Each player receives three cards face down. He arranges them in any order desired, but may not thereafter change the order. There is a betting interval. Then each player receives four face-up cards, one at a time, with a betting interval after each.
Next, each player turns up his first face-down card, followed by a betting interval, and then his second face-down card, followed by the final betting interval.
The last card is then turned up for the showdown.
