I tried figuring out the best basic strategy in 9/7 Triple Double Bonus, and my code is still running! I wrote about the problem here:

I dont play video poker much and only Jacks or better when I do. But

Quote: blog

For example, 345 is on average better to hold than 55, 55 is better to hold than 789, 789 is on average better to hold than 77, and 77 is better to hold than 345.

Either I missed something, or it sounds like youre saying:
A > B, and
B > C, and
C > D, AND
D > A !

Um, really?

Yes, that's exactly what I'm saying. This also happens in other video poker paytables, but it's usually less than 15 hands participating in such loopy relations. 9/5 Triple Bonus Plus has a group of 12, for example, which I've written about here:

Could various penalty card combinations shift it that much?
May the cards fall in your favor.

I'm not sure I understand your question, but if you look at penalty cards, you can find an exact rule. For example, in the Dancer/Daily notation, this is what I have found for 9/7 Triple Bonus:
[...]
SF3 +1; SF3 +0 ... (SF3 0hi 0i < 55TT when sp)
............................ (JT8, J98 < 77) (QT9 < 88)
low pair: 55TT
[...]

It's being restricted to basic strategies that makes the problem complicated.

Ahh, sorry. I thought you were working on a more complex strategy.

15 wheels doesn't terribly surprise me... I take it you're basing your EV comparisons on simulation results?

I have created a computer perfect strategy for the game too, penalty cards and all. But interestingly, that was easier to come by. Figuring out the basic strategy with the highest return is a much harder problem.

No. I'm doing exact math. Video Poker is simple enough, one can calculate the exact probability.

My software finished running, and now I have the "best" basic strategy for 9/7 Triple Double. I wrote about it here:

Can you explain it like Im five - I hope you dont get sued by reddit

The hierarchy of the entire tree is obvious but is 789s priority higher than 456s?
8TJ greater than 89J?

Or are their levels equal in priority if I I encounter these situations?

They are not comparable, because you can't encounter such situations. If a hand contains both suited 456 and suited 789, it needs to have six or more cards. If a hand contains both suited 89J and suited 8TJ, it must also contain the 4-card straight flush option 89TJ, which is better to hold than a 3-card straight flush. Does that make sense?

It is an intriguing writeup, and the graphics are nice, too.

Very good stuff, FiliusBruce.
