11 remaining, first prize is around $90k, current payout about $6k. My table is 5 handed and I'm 3/5 in chips here. Other table has 2-3 shorter stacks than me.

Level- 10k ante- 30-60k

Villain UTG ~ 2.5m opens to 160k
Folds to Hero in BB and I 3bet to 360k with JJ. Stack ~1.8m total
Villain flats.
Flop 653r
Hero leads 300k.
Villain jams.
Hero?

First off I realize my 3bet was too small. Probably want to go at least 450k being that his open was over 2.5x. Any thoughts there?

Now after he jams is this a call? Villain is one of the best regs around with multiple titles and huge scores at this venue. His hand looks so much like KK-AA that smoothed preflop IP. I still have ~20bbs behind. 11th-10th get the same payout with a jump at 9th.

Thanks for the input.
