Can black survive?

there is a problem with the line of rooperi and one of MrComposer, if black makes a queen then white would make other one with check first and after that would take the queen with the rook, like boren10's line

 

yep but what if the king doesn't go to the c column, or if he chooses not to take the pawn, would you stop the g pawn with the rook?, this is what would happen
 

Like I said, I wasn't convinced earlier about 2 Kb3...

Well clearly 6...Kf7 loses, so no need showing it.

Try 6...Rc8+ 7.Kxd4 c2.  Still, looks a bit dangerous for black, but he's trying.

Hey, that line looks familiar... 

I think the king would'nt take on d4 i think he would go to d3, and this is what would happen:

The rook's activity is more valuable than the king's.  It's not good form to blockade with the rook like that.

But yeah, black doesn't have to take.

i think black can survive in all variations these with 2.KD3

variations with 2. Kb1

variations with 2. kc1

variations with 2. Kd1

variations with 2. Kb3!

Ah, black still winning seeing all of the analyzes. 

Black can escape: hxg6 hxg6 Rf2+

Lots of times I've been sure that I'll lose a game, but then my opponent makes a mistake and the tables turn. I that's rarer with highly rated players.

but is like if something is not ok for black, maybe something i haven't seen
