[Event "Federal Republic of Germany"] [Site "?"] [Round "0"] [White "Hunerkopf"] [Black "Spassky"] [Result "0-1"] [ECO "C44"] [Opening "Scotch Gambit"] 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Bc4 Nf6 5. e5 d5 6. Bb5 Ne4 7. Nxd4 Bc5 8. Be3 Bxd4 9. Qxd4 O-O 10. Bxc6 bxc6 {White lost time in order to weaken Black's queenside pawns. He should now play to consolidate by 11.O-O.} 11. f3 { This weakens White's kingside.} 11... c5 12. Qa4 {This is a big mistake. White's queen now gets cut off from the center and the kingside and Black's knight gives him a ready made attack on the weakened e1-h4 diagonal.} 12... Bd7 {It is important to drive White's queen off the fourth rank, so that after a subsequent ...Qh4+ Black's knight is not pinned onto his queen.} 13. Qa3 Qh4+ 14. g3 {Losing immediately. White has missed Black's 16th move. His best try would be 14.Kd1, though Black would keep an attack after 14...Qh5.} 14... Nxg3 15. Bf2 {White had counted on this counter pin, but by leaving the c1-h6 diagonal the bishop has exposed White's other weakness, the first rank.} 15... Qh6 {White resigned here, since he has only one way to avoid the check on c1 without losing his rook,} 16. Be3 {Which leaves him helpless after:} 16... Qh5 {Black will end up at least two pawns ahead with a continuing attack.} 0-1
