I'm getting better than 5 to 1 on the turn. Considering that he may have the deuces underfull, or tens over twos, or AKJT, or just be looking for a cheap draw, then these things make the call much more palatable. As Pete said, if a LAG can get u out of a pot this easily then you are going to have trouble just playing the game. I agree that its probably -EV b ut when you throw in the other factors above, including that a case Ten could be a return of 18 to 1, then its not too bad.
