I don't think his range is as strong as you give him credit for, unless you think he's a nit. If he's a good player then he should have a bit of a wider range since he's CL and he should be raising a lot of hands that block rejamming ranges i.e. unsuited broadways.
Do you know what your table image is, or what this player thinks of you?
Standard play is to 3bet and get it in if he 4bets. I know it sucks to call off cuz I don't think he has JJ here too often (again, depends on your table image), but you're 3bet folding too much equity here.
You're passing up on too many chips to not 3bet because 1) he can fold, 2) he can call your 3bet and play postflop with a range disadvantage OOP and 3) you're doing well enough against him. ICM is a factor but I think you can't be too afraid to clash with a big stack when you'll have such a higher likelihood of taking down the tourney if you double at this point.
