1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. e2e3 Robson has been faithful to the most classical of the Nimzo-Indian variations throughout the tournament, showing that it's possible to gain attacking positions with the queen's pawn as well. 4... e8g8  5. f1d3  5... d7d5  6. a2a3  6... d5c4 So decides to keep his bishop. 7. d3c4  7... b4e7  8. g1f3  8... c7c5  9. e1g1  9... a7a6  10. d4c5  10... e7c5  11. d1e2  11... b7b5  12. c4a2  12... c8b7  13. e3e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] White's typical plan in this pawn structure. The diagonal opens for the bishop and there's the possibility of playing e4-e5 and trying to attack on the kingside. 13... d8c7 [%c_effect c7;square;c7;type;GreatFind;persistent;true] An accurate defensive move. 14. e4e5  14... f6d7  15. c1f4  15... b7f3 [%c_effect f3;square;f3;type;GreatFind;persistent;true] The knight needs to be captured so that Black can attack the e5-pawn. So was played all this very quickly, he was probably still on preparation. 16. e2f3  16... b8c6  17. c3e4  17... d7e5  18. f3h5 The first new move of the game. 18... c5d4  19. a1d1  19... f8d8 [%c_effect d8;square;d8;type;Mistake;persistent;true] The price of a mistake is very high in this position and now Black is hopelessly lost. 20. d1d3 [%c_effect d3;square;d3;type;GreatFind;persistent;true] The rook lift through the third rank is fatal. 20... c7e7  21. d3h3  21... h7h6  22. f4g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] Robson will play all the best moves until the end of the game. He is an excellent attacking player. 22... e7e8  23. g5h6 [%c_effect h6;square;h6;type;GreatFind;persistent;true] White should play for mate. 23... e5g6  24. h6g5  24... f7f6  25. f1e1 [%c_effect e1;square;e1;type;GreatFind;persistent;true] There are other winning moves, but I like this one. White can also sacrifice immediately: 25... a8a7 This move doesn't help much, but there's nothing that can be recommended. 26. e4f6  26... d4f6  27. e1e6 Black's position collapses completely. 27... e8f7  28. e6f6  28... g7f6  29. h5g6
