1. d4Nf6 2. c4e6 3. g3d5 4. Bg2Nbd74... dxc4 Leads to more lively play
5. Nf3Be7 6. O-OO-O 7. Nc3c6Not of course 7... dxc4 8. e4Nb6 9. Qe2c5 10. Rd1 with strong pressure for the pawn sacrifice
8. b3b6 9. Bb2Ba6More active than the usual Bb7 which would allow White to prepare e4 and get a somewhat freer game.
10. Ne5Nxe5 11. dxe5Nd7 12. cxd5cxd5 13. Re1Rc813... Nxe5 14. Nxd5! is better for white
14. Rc1 More accurate was a3 so that if Bc5 then b4 driving the bishop back
14... Bc5 15. a3Now had to be played against the threat of Qg5
15... Nxe5?15... Qg5 was not good, owing to 16. b4Be7 17. f4Qg6 18. e4 etc but it was possible to play simply 15... Re8 and after 16. b4Bf8 take control of the c4 square
16. Nxd5exd5 Overlooking white;s 19th move.Better was 16... Ng4 17. e3Nxf2 18. Kxf2exd5 19. b4Be7 20. Qxd5Qxd5 etc with an equal position
17. Bxe5Bxa3?!Creating tactical chances whilst Bb7 would be too passive
18. Rxc8Bxc8 19. Bxg7!Kxg7 20. Qa1+d4 21. Qxa3a5 22. Qb2Qf6 23. Rc1 A direct attack on the d4 pawn, which is pressing down on e2 unpleasantly would not be effective23. Rd1Rd8 24. Rd3(24. b4axb4 25. Qxb4Rd6)
24... Bf5 25. Rf3Qe5 followed by f6, would both be adequate in defence and in the b4 line Black's b pawn may even become dangerous. White therefore decides to target the weak c6 square
23... Be6 24. Rc6Rb8?This passive move allows the exchange of the dangerous black bishop. As Szabo pointed out right after the game, a double pawn sacrifice would have created good chances24... d3! 25. Qxf6+Kxf6 26. exd3Rc8 27. Rxb6(27. Rxc8 loses after 27... Bxc8 28. Bd5Be6 etc)
27... Rc1+ 28. Bf1Ke5 29. Kg2!(29. f4+?Kd4 30. Kf2Ra1 followed by Ra3 is in black's favour)
29... Bd5+ 30. f3Rc2+ 31. Kh3Rf2 and despite being 2 pawns down black has serious chances
25. Bd5d3 26. Qxf6+Kxf6 27. exd3b527... Ke5 28. Bxe6fxe6 29. Kf1Kd4 was somewhat better
28. d4threatening Bxe6, fe, d5
28... Rd8 29. Bxe6fxe6 30. Rb6b4 31. Ra6Rxd4 32. Rxa5Rd3 33. Rh5Rxb333... Kg6 34. Re5Kf6 35. Re3
