Stated plan
Play Qf5+ to exploit the exposed white king, forcing a weakening response and opening follow-up tactics.
Resolves to e4f5 · lost a forced mate
Reasoning
The white king on h3 is dangerously exposed. Black's queen can jump to f5, delivering check along the f5-g4-h3 diagonal since that diagonal is currently open. White is forced to react (blocking with g3-g4 or moving the king), which further weakens the king's shelter and, notably, after g3-g4 the pawn on f4 loses its defender, allowing Black to pick up material and continue the attack with tempo.
