It was clear yesterday that Dominguez would play the ending for a win; he was a pawn up and the state of the match warranted it. But I was getting a hunch that Radjabov was also trying to confuse the issues; perhaps hoping that Dominguez would go astray. Radja turned down repetition of positions a couple of times and went on several fishing expeditions instead. But that made no chessical sense; there was not a chessical thing White should have been fishing for, besides a draw. Dominguez could have easily afford to loose a pawn, two, perhaps even all three and still hold the position. So the next hypothesis was that Radja was "messing with Dominguez' mind"; that Radja was fishing for something that would unsettle Dominguez. Eventually, this prompted my comment that "... these guys are crazy ..." The analogy I did not find yesterday was that much of that end-game felt like a boxing stear-down: as if it was not about who is a better chess player; but rather about who is the macho supremo. I am not sure how much Dominguez was realy playing that game, but I give it a high probability that Radja was.

You countered that "even though this should be a theoretical draw, Dominguez had the right to press on". (Btw, I have no beef with that.) Since I did not want to go into long explanations of thoughts that were even fuzzier yesterday, I just pointed to the place where I was with my thoughts.
