>Dominguez cant win the a pawn after 29.h3 Ra4 30.Nc6 Rxa4 31.Rd4

I guess was (Ra3 instead of 29...Ra4), your analysis is wrong because after
31.Rd4 black can simple play 31..a5! and the bishop is now protected by the pawn
also. I think that the plan for white should be atacking in the king side
looking for the f pawn (rook in seven + knight).. you should notice that after
31..a5 black can move his rook and let white win the pawn back, then 3 vs 4 (in
the same side-kingside this case-) rook ending is a easy draw, ask Karpov and
Kortchnnoi :)  However only white can win this, is black who need to play good
for the draw....
