Reads: <font color="blue">Villain 62/13/1.2 after 29 hands and has a habit of popping up multiple limpers from LP and the BB. Earlier I had to lay down pp 2's when I attempted to come in for 2xBB to build a pot if I hit my set, vary my raises and practice some pot control from studying NLTAP. Villain had reraised my 4xBB not long afer the pp 2's and on the very next hand I get AKs, raise 4xBB and villain goes AI.

I'm thinking what's my table image like now with him? Does he have an AI hand since he has't previously made this type of move? Is it another AK, and would he play AA/TT this way knowing I mucked to his earlier reraises?

Do you call or fold the AKs with these reads?</font>
