BTN is a 25/16 3bet 4%
isolate limp: 18%

BTN is a reg with that I mean he play regularly these games, his stats aren't std as you can see.

In this spot I levelled myself. I thought he would have a hand given he's tight and he isolated a short fish, but meh.

Is this a 3bet pre? What about the flop, if he bets we call and fold OTT if we don't spike a set?
I feel really lost here
