Sit & Go Hand

Hey everyone,

I am still a learning player. Taking some of your advice from a while ago, I have been doing $1 sit and go's. I am still not doing as well as I want to, but I think I have been playing better lately. In any case, I wanted to ask your opinions on two hands. Since the hand history from BetOnUSA is for some odd reason not allowing me to paste into this box, I will describe the hands:

Hand #1:

Situation:
Blinds 10/20. 5th hand of sit & go, so I have little information on anyone. (Two hands prior, I had 3c-4s on the BB, check, flop 6c-5d-Ad. Checks around, 7h, and I win a 210 pot, so I start this hand with 1210.)

I am on the button with Jd-Qs and call because there have already been two callers, and I'm basically calling figuring to toss if I don't hit a flop, since I figure SB will call and BB check, since the table had been passive so far. SB calls for 10, BB checks, so pot 100, 5 players.

Flop: 8s-A-s-6s - Everyone checks.
Turn: 10s
SB bets 120, everyone folds, I call. (This is probably mistake #1, since he was betting approximately the pot. At this point, I thought he might have any flush, though).

River:3c
SB goes all in for 980. The pot is now 1320. Since the As is on the board, I know that only a Ks could beat me. I call, having seen people go all in with any flush in these sit and goes.

In reviewing the hand, I can see that the call on the turn was pretty marginal, and should have indicated that the SB had a strong hand. That, in combination with the all-in, probably should have told me something.

In person, I probably would have never called in this situation, but I've seen lunatics do this before online and I figured I'd double up if I won. What do you think?

Hand 2 (Different Sit & Go)

Situation: I doubled up on the 2nd hand (AA v. TT - he even put me all in after my 3xBB raise), going to about 2100. I won a few small pots, but began to bleed, and was down to 1560 by this point. 5 players left, blinds 80/160. I am in the SB with Qd6h

Everyone folds, I call $80, the BB goes all in for $490. I fold.

Should I have folded here? At this point, the BB was pretty desperate, so he might have been playing anything. Still, with the BB going all in and my decent size stack (I wasn't 5th of 5 in chips at this point, but ended up finishing 5th after bleeding chips away later on.), I was afraid to make this call with a Q high hand and a bad kicker. I think I made the right move.

Earlier in the sit and go, the BB had made relatively solid moves, and I hadn't observed anything really crazy, but he was about average looseness, for an online lower limit player.

Hand 2 is a good fold, best case you're a coinflip but you're easily dominated here and have no pot odds.

Hand 1... tougher. Maybe re raise on the turn and plan on folding to a re raise and then play the river cheap. At higher levels I'd say for sure you are beat if someone calls a re raise on the turn, but in a 1 dollar tourney... anything is possible.
