BARDEN CHESS

Stuart Conquest (England) v Yuri Yakovich (Russia), European championship, Saint-Vincent 2000. The British grandmaster had a difficult start to the tournament. He booked in at a cheaper room to save the cost of the official hotel, only to find that the organisers excluded him from the first round and threatened to default him from the tournament. Here as White (to move) he has sacrificed two pawns for what looks a nebulous attack. How did he justify his gambit and force victory?
