1. Villain is unknown but over the small sample he seems to have regularish stats playing 20/20 with folding to the only 3bet prior in his 60ish hands. I don't really see any value by betting no the turn and it seems like he'll be raising even AK which makes me suck at life.

2. Villain is an unknown and I still have no idea how to get value in these situations. Fuck it I'm guessing bet a shitload bigger on the turn but should I ever bet the flop vs. an unknown?
