I am fairly new to serious thought about NLHE, and am reading a lot about the kind of games that are seen in most legal casinos.

However I live near a casino which seems to have unusually loose games.

For example preflop raises of 6x-8x often get at least two callers.

  And if you bird dog well enough you can usually find a table where there is a player seeing more than 75% of the flops (often for a raise, and then usually seeing the turn as well).

It seems to me that almost any bluffing does not work in this game with the chronic flop and turner, and that even if I raise only with Ace Jack or higher, as well as pair of sevens or better, than I am often left with a poor hand by the turn.

What am I not understanding?

What is the optimum strategy against someone who is almost always continuing to the turn with any two cards?

What is the optimum strategy when this person  almost never raises?  What is the optimum strategy when this person raises about half the time (whether they have a decent hand or not)?

What is the optimum strategy against a table with multiple opponents who call your preflop raises (usually two,  sometimes three, and once in a while four)?
