I made this hand today online. What are the odds of making any seven card straight flush.
I believe it is between approx. 1 in 9,000,000 and 1 in 15,000,000, depending on whether the first card is towards the middle ranked cards or at the end (2 or K). If the first card is a 7 then you can have A-7, 2-8, 3-9, 4-T, 5-J, 6-Q, 7-K. if a 2 or a K then you can have on two options A-7, 2-8 or 7-K, 8-A.
Here is my approximate calculation for the first card being a 7. I don't think this is correct, but it is not a million miles away.
Would love someone smarter than me to tell me the correct answer!
