<font color="#666666">1 fold</font>, MP1 calls t100, MP2 calls t100, CO calls t100, <font color="#666666">2 folds</font>, <font color="#CC3333">Hero raises to t1690.</font>

<font color="black">My reads were that the limpers played way too many hands like many of the bad players at the $6.50 level. I didn't think they had anything here...they would have raised with a good hand.

Is this play too aggressive? Should I just check here and play for set value? </font>
