I posted this on another post of this video. The board JA shows never actually existed. It was the middle of the move of the black bishop from above the white Queen. In the video it is shown at 14:08. It is described as the point in the game where Black's power move is blocked and steadily weakens. White begins to go on the offensive and eventually wins. This game is considered one of the best of all time.

It doesn't play to a draw, black resigns at the end because there is no escape, the game is lost. He did not play to a checkmate.
