120 entry $550 200 bounty MTT

Beginning mid stage: blinds 300/600

UTG: 55k, Old man coffee type,
Small blind 25k: loose passive fish Hero is button, played fairly snug up to this point, 38K Utg 1/Hijack: unknowns, about 25-30K stacks

Preflop: Hero dealt AJo

UTG limp, Utg 1 limp, hijack limps. Hero calls 600. Small blind call BB check

Flop: K Q T rainbow. Blinds check, UTG bet 600, folds to me, I raise to 2100. Small blind calls, UTG calls.

Turn: 8, full rainbow now. SB and UTG check, hero bets 7300, small blind and UTG both agonize, and eventually fold. UTG showed before muck.

Did I miss a golden opportunity? Should I be raising pre? Or be worried about the classic OmC limp/reraise.

Should I just flat flop? Even though it was such a small bet? What hands should I raise on the flop if any?

As played should i bet more/less or check turn?

I can say what UTG mucked but i think its best to leave it out for now.
