1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. a3 Bc5 5. Nxe5 O-O 6. Nxc6 dxc6 7. d3 {White is doing fine after 7. f3! Nh5 8. g3!. This position has occurred many times with colors reversed and the a-pawn back at home.} Ng4 8. Be3 Nxe3 9. fxe3 Bxe3 10. Qe2 Bd4 11. Qd2 f5 {The more straightforward 11... Qf6 leaves White in great difficulties. The king cannot escape: 12. O-O-O Bg4 13. Be2 (13. Re1 Bf2) 13... Bxc3 14. bxc3 Bxe2 15. Qxe2 Qxc3 and White will lose a second pawn.} 12. O-O-O f4 13. Kb1 Be3 14. Qe1 Qf6 {Preventing d3-d4.} 15. g3 Bg4 16. gxf4 {A good decision, boldly offering the Exchange. 16. Be2 f3 would be a disaster.} Bd4 {16... Bxd1? 17. Qxe3 Bh5 18. f5 looks a bit scary and I certainly don't believe Black could claim to be better.} 17. Rc1 {A blunder. White had to accept losing a pawn with 17. Be2 and he could expect some compensation. In the game Black gets a similar position up a pawn, but also with an extra Exchange.} Bf3 18. Be2 Bxh1 19. Qxh1 Bxc3 20. bxc3 Qxc3 21. Ka2 Rxf4 22. Bd1 Qd2 23. Kb2 b5 24. Rb1 Rd8 25. Kb3 a5 26. e5 {Extra material comes in handy when it's time to sacrifice.} Rxd3+ 27. Ka2 {27. cxd3 a4# is cute as the rook on f4 is not even necessary.} Rxa3+ 28. Kxa3 {If White declines the rook again, Black will insist: 28. Kb2 Rb4+.} Qc3+ {Black resigns, as 29. Ka2 Ra4 is mate, and after 29. Rb3 Black has his choice of ...Qa1# or ...Ra4#.} 0-1
