First of all, 6.Nh4 is a very strange move. Was Noonian playing with a book?
6.Nbd2 is the most common move here, although admittedly it tends to do better
for Black. c3, b3 and h3 also seem playable.
Then, Chessmaster 9000 (SKR personality), prefers 37.Be5 to Noonian's Raf1. Be5
gets an eval of about 0.15 in White's favor, while Raf1 gets about -0.30 (after
37...Bd4 38.Be3 Bxe3 39.Rxe3 Rb2 40.Rf6+). In this position, the game looks
pretty drawish.
So I think 38.h4 is the killer. As I said above, The King evaluates 38.Be3 at
about -0.30, but after forcing a few moves, the eval gets closer to a draw.
After 38.h4, the eval is about -0.90. So that's two consecutive moves that both
drop about a half-pawn in eval. And I don't see any recovery from then on in the
game.
