Reads: <font color="blue">New at this table so no reads or stats. Only scared of a 7 obviously by the MR - fold flop maybe?

On the turn he is betting weak so it makes me think he may not have a 7. River is even weaker so I have to call it, does a raise have any merit - dont think he would call this without a 7 right?)</font>
