Stated plan

Capture the d5 pawn with the knight, winning material after the ensuing trade sequence.

Reasoning

The knight on b4 is attacked by the a3 pawn, so it must move or capture something useful. Taking the d5 pawn wins material: after ...Nxd5, if Nc3xd5 then Bxd5 recaptures, leaving Black up a clean pawn while trades remain even otherwise.
