Queens in the small blind

[Shaun]

You are in the small blind and have everyone covered with 350 or so. The game is tight, 1-2 blind no limit. MP (120) raises to 5. Do you re-raise here?

Next: assume you just call. Then, the big blind, whom you haven't seen play too many hands, (150) makes it 20, and the original raiser folds. Call? fold? raise?

Finally, assume you just called again, the flop comes T, 8, 2 rainbow. Raiser bets the pot. Call? Fold? Raise?

Now, assume you had KK instead. How does your play change?
