Question for Riverboatking

[Garland]

I was reviewing one of your past hands, and I was hoping to get your thought process. I'll give the action, but not the opponent's cards or results so others can follow along. Anyway, I appreciate if you can share what's going in your head as I was quite baffled. Any insight you have is appreciated.

Thanks,

Garland
