Thanks everyone.
Mark articulated what I already knew - that I needed to shut down. When he called the 3bet I was wary and started thinking QQ, JJ, TT - even KK or AA since the original raiser was still to act. After the flop call, given that he had never called my CB before, it should have been crystal clear that I was behind.
This year, as I've read a lot of hand analysis on FCP, I've started to internalize estimating hand ranges, evaluating what has you beat, when to shut down. My leak is having the discipline to set aside the ego and just let the pot go. I hope this hand is a turning point for me. I was doing the correct analysis. I just didnt translate it into a smarter play.
Instead of shutting down and picking a better spot, I overbet and he called with...KJo for the straight.
The results-oriented part of me says KJ WFT!?!? The longer-term, make-good-decisions part of me wants to have this discussion, admit how I made the situation worse, and improve for next time.
I appreciate all the analysis and options for different lines on the hand.
Wow, sweet overcall with Kojak.
