KOTZ #12 PLHE Hand 1 of 2 -- Please help

[AceKQJT]

2nd Hand in the KotZ PLHE Event #12. I am assuming that all players are reasonable, as they are all 2+2ers (only 2nd hand of tourney, right?)

Preflop: AceKQJT (T-1500) is MP1 with J[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/diamond.gif[/img]. SB posts a blind of T-10.
UTG <font color="purple">(nottom, T-1500)</font> calls T-20, <font color="CC3333">AceKQJT raises to T-80</font>, MP2 folds, CO folds, Button <font color="purple">(lostchangi, T-1430)</font> calls T-80, SB (poster) folds, BB folds, UTG <font color="purple">(nottom)</font> calls T-60.

Flop: K[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/diamond.gif[/img] <font color="blue">(T-270, 3 players)</font>
nottom checks, <font color="CC3333">AceKQJT bets T-200</font>, lostchangi folds, <font color="CC3333">nottom raises to T-870</font>

I'll give the action and reasons later. Please give some reasonable advice here.
