Perhaps I am being naive but as I see it, he's either a massive favourite with a higher pair or only a slight dog with two overcards. I think the 6k raise is too much in that position becaiuse of the lack of info and, unless Villan is a complete idiot, he's got to be putting you on good cards to re-raise in early position. I wouldn't want to kiss goodbye to the chips and the pot odds are good, but I'd figure it was the wrong call. Whether I made would depend on the consequences to my table image, how long the table had been together etc. The call leaves me with an above average stack but it's, most likely, going to make subsequent aggression less profitable if everyone sees I've re-raised and then called a further re-raise with 66 in early. Of course, if you win, then it makes people very wary that you'll bet hard on such poor holdings but chances are you're losing.
I'm quite a successful MTT player but not at this level so please tell me if I'm being naive here.
