Stated plan

Play Qe7+ to force the king to d5, maintaining a powerful mating attack while neutralizing Black's counterplay.

Resolves to d8e7 · −0cp

Reasoning

The black king on e6 is quite confined, with pawn d6 and rook e1 nearby. Playing Qd8-e7+ gives check while being protected by the rook on e1 (along the e-file), so the king cannot capture the queen. All flight squares except d5 are covered (d6, d7, e5, f6, f7 are all controlled by the queen), forcing ...Kd5. This is a strong forcing move that seizes the initiative and disrupts Black's own threats (like ...Qxf2+), while keeping the black king trapped in the center for a follow-up attack.
