Episode 18 "Smoke and Mirrors" involves a chess game opening (1. e4, e5 2. Nf3, Nf6) where John says, "King's Gambit" when in reality this is the Petrov. Now I know it sounds cool when you are making a comparison from the game to someone of power taking a great risk, but when you are talking to chess players, get it right. We know that the King's Gambit is 1. e4, e5 2. f4 and it would be nice if the game were adequately represented in TV.
