This is the second post where I've seen you post your actions then try to defend everything you did in rebuttals to specific posts.

For me, I need to define my hand right now. I bet out. If the CO calls, he's probably on a K, maybe the flush draw. If the SB check-raises or check-calls, then I know where I am and what I need to get ahead.

I think here, with the overcard on the board, check-calling or check-raising is a mistake. A semi-bluff makes a lot more sense for me.
