If 19. ... Kg8 then follows 20. Qe7 (threatening 21. Rf8 mate) and how can black stop the mate short of giving away pieces a la Fritz (e.g. 20. .. Qe8, 21. QXQ+ .. Kg7, 22. Qf7+ .. Kh6, 23. Rf5 and mate next move or 20. .. QXg2+, 21. KXg2 and mate next move).
So 19. ... Kg7 is better when if 20. Qe7+ (20. Qe5+ is of course also playable) .. Kh6, 21. Q ...[text shortened]... the Q and must have excellent winning chances.
So black must play on hoping for 21. Rf6??[/b]
Originally posted by FlyingDutchmanTrue, but after 22. hXR black has 2R and B for his Q and white has nothing further to throw into the attack.
Rxg6 is check, so Nxe7 is not possible?
White needs to mate or make decisive material gains or else will end up having to resort to taking a draw by perpetual in all these lines.

And as far as I can see, any other legal moves either flat out give the queen away (and thus simply postpone the checkmate), or completely ignore the threat of checkmate altogether.
Originally posted by FabianFnasMoving the queen to e8 or the f-file seems to be the only thing to postpone mate...but then the queen is lost and mate will soon follow anyway..I say the correct move is to resign.
