Stated plan
Play the safe check Qg2+, exploiting the h3 pawn's protection to force the king into a worse square and continue the attack.
Resolves to f3g2 · −832cp
Reasoning
Black's queen on f3 is deep in White's camp. Direct checks like Qe2+ or Qxf2+ fail to Kxe2/Kxf2 since the queen would be undefended there. However, Qg2+ is different: the black pawn on h3 defends g2, so the White king cannot capture the queen. The king is forced to move (e1 or e2), since g1 is also covered by the queen and f2 is blocked by White's own pawn. This gives Black a powerful, safe check that seizes the initiative and keeps the attack going with tempo, which is clearly the strongest try in this position.
