After a thematic pawn storm and a bishop sac, white manage to get a winning position because black queen will be force to take the white knight after Ne5 creating to much pressure on h5 now.

White is frightening to mate in 1 but it's black turn ... and that is enough to win

It looks like white is all good here with this near to promote pawn and material advandage ... but that's not the case at all, king is too exposed ...
