The diagram shows the position after White's 70th move when the 7-man endgame with Knight an two pawns against Bishop and pawn commences. The correct result should be a draw.
Black could handle the position in various ways; for example, 70...h4 is playable but Black chose to leave the pawn on h5 and manoeuvre with his Bishop. Eventually he did play the pawn to h4.
After playing correctly for some time, Black began to go wrong, making his choices harder.
Then, as so often happens in such pressure situations, he made a fatal mistake. Th second diagram position arose after White's 83rd move. Here there is only one satisfactory move, which Black failed to find. Instead he allowed White to improve the relative king positions which won the game.
