1- I disagree, folding is the best option even if we have no diamond, BB's river donk lead sizing does not generate enough fold equity so he is rarely bluffing and has so many Kx and Jx, plus hero is chopping with Axdd so hero's pot odds are not looking attractive vs this region of BB's range odds became 2.5:1 and not 4:1 anymore, so its a really bad call no matter how good your odds are, the ev of a play is not affected with pot odds as much as it is affected and even defined with the players ranges and the action. this is not a great call not even close to being a good call.
2- at 2:02 its not tight its passive, and we can justify the flat with the fact that we are protecting the weak region our flating range on the button it may affect our 3betting range thats why its not a 100% frequency play. On the river its a clear fold due to the fact that the co still has over pairs in his range he may be thinly value betting a strong 9 and if he is a good player he must have some Jx to protect his line and his turn checking range like JT QJ.. it has nothing to do with odds and blocking QT is almost irrelevant.
3- it's a really terrible cbet, and utg used 1/2 pot? oh god help me finish this. it's not standard. the BB has A LOT of 7x in his range so he needs bluffs to balance his XR range and so he must start check raising aggressively with 89cc for example and 56cc and diamond draws obviously, so hero must do a lot of checking on this texture pot control and protect his checking back range on this flop by checking back some Ax with one diamond like in this case we have Jd..... anyway Im tired of writing and this is frustrating, its okay that a lot of people think they're good but I dont like the fact that...forget about it. On the river hero is blocking a lot of the BB's bluffs with the J of diamonds so its a fold with some reasonable frequency, it was not a good call even if it were +ev it would be almost breaking even. Im tired no more analysis.
4- it was almost a 100% shove preflop and a 100% range cbet using 1/4 pot sizing euuuuhh this is just bad imo no offense.
play with reasonable BRM...lesson learned I will never break my rules again.
