Stated plan
Break through on the queenside with a4 to create an unstoppable passed pawn while the king holds g4.
Resolves to a2a4 · −1501cp
Reasoning
The queenside pawns form the classic breakthrough pattern a2/b4 vs a6/b5. Playing a4 forces a passed pawn: if bxa4 then b5 axb5 leaves the a-pawn passed and unstoppable, while the black king is tied to defending against Kxg4 and is far away on the h-file, unable to catch the runaway pawn. Meanwhile Kf4 continues to guard g4.
