This looks better for black but there is no reason for white to go into this
line.
26 Nc3 fxe6 e5 opens things up and may simplify into a certainly non-lost
pawn-up ending for white as a better choice here. If white loses his
nerve, Bxf7 looks like it leads to a draw if white wants a perpetual. Nc3
looks like it leads to more.
