<font color="black"> I should raise a little more preflop, I know. I was wondering if it is profitable to c bet in this spot against shorties? They just joined the table, no reads, but shortstacks are known to stack on any pair so there is a possibility that with two of them, someone will push and I will have to call with my overcards+gutshot.</font>
