67.38. Once the cards have been distributed, the dealer compares each player’s card with his:
(1)  if the player’s card is of higher rank than that of the dealer, the initial wager is a winning wager and is paid 1 to 1;
(2)  if the player’s card is of lower rank than that of the dealer, he loses his initial wager;
(3)  if the player’s card is of equal rank to that of the dealer, the player may either withdraw from the game, losing half of his initial wager, or he may opt for War.
