I suck, but how badly? 2/4 B&M hand

[Slim Pickens]

2/4 at Gold Coast:
The table has been oddly weak-tight save for one hypermaniac (M) and my friend, who I now know is capable of check-raising and folding to a 3-bet, which should be disallowed at 2/4.

In the hand in question, I am in MP with A[img]/images/graemlins/diamond.gif[/img]2[img]/images/graemlins/diamond.gif[/img].

Preflop:
folded to me, I make a very loose call, three players limp behind me, and M on the BB checks.

1) I contend that aside from making the wrong choice at every other possible chance, my flop raise with an overcard plus nut flush draw was correct considering the table was, IMO, still loose enough to get two callers behind, and more likely 3 than 1, and possibly een a reraise from the maniac where I get to cap if enough people called my first raise such that I have an equity edge.

2) My preflop call was terrible and no one can debate this.

3) My turn check was _______.

4) Raising the river doesn't really work unless the maniac calls me without a straight and neither of the fish behind me has one either.

See, this is why I don't play ring games. I suck at them. Someone care to comment?
