Hero checks, UTG+1 checks, UTG+2 checks, MP2 checks, CO checks.

<font color="#0000ff">With so many people seeing this flop, I think I can checkraise Kx behind me most of the time. Bummer, no bets.</font>

Turn: (t82.50) J[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(5 players)</font>
<font color="#CC3333">Hero bets t85</font>, UTG+1 folds, UTG+2 folds, MP2 folds, CO calls t85.

<font color="#0000ff">Okay, no more hanky panky. Bet the pot and take it down. Oh, a call. I think I'm still ahead most of the time as I can see Kx or a J calling now.</font>

<font color="#CC3333">Hero bets t175</font>, <font color="#CC3333">CO raises to t350</font>, Hero folds.

<font color="#0000cc">I don't need to bust with low two pair. I think I can bet this for value here. I feel like the river raise tells me I'm beat. Do I need to call here now and twice on Tuesday? Or do I resign and play with a still-alive ~500 chip stack?</font>

I might check-call or check-fold the river depending on how much villain bets. Maybe lead out on the flop but I see your point.

I think I would probably call this. I think sometimes this is a slowplayed King and with the pot odds you are getting you dont need to win every time to make the call correct. Just my 2 cents though id take my advice with a grain of salt as I am new to sit and goes.

Lead out on the flop. With no PF raise there is no reason to think that someone will bet here. On the river, CO has QJ or T9 (I think). Good fold.
