Six cards dealt. After the first betting round, each player draws as per normal Draw game rules. The exception is that each player draws one less card than they discard. This means that if a player wants three new cards, he is going to have to discard four cards out of his hand. If a player wants to discard three cards, then he is only going to get two cards back.
With each player drawing one less card than he or she receives, every player will now have a five card hand. A final betting round ensues and the best five card hand wins. This allows players to get better hands and hopefully, stay in longer, compensating for only two betting rounds.
