Do you go allin here?

[joker1976]

party NL 50 SnG, level 5 (100/200)

6 players left, stack size 2400(UTG), 800, 1200, 1800, 2000(SB), 1600(BB, hero)

table is tight, UTG has been limping a lot, steal bet on flop with position, the rest of the table folds a lot.

hero dealt TT. UTG limp, SB, a tight player, raise to 700. If UTG is a tight player, SB will not raise in his position without a monster hand, but he might as well observed UTG's play pattern, try to isolate or steal from the table as UTG could have any junk like Q8s or 67s. The blind is already very big, successful steal can make huge difference in stack size.

what's your play here?

I went allin, and of course SB had AA.
