Hans is hubris personified. He laughs when Levy Rozman's name appears. He mocks him repeatedly, even sneers at his title. A surplus of machismo. A big mouth and the talent to back it up. He gained more fame more quickly than Levy. Hans is one of the greatest living chess players, without question.
He chides himself, he shuts down his own feelings. He repeats lessons he has been taught, time and again.
The fear sets in. He repeats how painful this match is. He has been mocked before. Accused of cheating by the most popular player in the world, he was the laughing-stock of the internet for months. He most likely did cheat.
He becomes increasingly manic, saying how these things are supposed to go, how Levy is supposed to choke. He does not see himself or his opponent winning, but he imagines both of them losing.
He apologizes on auto-pilot, and clearly does not mean what he says. He says what lost him the game, then says he doesn't know why he knew he would lose, directly contradicting himself.
