Its one of those JJ hands where its impossible to play right.
For me I think flatting his 4xiso is best given his stats, but I can also see why you raised, JJ is a strong hand 9 handed but when he 4bets you from MP his range has got to be AA KK QQ AKs and you kinda need to think how well am I doing against these hands on the flop.
But on the other hand I have played this hand this way many times and ended up folding to a Cbet.
Another reason why I hate JJ
