Stealing frenzy, how loose can you go?

[stokken]

Late stages 10 left outta 800+, stars 11 rebuy. blinds 15K/30K ante, table is a mix of a few experienced tourney players with a large number of Ft and money finsihes, one appears as thight relative to the circumstances. 2 of the players are though and raises every time they have first in vigourish. We are 5 handed.
The frequency of the raises suggest highly that any two are about good enough for these players.

Lp raises to 90K( one of the 2 mentioned players), sb rather thight

Chipcounts lp 700K, SB 400K, I 400K

My hand is TT. SB pushes as response to lp`s raise. I believe his range leans more towards AK-T or low PP, but cant be absolutely sure, because he would want me in I think if he held premium PP and just flatt call or up the stake just a little. I am positive that LP will fold a high number of times in response. Fold or call, if you win it the final table will start, and you enter it as chipleader. First prize $8K+ tenth pays $360
