Move All-in?

[easydoesit]

I play in a weekly tournament (with no rebuys) that usually consists of 7 regulars and 3 newcomers. There is one regular who always seems to raise too much like 4-500 (we start with 1500 chips)with the blinds at 25-50 or so, everyone folds and he shows a small pocket pair (I don't know why he shows). I've been debating if I should reraise him with anything higher than 10-J all in or just call and then move all in knowing that he will probably throw away his small pocket pair. What do you guys think is the best option?
