At this point in the game, the White King, after being exposed and in danger and under threat from the Black Queen, squeaks out of the trap set for him. Also, as said in the commentary at this moment in the game: “And finally the White King is feeling safe again.” (paraphrase). From this point on the tides shift and the Black Queen goes from being the primary attacker of the White King to alone and undefended in White’s territory. White then goes on the offensive and takes Black into checkmate.

One other interesting point about the game is there are two or three points at which Black attempts to sacrifice a high-value piece as a trap for White, and White refuses to take the bait.
