I normally avoid hands like these where I have to make a big call without being very sure Im ahead, but based on your descrpition of him, I call this one.
There are quite alot of hands where a LAG might go all in here, especially if he keeps making huge all in overbets. He could easily have
[Jd]. Even if he has 2 pair, you're even money.
I suggest sitting on the other side of him next time.
