[kapw7]

Villain is 24/11/2 after 100 hands. This from datamining and no real reads (just joined the table).

Final Pot: 7.25 BB

I hate this kind of folds at 10/20 (BB defending-big pot- I hold AK) but 9[img]/images/graemlins/club.gif[/img] was one of the worst cards to fall (unfortunately villain knows that as well) and villain's stats look very solid.

What turn cards to you like or not like here and how would you play the rest of the hand for each group (of cards)?
