Black offered a draw.

27. Rxf8

" 27. Re1 Kf6=" (Ludgate). "Now Black has a winning ending" (unknown annotator, ICU games archive), but the move played is fine and the game should still be easily drawn.

The losing move. 34. Bc6 Bb1 35. a3 Bc2 36. Ba4 g5 37. Ke3 gxh4 (37... g4 38. Kd2 and White is no worse) 38. gxh4 and the black king has no way to infiltrate.
