classic opening tactic in the Queen's Gambit Declined: a knight fork that creates a decisive material gain. The key idea is that an active knight can jump into a square where it attacks multiple important targets at once, often with check. Here, the fork also exploits the exposed king and the loose coordination of the white pieces, turning a normal-looking opening position into a forcing tactical sequence. In classical chess, these short combinations are often decided by piece activity and king safety.
