16.Bxh6! gxh6 17.Qxh6 f5 18.Nf3 Nc6 19.Qg6+ Kh8 [19...Qg7?
would be a terrible mistake in view of 20.Rxe6!!]
[opening "e"-file for another major piece - the rook on e1.]
20…exd5 21.Qh6+ Kg8 22.Bc2! [transferring the light-colored bishop to the diagonal a2–g8, from where it can take an active role in the attack.]
22…Ne5 23.Nxe5 Bxe5 24.Bb3
24…Bb7 [Black has nothing better than giving back the piece.]
25.Qe6+ Kg7 26.Qxe5+ Qxe5 27.Rxe5
[Stockfish has a pawn more, better pawn structure and more active rooks. All these factors forced Critter to resign on move 69th.]
