The point here is a good evaluation. Back to the original position: [D]5rk1/1pp3p1/p1p5/7p/6P1/4b3/PPP2RPP/5RK1 b - - You first notice the pin at f2 so that rook can't move. The one at f1 is tied to its place to defend the rook. And so is the king. So all white pieces can't move. And black has a loose king to do whatever he wants. If white doesn't manage to get rid of the pin he's dead. That's a big minus score for eval and you're done, that should find pretty easily h4 followed by h3. I think this is feasible.
