Stated plan

Sacrifice the rook on e3 to win material via a forced recapture sequence, ending with the queen safely capturing on e3 up a piece.

Reasoning

Black's rook on e7 can capture the knight on e3. After ...Rxe3, White's only recapture is Rg3xe3 (the d3-pawn cannot capture backward, and nothing else defends e3). Then Qf2xe3 recaptures the rook safely, since e3 is undefended by anything else. Net result: Black trades a rook for a knight+rook, winning a full piece, while also centralizing the queen with strong threats (hitting the g1 rook along the diagonal).
