So, its 1R, AO Tournament, seven players get entry for Main event in local Casino promotion.
23/88 players remained after 5h of playing and blinds are 1200 2400, ante 300. I have cca 33K and hold 46s
(we started with 4K, AO was 8K).
3 players limped and I decided to call in BN having huge implied odds for 1 big blind.
SB folded and BB huge stack guy completed.

FLOP(15 300): 8dTd2h, BB checks, UTG+1 bets 5K, HJ folds, CO calls...

HJ has cca 24K, CO has cca 35K. I have 46 suited in diamonds and decided to push AI
Counting UTG+1 calls with hand like AT and CO folds hand like J9 or whatever....
BB is obv weak.

What would you do in my shoes OTF?

PS Preflop should have been fold?

Thanks
