[akak]

First off, I hate the advice saying to limp in with JJ...

Now on to the hands.
Hand 1, pf is fine. On the flop, his less than .5x bet puts you in a weird spot. If it was bigger I'd say fold, but since it's so small, and since your hand is vulnerable to any ace or king I'd raise here. a psb sounds about right. from there it's hard to say since the hand would have played out differently.

as played, I'd fold the river. even though it's such a small bet, I don't think you're ahead 17% of the time. A big part of his range was AK and now you're behind that too.

Hand 2, fold pf. even more so since you only have ~50bb (poor implied odds). flop is close but I think you're ok calling. if you had a bigger stack it would be a definite call. lead for $2 on the river. you can't be sure he'll bet since he checked the turn.


as far as exploiting this guy goes, slowplay him more than you would someone else. let him do the betting. go for more check-raises.
