I like the show, but, like most big budget shows and movies, the writers and directors just can't be bothered to get the little things right. I was just watching an episode where two FBI agents were discussing the villains chess games. One of them says, "He used the queen sacrifice -- one of the most powerful moves in the game." Well, that was bad enough -- as if "the queen sacrifice" was the name for a particular move, rather than a whole class of moves. But it got worse -- on the computer the agents were watching, the showed the move -- and it wasn't a queen sacrifice!
