[Event "Riga"] [Site "?"] [Round "0"] [White "Sangla"] [Black "Karpov"] [Result "0-1"] [ECO "A46"] [Opening "Torre Attack: 3...c5 4.c3"] 1. d4 Nf6 2. Nf3 e6 3. Bg5 c5 4. c3 cxd4 5. cxd4 Qb6 6. Qb3 Ne4 7. Bf4 Nc6 8. e3 {This move cuts off the bishop at f4 from the defense of the d2- square.} 8... Bb4+ 9. Nbd2 {This knight is now pinned, fatally. 9.Nfd2 would have been wiser. The point is that in either case one of the knights will be at d2.} 9... g5 {This pawn cannot be ignored, because it will advance to g4, driving away the knight at f3, and when it leaves, the knight at d2 doesn't have enough protection.} 10. Bxg5 Bxd2+ 11. Nxd2 {Forced, because the king cannot capture because the bishop is protected by the knight at e4.} 11... Qa5 {Black renews the pin at d2, and also attacks the bishop at g5. White must lose at least one of his pieces, so resignation is justified.} 0-1
