I didn't know what to make of this microbet. I knew I wanted the pot larger but I didn't want to push him out, so I made a small raise I thought he would have to call.

SB checks, Chris bets $3</font>, SB raises to $6</font>, Chris calls $3.

Normally I would instantly 3-bet here, but I've become shell-shocked from a terrible month of long shots hitting and me paying them off. J-10 is certianly in his range, so I make the weak play and call, hoping the river pairs the board.

River: ($16.25) K (2 players)</font>
SB bets 27.32 putting me all in.

I think there are 3 possibilities,
1) He's shoving with the straight
2) He has trip kings
3) He has kings full, he check-raised the turn with two pair, most likely K,5.

Odds are 1.6-1, so I need 38% to break even.

Do you call?
