Live Tourney Final table

[yellowfish]

This hand is annoying me for a while, still not sure if I done the right thing.

Live $1500 buy in, 120 runners, 6 remain. Blinds 5k/10k, ave stack is 200k.

I'm cl with 480k, villian has about 240k and is second.
I think I played the flop badly but thats not the point now. Anyway on a flop of KQ4r villian bets 24k fron the sb into a 50k pot I make it 75k from the co with JT, everyone folds and he pushes. Is it gambol time?

I'll be second in chips if i lose and pratically guarnteed top 2 place if I win. Payouts go from $8500 to $58000.
