poker face

"If you're playing a poker game and you look around the table and and can't tell who the sucker is, it's you."

Paul Newman

"There are few things that are so unpardonably neglected in our country as poker. The upper class knows very little about it. Now and then you find ambassadors who have sort of a general knowledge of the game, but the ignorance of the people is fearful. Why, I have known clergymen, good men, kind-hearted, liberal, sincere and all that, who did not know the meaning of a flush. It is enough to make one ashamed of the species."

Mark Twain
