This is the game in which you can open on anything and in each turn you must bet or drop ("pass and out"). In each turn you must at least chip along, where in a jackpots game you could check free.
Much depends on the relative value of a white chip (the chip of lowest value; it may be blue). Some players make the white chip of nominal value only—say ten cents, when the limit is $1 before the draw and $2 after, and when the white chip is seldom bet except for perfunctory purposes. From such games came the entire present custom of checking free; the "white check" was worth so little that it seemed hardly worth while to keep a stack of them and bother to put them in.
