UTG ($1800) Tight-aggressive reg opens to 25. Hero with $1000(splashy LAG image) flats TT from HJ. BTN (reg) with $500 (has been 3betting hero frequently and is aware of Hero's image. My read on him is that he cbets a little too frequently and is relatively tight-passive post flop) 3bets to 90. UTG calls. I elect to call.
My read preflop was that UTG's range is capped. (Flatting QQ+ or AK at this depth would definitely not be the standard play and require more thought than the way UTG chose to call in this hand). BTN seems to have an auto-squeeze hand as it didn't take much time for him to 3bet either. What do you guys think about back-raise jamming here? I think UTG is dead money almost always (except JJ maybe?) and BTN might have some 3bet folds in his range. I can't say at what frequency but I can also be sure that I will have some KK AA combo at this spot, AQs is another hand I would consider doing this with.

The rest of the hand went quite uneventful, we flop gin on T89r. Checks to BTN who shoves for 280. UTG folds, we call and scoop. My other question is that on the exact same spot, if we are the BTN in this hand and assume we 3bet preflop with a reasonable and relatively linear range. Is this a board we should be checking at a high frequency? Thoughts about c-betting flop 25-33% with most of our range?
