Stated plan

Force the trade on g5 to expose the black kingside pawns to the white king, winning material.

Reasoning

Black's g5/h6 pawns are only loosely connected: after 1.hxg5 hxg5 (forced, else White simply keeps the extra pawn) the resulting pawn on g5 is no longer defended by f4 (which only guards e3/g3), so White's king simply scoops it up with Kxg5, and then even grabs f4 next, since f4 becomes undefended too. This wins material with an already dominant king.
