A recent proliferation of the Blackjack +3 Card Poker (side bet) games at my local store has me wondering. I'm sure the +3 is a sucker bet, since they've made this bet available at 80% of the BJ tables, but how bad is it. The side bet pays 9/1. Is there a known frequency of being dealt a winning 3-card poker hand. I know it's fun to win a 9/1 payoff, but I don't play it. Alas, once hit the 3-card four times in a row.
