1. Is my preflop call ok or should I be folding my way in?

If you can fold into the seat, do it. Let someone else bust him. It would suck if the flop was AQ4 and the SB had something like 44 and UTG+1 had QQ. Now you're short-stacked and might not get the seat. Now SB goes all-in, you call, and you are terribly short-stacked. While this is an extreme example, it can happen, and you want to prevent it. Folding is the easiest way, especially since you're like 2nd in chips.

2. Assume the UTG allin and it folds to me, should I call?


[/ QUOTE ]
No. Again, let the other players bust each other. At this point, you could fold 90 hands before you bust. Someones going out before you.

3. While I can think of a few scenarios where SB might benefit from betting on the flop, it still seems highly unlikely to be a good thing for him. Is he insane to be betting here?

There's an all-in and a call already. IMO, he's insane to even be in the hand to begin with.
