White will have to play boldly against the king. If the white
attack fizzles out then typically the defender is left with extra
material in these type of positions.

Did you play a game from this position against the computer? How did the
game continue if so? I think the computer would need a 40/2 time control
to defend this as black as it might start grabbing Queen side pawns.

Rebel 8 on a quick analysis plays Qd4 Rad1 Qc5 with a plus score
for black. But like you said if that h pawn could start moving then
the game would get interesting.
