For a moment I thought Mamedyarov had resigned in a winning position!
50...Ng7+ 51. Kg5?? h6+!

But 51. Qxg7+ followed by 52. Bh6+ mates. Amazing that the king needed
to be at h5 to make this critical variation work.

I was sorry to see that Mamedyarov's creativity was not rewarded in the
end. A fascinating position after Black's pawn sacrifice at move 28.

Meanwhile, Polgar beat Sokolov with a nice kingside attack, moving into
clear first.
