Ya this spot is never fun as it always seems possible to rationalize a shove.  I think we will see JJ/QQ here a majority of the time, and I dont think we are seeing him folding this.  I also expect him to show up with something like AT here since he is IP.  I dont expect to see many Ax that are not turn boats.

I think we need to c/f though, an earlier poster was right in saying that we do have some miraculous random showdown value with KJ agasint hands like QJ and bad FDs, and I also just dont realistically see him folding any T or better, if he was I wouldnt mind a shove.

I think the turn is far from a standard 2 barrell(I still do it a lot but its not some auto bet), it really depends on your reads on villain, a lto of villains who col call here cna have an Ace, which is obviously bad for us, but those same villains could aslo have a lot of random FDs and random hands that you may get to fold.  I still think againt stations I just avoid trying to bluff them in bigger pots, as they lose so much value in the smaller pots.  I think I am most inclined to double here versus aggro/hero fish, as their flat call on flop is usally fairly weak.
