41... Rb2.

it is not clear which moves were played and which were analysis from here on (see Note).

42. Kf3 Qf1+ 43. Kg4 f5+??

43... Rb2 still leaves Black with an overwhelmingly won position.

44. exf5= gxf5+?

44... Qxf5+=.

45. Kg5?

45. Kh5!!, e.g. 45... Qh3 46. Qf3!.

45... Bf6+?

45... Qh3! , with the point that 46. Qf3? (46. Qxf5=) now loses after 46... Rxd2 47. Rxd2 Be3+! 48. Qxe3 Qg4+ 49. Kh6 Qg7+ 50. Kh5 Kh7.

Event information: Tournament report.

Note: The live boards file gave the conclusion of the game as '42. Kf3 Qf1+ 43. Kg4 f5+ 44. exf5 gxf5+ 45. Kg5 Bf6+ 46. Kg6 Qh3 47. Bg5 Rxe2 48. Qxe2 Bxg5 49. Qe6+ Bf6 50. Qe2 0-1'. The last two moves are illegal and must be spurious analysis moves. All the others are plausible, but lead to a winning position for White. How was it that Black won?
