This was on 10NL Bodog, so I'll have to reconstruct the hand as best I can:
Stacks:
Me (BB) ~$10
Villain (button)~$10
I'm dealt Jc9c in BB.
4 limp in, I check.
Pot $0.50
Flop:
3cTc8h
SB checks, I bet $0.40. 1 fold, CO calls, button raises to $1.90. SB folds.
How much do you reraise here? Just push since I'm going to be investing most of my stack on this street and the next and hope he calls?
