Book poker
1) In draw poker (high), the drawing of three cards.
"How many cards do you need?" "Gimme a book."
2) "The book" is a mythical set of instructions supposedly
containing
the poker wisdom of the ages. A player speaks of "playing
by the book," by which he means he is playing a hand the
way he thinks it is supposed to be played; such players usually
think "playing by the book" is equivalent to playing
tight. Actually, there is no book.
