Who stands better here? There is a certain amount of symmetry in play, in particular the two side's Knights are exact equals. Both Queens hover threateningly around the opponent's King. It's the sort of position where a tempo can mean a lot, but as it happens the fact that it's Black's move turns out to be outweighed by White's safer King. The absence of a Black counterpart on f7 to White's f2 pawn is strongly felt.   39...Qe8? ( The computer holds with 39...Qe4+ 40.Kh2 Nh6! combining attack (Ng5+) and defence  ) 40.Ne6!

Suddenly it's over. White threatens g4 then h5 and Black is paralysed by the need to keep g7 and f6 covered   40...Kh6 41.Nf8 An elegant move, cutting off defence of h8 (41.Nf8 Trying to continue costs more than just a Knight  41...Qe4+ 42.Kh2 Nxh4 43.Qh8+!
