Wow, that's a tough one. Villain obviously has something and I hate thoughtless all-ins. Does the board give any clues to what he has? I mean if I have a boat (999JJ) and the board is JJ99 (I have 9 10), I'm gone.

Boats are obviously great hands, but they are sinkable. I hear bad beat stories at tournaments and most of them are some kind of "my boat was beaten by a bigger boat!"

In your case, this guy is in way to big of a hurry to get all of his chips in.
