Stated plan

Play Qxe4+ to win the e4 pawn with check while also threatening the e1 rook, guaranteeing further material gain.

Resolves to c4e4 · −1314cp

Reasoning

The queen can capture the e4 pawn while delivering check via the e4-c2 diagonal, and simultaneously it attacks the rook on e1 along the e-file. White must respond to the check, but cannot save the rook, so this wins material.
