Stated plan

Capture the undefended knight on c6 with the queen, winning material safely.

Reasoning

The knight on c6 is undefended, and White's queen on d7 can capture it safely (no black piece can recapture, since e8-rook and pawns don't defend c6). This wins a piece cleanly without allowing any dangerous counterplay from Black's bishop or rooks.
