Hero calls $0.10, MP calls $0.10, <font color="#666666">1 fold</font>, <font color="#CC3333">SB raises to $0.3</font>, <font color="#CC3333">BB raises to $1.9</font>, <font color="#CC3333">

Hero : Push or call? Actually I don't know what I wants to do. I don't know if I wants to isolate by pusing, or keeping the SB in the pot too. What about a very small reraise to 4-5$, which pretty much commit us all to the pot, and the possibily of SB calling is bigger than if he pushed.
