... but enough of the self-loathing, let's cut to the chase. The following has a certain flavour of sadism. It comes from the live chess24.com broadcast of the Carlsen-Caruana tie-breaks after Fabi had resigned the first game. Peter Svidler and Anish Giri were providing viewers with a thumbnail of how to win in the following sort of position which incidentally didn't happen in the game but might have done had Black carried on playing rather longer than was sensible. Of course, Fabi knew better than to do that.
The position shown above is a reasonably easy win for White though there are a few pitfalls for the unwary along the way if you are careless. The quickest way starts 1.h7+ and is actually forced mate in five but Alexander Grischuk mentioned another way which, though considerably slower, is much wittier and arguably more sadistic, offering Black the briefest glimpse of salvation before having it cruelly snatched away.
Grischuk's way begins 1.g7 and Black has nothing better than to move his rook along the back rank, say, 1...Ra8 (after 1...Kh7 White simply plays 2.Rf8 and Black can't stop the g-pawn promoting or Rh8+ followed by same; the black rook can give a few checks but the white king strolls over to the queenside to close the game out).
Now comes the fun part: 2.Rf8+: it's easy to imagine a Black player suddenly getting his hopes up. He sees 2...Rxf8 3.gxf8+ Kxf8 and for one ecstatic moment envisages a draw. But it's a mirage. 2...Rxf8 ("Just when I think I'm out...") 3.Kg6! ("... they pull me back in!")
