JJ overpair from SB - line check

Table is very loose and I don't think I can isolate PF from the SB without pretty much open pushing PF. $2 PFRs aren't getting any respect and a typical flop is 3-4 way. I have been getting absolute shite cards so my table image is probably tight, in case it matters.

Only read on the opps is on MP3 who is a "tricky" player - overuses weak checkraise.

Perfect.
