16. Rac1 Nd7 17. Rfd1 Nc5 18. b4 Na4?! 18... Ne4 19. Rc6 e5 20. Rdc1 Rxc6 21. Nxc6 Kf6 is almost equal. 19. Nb5 If 19. Nc6?! then 19... Rc7 stops the white initiative in its tracks. 19... Rxc1 20. Rxc1 a5 21. a3 Rd8 22. Rc7 Rd5 23. Na7 axb4 24. axb4 e6 24... Kf6!? 25. Nc6 Rd2? Now the side-lining of his knight finally proves fatal for Black. With 25... Nb2! he would have good chances of saving the game; for example 26. e4 Rd2 27. Ne5 Nd3 28. Rxf7+ Kg8 29. Nc4 (29. Rd7?? backfires: 29... Rxf2+ 30. Kg1 Nxe5) 29... Rc2 30. Nd6 Nxb4 31. Rb7 Nd3 and White still has the initiative but objectivelty Black's counterplay should be sufficient for a draw. 26. Ne5 Rxe2 27. Nxf7 h5 27... Kf6 28. h4 Rb2 29. Nh8! g5 (29... Rxb4 30. Rf7+ Ke5 31. Rxh7 and the g-pawn also drops) 30. Rf7+ Ke5 31. hxg5 Nc3 32. Kh3 28. Ng5+ Kf6 28... Kg8 29. Kf1 Re5 30. f4 Re3 31. Kf2 Rb3 32. Nxe6 29. Kf1 Rxf2+ After 29... Rb2 30. f4 Kf5 31. h3 the black king is caught in a mating net. 30. Kxf2 Kxg5 31. Ke3 Kg4 32. b5 Kh3 33. Rc4 Nb2 34. Rc2 1-0 [Mueller,K & Pajeken, W]
