White probably should seek an improvement before if she wants to engage in future theoretical duels, as it seems that Black has no problems in this position anymore. 14. f1g3  14... e7f8 Now the pin with 15.Bg5 is no longer unpleasant, since Black can just play h6, and the bishop cannot go to h4. 15. h2h3  15... a8b8 The first new move. 16. c3b4  16... c5b4  17. d3d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] Paehtz correctly uses her chance to get active play. 17... e5d4  18. f3d4  18... g7g6  19. c1f4  19... f6d7  20. b2b3 [%c_effect b3;square;b3;type;GreatFind;persistent;true] Another good move, restricting the knight on a5. 20... b8c8  21. a1c1  21... a5c6  22. d4c6  22... c8c6
