sample out

so the 'A' to '5' is straight, you maybe not read introduction carefully
but thanks for your help

in 131 I think Ace is biggest or smallest is not different ?

I have see article in here about 131..

They talk about straight-flush only in '10' to 'Ace', so I think I am not familiar about poker!
In my way to play poker straight-flush contain 2H 3H 4H 5H 6H ...
because that I maybe have some bug ...

My english is poor :-? I see 130 again and again but I just can not
understand how to simulate it, if you know, please tell me.
