Stated plan
Play Nxe6 to fork the queen on d8 and the undefended bishop on c5, winning material.
Resolves to d4e6 · lost a forced mate
Reasoning
The knight on d4, while attacked by the bishop on c5, actually has a powerful jump: Nxe6! This captures a pawn and forks the queen on d8 and the undefended bishop on c5 (the knight on e6 attacks both d8 and c5). The e6 square is not defended by any black piece, so the knight is safe there. Black must move the queen to avoid losing it, after which White simply plays Nxc5, winning a full piece plus a pawn for free.
