1. Players are dealt five cards face down into their hand.

2. Four community cards are dealt face up in the center of the table in two sets of two as shown below.

3. Players may use one of the two sets of community cards in their hand.

4. Players have a chance to exchange one card. The replacement card is dealt face up and stays face up in front of them, but is still used in "their hand". 

5. If a replacment card dealt to a player is the same poker rank of any of community cards, that community card is replaced with a new card dealt face up from the top of the deck. If more than one card matches, all cards are replaced. Only community cards are replaced as a result of the matching.

6. Players may exchange one card from their hand including any cards face up in front of them. Replacement cards are dealt face up as previously with the same consequences.

7. Players are then given one final chance to exchange one card in the same manner with the same possible consequences.

STAY/FOLD and the rest of the hand proceeds and usual.
