Hikaru isn't the best at concealing his emotions because it's hard for him to master the poker face.

Like now, it's completely and totally obvious that he's pissed out of his mind. He's not doing so hot and by the deep analysis he's just done in his head, he's sure he will lose this match.

"Move," he commands under his breath, his annoyance with his opponent increasing by the second.
