<font color="#666666">1 fold</font>, <font color="#CC3333">MP raises to $0.4</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">Hero raises to $1.2</font>, BB calls $1.10, MP folds.

Hero checks, <font color="#CC3333">BB bets $0.5</font>, Hero??

As played do you have to fold to this weak bet?
