PLO10 ZOOM 7643ss

Ok so I don't know what his positional stats are for UTG raises but probably has a lot of A*** including AA** hands in it. I think your call preflop is marginal, it is ssso not sson suited wise (your holding one of your own outs to a very low flushdraw already). Probably not too many low cards in his range, so on this flop when you check raise him and he calls, I would personally on the flop already consider his calling range to have a lot of (overpair+) nutflushdraws in there. Most people with just a single overpair (no draw) will fold to this raise in my experience. Also I don't see a lot of made hands in his range like sets or straightdraws that got there on the flushing turn that he would then bet 7/9th potsizebet. Things cannot get a lot better for you, there is a lot of money behind and you have no real idea where you stand and no river card can really turn things around for you. I am a bit of tightish player so maybe others disagree, but I would probably let it go here vs UTG open-range that calls a check raise and then bets big on this flushing turn. It seems to me he is not fearing any check-raise from you at all, I think he his betting for value/protection (bit large though if he had the nuts here) but perhaps he puts you (amongst others) on a set and thinks you will still try and fill up on the river and will consequently still call a big bet. Just my thoughts. GL

Must defend preflop.

Postflop this is flop that hits you the most, so I would donk a lot of hands. Opponents shouldnt bet this flop frequently, or they must fold to check-raise. I also dont agree that there is a lot bad cards for you either when you have 76 too, only flush cards are bad. Could just call too, if you check-raise pot their continuing range should be very strong and you're deep, OOP.

You announced you've straight otf, so on this turn there is nothing to do but fold. He most likely has Ac flush, what kind of bluff could he even have? Maybe Ac3x (that could easily checkback) , or some double paired hand with 22,44,55. Still his range is so heavily AcXc that you must fold.

At micros I would raise flop, often getting fancy oop just means missing value. It's hard to get 3 streets of value from other than A3, but sets and fd will call you often twice. He cbets that board, so Acc is the most probable hand for him there. Easy fold on the turn.

Thanks.
