It really depends on the player but its a fold to a lot of players. I think he's only doing that with a 10 or a str8. There isn't a good reason to do that with an overpair because you mightve caught trips. He did raise pre and thats when you need to put him on a range. Does he raise often, does he ever limp, etc... to find out if he would be raising with a j10 or something. But I guess you made a good call. Even if he was somehow ahead, you have some outs.
