Blackjack Super Sevens
Author: admin
This side bet was invented by the same man who invented the over/ under bet; essentially, you place a one-dollar side-bet that you will be dealt one, two, or three sevens, with various payouts depending on whether the sevens are suited or unsuited. Technically, card counters can beat this option if they learn to keep a count of the sevens, and the perfect counting system for this option is to count all sevens as -12, and everything else as +1.
The house edge on the Super Sevens option is about 10.8%. This qualifies it as a true sucker bet, one of the worst bets available on a table game, similar to the house edge on the hardways bets at craps, or the tie bet at baccarat.
I no longer remember the true count at which it makes sense to place a Super Sevens bet, but it does occur occasionally. Even so, I wouldn't waste my time trying to figure it out. The problem is that the option is not worth more than a few cents per hour to a seven-counter, due to that $1 maximum bet restriction. And since the counting system has virtually no value whatsoever to your regular blackjack hand, why spend even a moment learning it? Without the seven-count, the house has about an 11 % advantage over you on this bet, so it's yet another side-bet with no value to anyone. (Well, actually, it has some value to the casinos that offer it, since they keep eleven cents for every buck wagered!)
NOTE:
Some casinos offer special bonus payouts for player hands that contain three 7s, most commonly a 3 to 2 payout if the hand wins. This is not the same thing as the Super Sevens option, which requires the player to make a separate side-bet. The values of bonus hands, such as 777 pays 3 to 2, or 678 suited pays 2 to 1, are listed in the chart of rule effects in Chapter Eleven.

One of the more popular options (unfortunately not popular enough!) is the over/under bet. This is an optional side bet (actually two separate bets) that your first two cards will total either over or under 13. There is a special area on the table for you to make these bets. Aces always count as 1 for this bet, and a total of 13 always loses. If you win on an over/under bet, you are paid 2 to 1.
This rule is most often offered on 6 and 8-deck games, and it has little value with a traditional card counting system. Using the Hi-Lo Lite, you would need a true edge of +2 1/2 to just break even on the over bet, or -3 on the under. These advantages will not occur very often in shoe games, unless the penetration is quite deep.
Abetter counting system for this option is to count the ten-valued cards as -1 and Aces, 2s, 3s, and 4s as +1. Using this counting system, you would make an over bet at a true edge of+1 1/2 or greater, and an under bet at -2 or lower. This greatly increases the value of the option. If you know the Hi-Lo Lite indices, you may use the Hi-Lo strategy changes with the over/ under count for strategy plays on your blackjack hand. In a 6-deck game, with 75% penetration, you could get close to a 1% advantage by using a 1 to 4 spread with proper over/under bets. With deeper penetration, the value skyrockets.
In some European casinos, there is an over/under variation in which a pair of aces pays a 7 to 1 bonus on under bets. This payout almost doubles the value of the over/under option. Unfortunately, there are very few over/ under games anymore, and the casinos know that card counters attack them.
Most casinos that offer the over/under bet limit the amount that can be bet on this option. In many cases, this bet limitation, in conjunction with generally poor penetration, makes the over/under bet pretty worthless.
By the way, do not place over/under bets without using a card counting system. The house advantage is 6 1/2% on the over bet, and more than 10% on the under, if you're just guessing.
