23 suited

[King High]

Live muti 8 handed I am statrting to amass chips and have a very stong Image due to some great cards I raised with and got called down with. Most at the table are bad and don't have more than the basics down.

I have now started to steal a bit I am in late with 23d I raise 3.5x the bb and to my surprise the button sb bb call. Damm!

Flop is Kc3cKh.

sb checks bb bets the min 200(pot 2800) I raise to 600. button fols sb fold bb thinks almost mucks 2 or 3 times calls. Next card is a brick. BB checks I check (I now think was a big mistake).

River brick he checks I check.

Lets hear it. I get back to you with the results.
I think this could have been played several ways looking for what is the optimal.

thanks
