25... Kh7?
Black had probably predicted that his h-pawn would be lost, but he intended to penetrate to the-g-file. Although this plan turns out to be a mistake.
25... Rae8! would be better, with the idea of ...f6.

It's important to note that Ng5-e4 is a threat. It's worth Black's while occupying d5 and the knight is the best man for the job.

This was not a trick question and the simplest course of action is clearly the best. Black should pressure the c2-pawn and with ... b7-b5 as well as ...Bxc4 always available to budge the knight, Black's position should practically play itself! --- The game continued:

Mamedyarov beats Anand & Nakamura beats Dominguez to share 1st place after the rapid section of the St. Louis Rapid & Blitz!

"It was just a blackout" says Caruana about his blunder vs. Dominguez. His tournament hasn't been glorious after the first day, but he's well-placed before the blitz:
