[Event "Groningen"] [Site "?"] [Round "0"] [White "Smyslov"] [Black "Kottnauer"] [Result "1-0"] [ECO "B90"] [Opening "Sicilian: Najdorf"] 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be2 e6 {With this m ove Black transposes to the Scheveningen Sicilian, which is a favorite defense of mine.} 7. O-O b5 {This move is a mistake since Black is undeveloped and therefore isn't ready to meet White's play on the h1-a8 diagonal. 7...Be7 8. Be3 O-O 9.a4 when Black's little center and semi-open c-file give him good chances, as I have demonstrated on a number of occasions.} 8. Bf3 Ra7 { 8...Bb7 9.e5 dxe5 10.Bxb7 Ra7} 9. Qe2 Rc7 { 9...Rd7 10.e5 dxe5 11.Nc6 Qc7 12.Nxb8 Qxb8 13.Bc6 when White wins the exchange. } 10. Rd1 {White's lead in development gives him a winning initiative.} 10... Nbd7 11. a4 {White uses his lead in development to start a queenside attack.} 11... bxa4 {11...b4 Trying to keep the position closed wouldn't help after 12. Na2 a5 13.Nb5 when Black has problems defending his d-pawn.} 12. Nxa4 Bb7 { 12...Be7 Preparing to castle was better but 13.Bd2 would still give White a big development advantage with 14.Ba5 being threatened.} 13. e5 {White uses d in development to start play in the center which is where Black's king has remained.} 13... Nxe5 {13...dxe5 14.Bxb7 exd4 15.Bxa6 Bc5 16.Nxc5 Nxc5 17. Bb5+ Ke7 18.Bf4 would be good for White because of Black's exposed King.} 14. Bxb7 Rxb7 15. Qxa6 Qb8 16. Nc6 { White removes Black's best placed piece: the knight on e5.} 16... Nxc6 17. Qxc6+ Nd7 18. Nc5 {The culmination of White's lead in development. The idea is to take advantage of the pinned Black knight on d7.} 18... dxc5 { 18...Rc7 19.Nxd7 Rxd7 20.Ra8 wins the Black queen.} 19. Bf4 {White plays a deflection sacrifice which Black can't except due to his weak back rank.} 19... Bd6 {19...Qxf4 20.Qc8+ Ke7 21.Qxb7 when Black would also lose his knight because of the pin on the seventh rank.} 20. Bxd6 Rb6 21. Qxd7+ { Black resigned because he would be a piece down after 21...Kxd7 22.Bxb8+.} 1-0
