I think I would score 100% in correspondence chess from this position against
any strong opponent with white.
OTB almost everything can happen if you have a bad day.

A firmly blockaded passed pawn is potentially a weakness.
The pawn on e4 blocks the e-file and the square e4 for the knight. Therefore
black is deprived of all counterplay.
