Endgame improvement

GM Diamant - IM Robson (2009)

White to move. Is this a win, draw, or loss for White? What is the best continuation for White?

8/8/5k2/2P1N2R/3K4/pp6/8/r7 w - - 0 76

I remember this one well. One of the better endgame problems.

It looks to me like the best white can do is draw via 1. Nc4 - if 1...b2 2. N:a3 R:a3 3. Rh6+ K moves 4. Rb6 b2 5. Kc3 stops the pawn,

Black can also try 1...Rd1+ 2. Kc3 a2 3. Rh6+ K moves 4. Ra6 a1Q 5. R:a1 R:a1 6. Kb3 and I think this is a theoretical draw.
