The only poker hand in the two-card hand is a pair or no pair, after which the individual cards determine the value. The high hand must be of higher poker value than the low hand. Some casinos have dropped this ridiculous rule, but most still cling to it.
After the player makes a bet, the dealer will deal the player and himself seven cards each.
It may be used as an ace, or to complete a straight, flush, or straight flush, or royal flush.
