1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. d3 b5 6. Bb3 Be7 7. Ng5 Here white could gain a comfortable position with 7. O-O and an attempt to slowly build up to the main idea of playing d4 with such moves as c3, Re1, Nbd2, Nf1, Ng3 and then d4. 7... O-O 8. Nc3? White clearly is not playing the Ruy Lopez as an attempt to build up a powerful centre, and this move reduces his future options severely enough for it to be said that black is slightly better here. 8... h6 9. Nf3 d6 10. Be3 Bb7 11. Qd2 Ng4 12. O-O-O Na5 With both white bishops now threatened with unavoidable capture, white must accept that he is in some danger since without the bishops, the defensive task may be hard. 13. Nd5 Nxb3+ 14. axb3 Black is now in the happy situation where he has some choice what to do next. 14. ...c5 gains queenside space in preparation for an attack; 14. ...Bxe5 cripples white's centre and gives black chances of building there himself; 14. ...Nxe3 postpones this decision for another move; 14. ...a5 is also an inevitable move that could be played now. 14... f5 Instead I chose to undermine the white centre this way. The threat of f4 winning the piece forces white to take what I thought was action that he did not want to. Initially I had considered that only 15.Nxe7+ Qxe7 16.exf5 saved white, but 15.h3 forces black's hand and limits the damage. 15. Nxe7+ Qxe7 16. h3 Black now has another choice, but this time a more serious one, since the resulting position is very different. 16. ...fxe4 17.hxg4 exf3 18.g3 was a line I examined very carefully, but ultimately I rejected it for the practical consideration that white has something to do, whereas my choice reduced his play to almost zero. In fact, Fritz reckons that this line is slightly better, since black has plenty of time to defend while launching his own onslaught, while the open game allows black to expand in the centre. 16... Nxe3 17. Qxe3 f4 Not necessarily best, but white has now got to find something to do while black can quietly build up on the queenside. 18. Qe2 c5 The "master plan" was to give white very little chance of any activity while creating my own, so this move serves this by controlling the d4- square. 19. Rhe1? The task of looking for activity is clearly too much for white, who spends the rest of the game wandering aimlessly while black closes in for the kill. 19... a5 20. Qd2 b4 21. c3 Rfc8 22. g3 a4 black has plenty of threats here, and now he begins to carry them out. 23. bxa4 fxg3 24. b3?? White hastily seals the a-file, only to fall victim to a worse threat. Black's next seals the win since white has too much to do to avert disaster. 24... Qf7 25. Re3 Qxb3 26. Qc2 Qa3+ 27. Kd2 gxf2 28. Rf1 Rxa4 29. d4?? the final blunder. Black's Rfc8 earlier suddenly shows its value, since it is easy to open that file up. 29... cxd4 30. cxd4 Rxc2+ RESIGNS. Mate follows shortly, eg 31. Kxc2 Bxe4+ 32. Rxe4 Qc3+ 33. Kd1 Ra2 34. dxe5 Qa1# 0-1 [James]
