I was playing a Spanish 21 game with a $1 progressive jackpot. I was ignoring the side bets. Then, I got a pair of Aces v. a dealer Ace. And, the dealer had an Ace down! The progressive jackpot was more than $9,000. So, it got me considering, at some point that $1 jackpot is +EV. There is a one hundred% payout for 4-of-a-kind (your very first two cards match the dealer’s first two cards). There are smaller sized payouts as effectively. Just pondering about the one hundred% payout on four-of-a-kind, at what point is that +EV for a $1 bet?
