Calling - a powerful play

I'm gonna put this one on here, half because it was a play I pulled, and fortunately, it worked out, and half because I need a little confidence boost after writing my last blog (The one under this). The game is $2-$5 No Limit. It's folded to the button who calls, the small blind calls, and Myself in the big blind with AQ suited. I raise it $15 more, the button calls, the small re-raises now, making it $20 more. (I like to steal out of the big blind after I sense the other players are weak, so I can just take the pot there), so I call, putting the small blind on a pocket pair under my AQ, and the button on just about anything (he's pretty loose). The flop comes down, 9 high rainbow. The small blind checks now.. I'm confused, I check, and the button checks, the turn comes down another rag, but making a two flush. Now the small blind bets out, I think, and call trying to make a pair or pull a move on the river if a scare card comes (straight/flush). So I had about 20 cards to fall that I thought would be good enough for me to take the pot. I also want to see what the button does before I commit more chips, the button called. He worried me some, but I thought I could take him off the pot regardless, he probably had the turn card, which was under a 9. He could have a draw, but I wasn't feeling it. (Too bad all the feelings I had in this hand were all wrong) So on the river, it makes a three flush (runner, runner). The small blind now checks to me, giving me the green light, I bet $100, a little less than the pot, even though the button could easily have had a flush draw (this is the only way I can win the pot, and its pretty decent sized). The button folds, and the small blind thinks for a while before folding kings face up. I felt bad because he was my friend, but I honestly didn't think he was that strong. I thought he was on low pockets or AK, AQ, making a play for the pot on the turn, after everyone checked the flop. Oops, I was wrong, and got lucky a scare card came to give me the pot. Nice bluff, I outplayed him here, but in a later pot he got me for more, with me holding kings, and I didn't let go, so I don't feel bad anymore. Hehe.
