We need to calculate how many possible five-card boards there are, and how many of those contain both of the black sevens. Let’s assume I don’t care whether they come on the flop, the turn, or the river, so that we can ignore the possible orders in which the cards come.

Among the board of five community cards, the 7 ♣ and 7 ♠ will need to appear. (Most promotions of this type exist only for Texas hold’em.) What is the probability of this happening? In order to claim the bonus, you’ll need to start with a pocket pair and have the other two cards of that rank appear among the five community cards. The amount might be fixed, might be determined by spinning a wheel, or might climb every day until somebody claims the bonus and then it gets reset to a baseline. Typically if you have four of a kind or a straight flush or royal flush, using both hole cards, you win some cash. Perhaps the most common promotion, at least in the Las Vegas card rooms, is a high-hand bonus.

That’s what I’d like to start addressing in this article. That guide, however, does not discuss how the presence of a promotion changes the dynamics of the poker game, and how one should alter strategy accordingly. I wrote for PokerNews a basic, introductory guide to the operation and rules of the most common types of promotions here.

Low-stakes poker players in casinos love promotions, which allow them, if luck is on their side, to take home a lot more money than they could expect to win through straight poker.
