Super Double Bonus is a version of Double Bonus where four jacks, queens, and kings earn 600 coins instead of 250 and the straight flush returns 400 instead of 250. The best-paying version, which returns 45 for the full house and 25 for the flush, returns 99.695% when played well. When combined with a decent slot club and/or set of promotions, this can be a profitable game to play when you find it.
One of the trickiest parts of the strategy is when you are dealt an ace of one suit and a “JT” of another. Depending on the other two cards, sometimes you hold the “JT”, sometimes you hold the ace by itself, and sometimes you hold AJ.
For me to learn this, I created a flow chart which I believe is 100% accurate in this area of the strategy chart — although it presumes you know that a 4-card open-ended straight and a 3-card straight flush with one high card and two insides are both more valuable than the options presented in the flow chart. It follows relatively simple logic — but even relatively simple logic requires more concentration and study than some of my readers wish to endure.
What I thought I’d do is to present my flow chart, give you some sample hands to play, and let you see how you do. Afterwards, I’ll go through the flow chart more slowly and maybe it will be easier to understand.
And if you’re not in the mood for the logic of 9-5 SDB, it’s okay with me if you always play “JT” when you come to these hands. You won’t be giving up a whole lot. For some folks, making these kinds of distinctions cause their heads to hurt. If that’s you, take this column off and come back next week.
A versus “JT”:
Is there a flush penalty to the “JT”?
If no, play “JT” — end
If yes, continue
Is the flush penalty to the “JT” a 2-6 and the fifth card suited with the A?
If yes, is it an 8 or 9?
If yes, play AJ — end
If no, play “JT” — end
If no, continue
Is the flush penalty to the ”JT” a 2-5 and the fifth card an 8 or 9?
If yes, play A — end
If no, play “JT” — end
Is the flush penalty to the ”JT” a 6 and the fifth card a 7, 8 or 9?
If yes, play A — end
If no, play “JT” — end
Using the above logic, play these hands:
- A♠ J♥ T♥ 2♠ 5♠
- A♠ J♥ T♥ 9♠ 7♦
- A♠ J♥ T♥ 9♠ 8♥
- A♠ J♥ T♥ 3♣ 7♥
- A♠ J♥ T♥ 9♣ 5♥
- A♠ J♥ T♥ 7♣ 6♥
- A♠ J♥ T♥ 7♣ 5♥
- A♠ J♥ T♥ 8♣ 2♥
- A♠ J♥ T♥ 8♠ 2♥
- A♠ J♥ T♥ 7♠ 6♥
Here are the answers. If you easily got them all correct, you don’t need to read any further:
- A♠ 2♠ 5♠
- J♥ T♥
- J♥ T♥ 9♠ 8♥
- J♥ T♥ 7♥
- A♠
- A♠
- J♥ T♥
- A♠
- A♠ J♥
- J♥ T♥
If you missed one or more of the above problems, the following explanations may help:
Is there a flush penalty to the “JT”?
If no, play “JT” — end
If yes, continue
This rule is the easiest. Just look for a card suited with the “JT”. If you don’t find one, then “JT” is the play — unless, of course, some higher-ranking combination is in the hand.
Is the flush penalty to the “JT” a 2-6 and the fifth card suited with the A?
If yes, is it an 8 or 9?
If yes, play AJ — end
If no, play “JT” — end
If no, continue
We only get to this rule if there is a flush penalty to the “JT” and also a flush penalty to the A. Also, this is the only time we can hold AJ. Notice that the flush penalty to the J cannot be a 7 or higher as that would make it a higher-ranking 3-card straight flush or 3-card royal flush. Also note that this says that if there is a flush penalty to the A, but it is not an 8 or 9, we hold the “JT”.
Is the flush penalty to the ”JT” a 2-5 and the fifth card an 8 or 9?
If yes, play A — end
If no, play “JT” — end
By the time we get here, there is no flush penalty to the ace.
Is the flush penalty to the ”JT” a 6 and the fifth card a 7, 8 or 9?
If yes, play A — end
If no, play “JT” — end
By the time we get here, there is no flush penalty to the ace. The only difference in the last two rules is when the fifth card is a 7. If the flush penalty to the J is a 6 (meaning it is not a straight penalty to the A), we hold the A by itself. If the flush penalty to the J is a 2-5 (which are all straight penalties to the A), we hold the J.
