Stated plan
Sacrifice the knight on c3 to deflect the queen and open the d-file for a favorable exchange sequence that nets material.
Reasoning
The knight on d5 can jump into c3, grabbing a pawn while attacking the b5 and e4 pawns. White's queen must recapture (Qxc3), but this removes the defender of d4, so Black plays Rxd4 (protected by Qf6). If White trades on d4, Black recaptures with the queen, coming out ahead in material after the dust settles (knight+rook given up for two pawns+queen, netting Black a clear material advantage). This sequence starts with the knight capture on c3.
