Stated plan

Capture the f4 pawn to gain material advantage while keeping the king safe from the resulting e5+ check.

Reasoning

Black can win a pawn with e5xf4, since if White tries e4-e5+ the black king simply captures the advancing pawn (Kxe5), leaving Black up material with a strong passed f-pawn.
