Q:B24 What is the counting strategy for Over/Under blackjack? A:B24 (Steve Jacobs) The card weights used for the Over/Under count are as follows: count +1 for Ace, 2, 3, and 4, and count -1 for tens and face cards. The deck becomes favorable for counts of +2 and above, and for counts -4 and below. Over-13 bets should be placed when the count is +3 and above. Under-13 bets should be placed when the count is -4 and below.

When playing Over/Under blackjack with this counting scheme, virtually all of the player's profit comes from the over-13 and under-13 side bets. This counting scheme is very poor for playing the blackjack portion of the bet, and will only allow the player to play about even with the house on the blackjack bets. However, the over/under bets can be very profitable if the game has good penetration. A 6-deck over/under game with good penetration can give the player an advantage of 1.5% or more. Single deck over/under games with good penetration (very rare) can give the player an edge of over 4% when using the over/under count.

No, as far as I know, there's no OU13 anywhere in Vegas. I think that some Atlantic City casinos still offer the game on a few tables, and it is still available in the Bahamas.

Last year, Bally's and Wild Wild West in AC both offered some side bets that included Over/Under. OU was actually the least profitable in the bunch though, and the games were burned out pretty quickly.
