50NL 6m: KK on a coordinated flop, bet, raise, reraise???

[Jigsaws]

SB is an alrightish regular, but his donk into me doesn't mean he has more than a pair, or maybe pair+OESD.

CO has just sat down is unknown.

I can fold here, right?

PokerStars No-Limit Hold'em, $0.50 BB (6 handed)

Hero ($88.30)
MP ($58.95)
CO ($42.45)
Button ($47.25)
SB ($54.35)
BB ($25)

Preflop: Hero is UTG with K/images/graemlins/club.gif, K/images/graemlins/diamond.gif.
<font color="#CC3333">Hero raises to $2</font>, <font color="#666666">1 fold</font>, CO calls $2, <font color="#666666">1 fold</font>, SB calls $1.75, BB calls $1.50.

Flop: ($8) 8/images/graemlins/diamond.gif, J/images/graemlins/club.gif, 9/images/graemlins/heart.gif <font color="#0000FF">(4 players)</font>
<font color="#CC3333">SB bets $4</font>, BB folds, <font color="#CC3333">Hero raises to $12</font>, <font color="#CC3333">CO raises to $20</font>, SB folds, Hero folds?

Yeah...folding here for $8 in this pot sucks, but I can't even imagine you being ahead.

i'd raise more on the flop, make it ~$16, i'd fold to CO's reraise, at the very worst he has AJ, but could easily be straight, 2pair/set. Without reads i def fold kk here. i think your behind his range.

[xwillience]

what the hell happened to SB? did he fold to the 3bet? yeah you can fold probably. if SB called, i would peal to see if i improved. another K or maybe an 8?

[Jigsaws]

SB folded. Edited the OP.

[Shaddux]

I hate folding KK on this board, but we have no reads on CO, and he basically defined his hand.

[ActionStan]

Weird bet. A set makes sense here, but all of the 2pr and str8 hands are a little dicey to call a pre-flop raise with. I'd expect a set or a draw to bet more with all of the draws. It's a cheap call, but I wouldn't know what to do with the turn. I'd lean towards calling and leading the turn on a blank, but wouldn't begrudge a fold if it feels like some sort of trap from this player.

Looks like at least a set or 2 pair? But you only have to call $8 into a $44 pot though. Call and re-evaluate?

[Jigsaws]

I think flat-calling here really sucks. He's shoving the turn almost always, don't you think?

[Thrahl]

This line is a draw like never. Weak lead + mini 4 bet = monster. Fold.

This is a really ugly spot. I can't see you being ahead and yet the pot odds are amazing. But the long and short of it is that you are definitely behind and you have no FE.

Fold =(

[Jigsaws]

Okay... so I shoved and lost to QT.
