you have to remember when you get to the turn that by the turn our opponents range is not much weaker than ours, we get to the turn with 100% of our UTG opening range (lets say 18% of hands for e.g) where he has to go through 2 filters to reach the turn, call an UTG open from the BB, and chk/call AQ3dd.
With this in mind we should be a little cautious about what and why we bet - a hand like 4578dd I think makes an excellent candidate to check back, I think given we block nothing on the flop, no pairs/draws just two small diamonds then I'd say we have very little fold equity on the turn, and whereas we could certainly consider betting all three with this hand I think this would prolly be a mistake. I would check this back, realise my equity and surrender my 8 high if unimproved - we will want to check back a fair few hands with SD value here given how our oppo's range is now quite strong so we're protected against just surrendering the hand when we dont Cbet the turn.
The ideal hands imo to continue barrelling as a bluff here would be any hand involving a QUEEN, blocking AQ and QQ is very important as these are the two most likely hands to get called down by, if you were to somehow have the
in your hand too I think that would make for an even more appealing bluff as it further defines his range to a A*** one pair, or bad two pair hand which will really struggle to further heat. Obv this makes KQJTdd the most ideal hand to bet possible, as we have tons of equity irrespective and can even stand a check raise should that somehow happen.
