Full text
21.1. Provided that it is so indicated at the table, the player can, in addition to the initial wager governed by section 17 and before the dealer announces “No more bets”, place a supplemental wager which wins if the total value of his first 2 cards is from 12 to 16. The supplemental wager cannot be for an amount greater than his initial wager. A winning supplemental wager is paid at even money unless his first 2 cards are 2 aces or 2 eights, in which case it is paid 2 to 1.
