Man, am I weak?

A great 20/40$ session last Saturday. The perfect mix, about four fishes, a couple of lose/passive player, my tight bro. Usually 4-5 people to the flop. The seldom situation occurs, that everyone folds to me and I find AA, so I raise. Both blinds call. SB is a lose player who is kind of tricky, and definitly bluffs too much. FLop comes down like this:

Don't like it too much, but however. SB bets right out. BB calls, and I raise.

Turn: 8 [img]/images/graemlins/diamond.gif[/img]

Wonderfull, it's checked to me. Damn, what shall I do. I guess I should bet again, but I am acting like a sissy and check.

Nice, now there's a staight. SB bets out, BB folds and I think for a second, counting the chips in the pot. Now there's 280$ in the pot, and the chances he's bluffing is definitly more than once out of seven. So, I call. He shows TT and we share the pot.

I don't like my play here at all. First, I think I should bet the turn again, despite of the chance of getting check-raised. Additionally I think a bluff-raise on the river would also have been a nice play, as I know, SB is such a frequent bluffer.

What do you guys think about my play?
