27. Rc6+!! bxc6 (27... Ke7 28. Nf5+ Kf8 29. Bxe5 ± +– ) 28. a8=Q, as 28... Rxa8? loses immediately to 29. Qxc6+ Ke7 30. Nf5+.

27... Ke7 28. Bxe5?

28. Rc7+ Nxc7 29. Qxb4+.

28... fxe5 29. Nc7 Rxh2+??

29... Qxf2 and to stave off mate White has to go for 30. a8=Q Rxa8 31. Nxd5+ Ke6 32. Nc7+ Kf6 33. Qxa8 Rxa8 34. Rxa8 but the advanced e-pawns are then fatal.

30. Kg1?

30. Kxh2! wins, as now 30... Qxf2 31. Nxd5+ Ke6 32. a8=Q leaves White with an overwhelming material advantage.

30... Rxg2+ 31. Kxg2 Qf3+?

Too hasty. The less-than-obvious 31... e3!! wins.

32. Kg1 Nf4 33. Qxb4+?

33. Nd5+! Rxd5 (33... Kf7? 34. Nxf4) 34. Qxb4+ Kf6 35. Ra6+ Kg5 36. Qe7+ Kh5 37. Qf7+ Kh4 38. Rh6+ gxh6 39. Qf6+ Kh5 40. Qf5+ Kh4 41. Qf6+ with perpetual check.
