Holdem probability question

Hi!
I found the sitea few days ago as I'm looking for a couple of probability questions with regards to Texas Holdem. The page 'Ask the Wizard' is asking to proceed to this forum for placing such questions. But this is a so big forum that I'm lost here.
Could you please indicate what sub-forum is the best to place such strict mathematical questions.
Thank you!

Thanks a lot! appreciate it!
