However, her reaction 12. c1e3 albeit obvious, turned out to be almost a decisive mistake $1 12... c8d7 [%c_effect d7;square;d7;type;GreatFind;persistent;true] Not just development, this is also a prophylaxis against the opponent's tactics $1 13. a4d1  13... f6g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] Now Black's attack is running like a snowball on a steep slope. 14. e3f4  14... e5g6  15. e2e3  15... g6f4  16. g3f4  16... d8h4 The black pieces are entering the play with ease, while the white king remains in the center. Both the f2- and e3-pawns are now under fire. 17. d1d2  17... c5d4  18. e3d4  18... f8e8  19. e1f1  19... d7f5 Same ease. Lagno has created the deadly threat Bf5-d3+ followed by Re8-e2 $1 20. a1e1 The e2-square is covered... 20... f5d3  21. f1g1  21... g4f2 [%c_effect f2;square;f2;type;Brilliant;persistent;true] But here is another problem $1 The e1-square is opened for the black pieces to infiltrate. 22. e1e3  22... e8e3  23. d2e3  23... f2g4 Incredible $1 After conducting the attack with such ease and elegance, Lagno stumbles at the very final step $1 24. e3g3  24... h4f6 An instinctive reaction: keep the queens alive, mate the king. 25. g3d3  25... f6f4  26. g2f3 Now Tan has managed to stabilize her situation and escaped the worst. Black still has plenty of compensation but is not winning anymore. 26... a8e8  27. c3e2  27... f4g5  28. f3g4  28... g5g4  29. g1f2  29... g4h4  30. f2g2 Missing another chance to play for the win. 30... h4g5  31. e2g3 From here on, both players play extremely accurately. 31... e8e3  32. d3c4  32... b7b5 [%c_effect b5;square;b5;type;GreatFind;persistent;true] An important in-between move. 33. c4c6  33... h7h5  34. h1f1 [%c_effect f1;square;f1;type;GreatFind;persistent;true] Having the rook out is far more important than the knight. 34... h5h4  35. c6c7  35... h4g3  36. c7f7  36... g8h7  37. f7f5 Forcing a more or less drawish rook endgame. 37... g5f5  38. f1f5  38... g3h2  39. f5b5  39... e3e2  40. g2h1  40... h7h6  41. d4d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] But White still had to be careful $1 41... g7g5  42. d5d6  42... g5g4  43. b5d5  43... g4g3  44. d5d1 Just in time $1 44... e2e8  45. h1g2  45... e8g8  46. d6d7  46... g8d8  47. g2g3  47... d8d7  48. d1h1
