Endgame Armageddon of Black

This is the original position from which ONLY ONE unstoppable "Breakthrough Combination" yields a certain victory for White. 

    This position demonstrates the power of pawns (their strength and weakness) - which shines so well in endgames.                                                 

The key is for White to have his pawns in "Battle Array" (alongsude on one rank) facing the weakened Black pawn structure (due to doubled g-pawns).
