Stated plan

Attack the loose knight on e4 with f2-f3 to gain tempo and space.

Resolves to f2f3 · −562cp

Reasoning

The black knight on e4 is unsupported apart from tactical tricks; simply attacking it with f2-f3 forces it to move, gaining tempo and space while keeping the strong Ne5 and central pawns intact. Direct captures like Qxe4 fail to dxe4 recapturing the queen, so the safest and strongest practical move is to kick the knight with the pawn.
