[Event "Reykjavik"] [Site "?"] [Round "0"] [White "Sigurjonsson"] [Black "Smyslov"] [Result "0-1"] [ECO "A22"] [Opening "English: King's, 2.Nc3 Nf6 3.Nf3"] 1. c4 e5 2. Nc3 Nf6 3. Nf3 Nc6 4. g3 Bb4 {A developing move which prepares for rapid castling. It is more active than 4...Be7.} 5. Bg2 O-O 6. O-O {This positi on is still a popular way for both sides to play the English opening.} 6... e4 7. Ng5 Bxc3 8. bxc3 Re8 9. f3 { Smyslov has played this position for both White and Black.} 9... exf3 10. Nxf3 d5 11. cxd5 Qxd5 {An interesting position where White has the two center pawns(long term advantage) while Black has active piece play.} 12. Nd4 Qh5 13. Nxc6 bxc6 14. e3 {14.Bxc6 looks tempting but it actually leads to the loss of a piece after 14...Ng4} 14... Bg4 15. Qa4 Re6 {The right idea but wrong move order. Better was Be2 first. 15...Be2 16.Rxf6 Bb5 17.Qc2 gxf6} 16. Rb1 { A mistake which later exposes the rook to attack. 16.Ba3 Be2 17.Rf4 would be much better than the game continuation, as White's queen rook is actually safer on a1 than b1.} 16... Be2 17. Re1 Ng4 { Threatening a quick win after Qxh2+ and Rf6+.} 18. h3 Qf5 {This is a clas sic example of a double attack, with the queen hitting both the rook at b1 and the vulnerable f2-square.} 19. Rxe2 {19.hxg4 Qxb1 20.Rxe2 Qxc1+} 19... Qxb1 20. Qxg4 Qxc1+ 21. Kh2 { Black has won the exchange which gives him a winning material advantage.} 21... Rd8 22. Qb4 h6 23. c4 Qd1 24. Rf2 Qe1 { White resigned because he is the exchange down and losing his d-pawn.} 0-1
