This is the situation at the start of the ending. It represents best play
from the root. Kasparov found 61. Nd4!, which was the only winning move.

This is the position after Adams' mistake, 61. ... Na6. It shaved many moves
off of the mate distance, so it should be regarded as an error, and was by far
the worst mistake in the ending.

Adams' 62. ... Kg6 was also slightly sub-optimal. Kasparov found the best
move, 63. Nd4. Adams spent the rest of the game trying to get his king in
front of the pawn, rather than admit the game is completely lost and try to
stave off mate for the longest time. This decision can't be faulted, of
course.

found 65. Ne6, also one of four best moves.
