Villian is a pretty tight tag. I haven't seen him get out of line at all. Preflop my standard play of course is to 3-bet but sometimes I like to call TAG raises in position with AK, just to disguise my hand a bit. On the turn, the best case scenario is that we are splitting. But a lot of times, I think that this overbet means that he's freerolling me. How deep do we have to be for me to consider folding this (I have a feeling it's something around twice as deep as we are now but I'm not really sure).
