I agree with the post for the most part, However i also feel it is very important to be able to adjust your style to the type of players, Even though maniacs to your left is not where you want them. You have two choices at this point and that is one leave or two play tight. I think the second choice will hurt you in the long run becouse it makes you very predictable. Not to mention you can't play looser against the tighter table with out getting cought up in a hand with the maniac. now if the maniac is on your right it would change everything and allow you to adjust your stlye to the maniac and still steal agains the tighter players.
