Villain is 30/20 in 50 hands, seems solid.
Is this a good estimation for making decision while im playing.

Possible hands that beats me unless hes making a total move on me

KK, 99, flushdraw w AK, AQ, AJ, AT, KQ
less possible, QQ, JJ

Hands I beat AA, AK, KQs/o, TT

I guess raise/fold turn, check river would be best if I trust him a bit, would u raise/fold the turn here against unknown/pretty unknown? Or just a call down?
On the river theres no use raising my 2pair right?
