Stated plan

Advance h5-h6 to break open the black king's shelter and launch a mating attack.

Resolves to h5h6 · lost a forced mate

Reasoning

Black king is trapped on h7 with pawns on g7. Pushing h5-h6 forces further weakening: if gxh6, then g5-g6+ drives the king into a mating net supported by White's king and rook, while ignoring this leads to hxg7 with a passed pawn storm. This creates the fastest decisive attack.
