Albin Countergambit Puzzle (Rated 1161): Pin — Winning Tactic
A long middlegame pin can turn active-looking enemy pieces into tactical targets. In this Queen's Gambit Declined Albin Countergambit position, Black's advanced pieces create immediate pressure, but the exposed king and overloaded defenders make that activity fragile. White's key idea is to challenge the most dangerous attacker, remove it with precise timing, and exploit the resulting material imbalance. The pattern combines king safety, piece activity, and a tactical refutation rather than a mating attack.
