This line is facinating, there are some hidden tactics that are not in the PV
that are beautiful, for instance at the end, instead of Qa8, Qb7 looks better
but Ng6!! is excellent (Qxe7/ Nxe7+ Kh7/ Rh5#) and if Rb8 / Rh5! fxg6/ Qe6+ Qf7
/Rh8+ +- (Carbon analysis).
White is threatening at all times Qh4 and it is nice how the white pieces
coordinate to threat Rh8# and have everythind defended. That is why Black
manouver to force the white king to be in h4.

BUT, Bxg7 is a winning move, no doubt about it, and easier for a human to
evaluate.

Miguel
