villain is 10.4/8.3/1.0 around 50 hands. Should i fold to his checkraise easily in this spot?

Call. See what villain does on turn.... often enough villain checks turn here. A small bet on turn by villain is good too.

this one is tight with low aggression on flop.

I would dump it fairly quickly to this tighty.

Me too I hate paying off these fuckers - hes probably only calling PF with pairs and I doubt he CR you with 88 here especially given you raised UTG.

I might check his fold to cbet% and his CR flop% before i fold tho

Forgive this for sidetracking a bit... but what numbers would you be looking for on these that would suggest a fold is in order, particularly for the CR flop%? I'm a bit new to PT and still trying to get my bearings.
