1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... a7a6  6. c1g5  6... b8d7 Nowadays, this move is at least as popular as the old main line with 6...e6. 7. d1e2 The development of the queen on e2 is the modern approach, either now or after 7.f4. This plan was analyzed extensively in Negi's 1.e4 repertoire book, in my opinion, one of the best opening books ever written. 7... e7e6  8. e1c1  8... d8c7  9. g2g4 [%c_effect g4;square;g4;type;Interesting;persistent;true] 9... h7h6 [%c_effect h6;square;h6;type;GreatFind;persistent;true] The safest move, taking the bishop out of its menacing post. 10. g5d2 [%c_effect d2;square;d2;type;Interesting;persistent;true] Not the most imposing square, but in chess, as in life, you can't always get what you want. 10... b7b5  11. a2a3 [%c_effect a3;square;a3;type;GreatFind;persistent;true] It's necessary to stop the b-pawn. 11... a8b8 [%c_effect b8;square;b8;type;GreatFind;persistent;true] Both players show excellent preparation. 12. f2f4 The position is fresh, and White can look for interesting alternatives. 12... b5b4  13. a3b4  13... b8b4  14. d2e1 A new move. 14... c7b6 [%c_effect b6;square;b6;type;GreatFind;persistent;true] Forcing the knight back. 15. d4b3  15... f8e7  16. e1f2 [%c_effect f2;square;f2;type;Inaccuracy;persistent;true] 16... b6c7 [%c_effect c7;square;c7;type;Inaccuracy;persistent;true] 17. g4g5 [%c_effect g5;square;g5;type;Inaccuracy;persistent;true] 17... h6g5  18. f4g5  18... f6h5 [%c_effect h5;square;h5;type;Inaccuracy;persistent;true] 19. e2d2  19... d7c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] The right way to attack, as we've seen in the variations before. This move is strong because it removes one of the key defenders of the king. 20. b3c5  20... d6c5  21. g5g6 [%c_effect g6;square;g6;type;Inaccuracy;persistent;true] Black will be the one benefiting from open f-file. 21... f7g6  22. h1g1  22... e8g8  23. g1g6  23... c7a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] 24. c1b1 Bjerre will miss many winning chances on the next moves. 24... e7f6  25. g6f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true] The only way to keep fighting. The bishop is too strong. 25... h5f6  26. e4e5 [%c_effect e5;square;e5;type;Inaccuracy;persistent;true] 26... f6g4  27. f2g3  27... a5b6  28. b2b3  28... b4d4  29. f1d3  29... f8d8 [%c_effect d8;square;d8;type;Mistake;persistent;true] This is a clear mistake and now White gets back into the game. 30. d2e2 Now the position is totally unclear and chaotic. 30... b6a5  31. b1b2  31... a5c7  32. d1f1  32... g4h6  33. d3c4 Though the machine indicates equality, the position is more difficult to play with Black because his king not safe. 33... c7e7 [%c_effect e7;square;e7;type;Inaccuracy;persistent;true] A natural defensive move that is a mistake. 34. c3e4  34... d8f8  35. f1g1 [%c_effect g1;square;g1;type;Inaccuracy;persistent;true] 35... c8b7  36. e4f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true] 36... g8h8  37. g3f2  37... d4f4 [%c_effect f4;square;f4;type;Mistake;persistent;true] 38. f2e3  38... f4f6  39. e5f6  39... e7f6  40. b2b1  40... h6f5  41. e3c5  41... f8c8  42. c5a3  42... b7d5  43. a3b2 White's bishops are too strong.
