Nitty and Weird

Villain is a bit of an unpredictable aggro reg (25/21/14) who plays higher quite a bit. In my experience he folds a bit too much facing heavy heat. I think he thinks I'm nitty (he's showed me a few big folds in the past).

I 3b this about 90% of the time but was looking to keep the SB fish in the hand pre. Wtf is going on here?

Genitruc

This is a pretty tough spot. Does he cbet AQ/AK etc. Would he ever c/c those hands instead of c/r?

It sucks cause now I think all of his bluffs will continue on this card.

big prob is having no idea what his flop CR range is on this board!

I'd say he's more inclined to check flop with ace high hands that have showdown value rather than with worse hands so the river could have hit him, although I'm not sure he would jam a bare top pair here against you.
