PLO50 7643ss in 3bp 3way hitting nuts ott

the T♥: OTR counterfeits your nut straight, so now it depends on how BB plays the nuts when he gets 'em.
For me, I'll check back. The more aggressive players will bet/fold.

As always, what worse will call? Certainly no better would fold.

do we expect a tight 3betting range to cbet this flop? no? why no small donk flop instead of check?

for the river: you need to vbet if you see villain calling worse. youmention BBis taggish. BB overcalls preflop, imo thats some doublesuited/doublepaired stuff most of the times. I see he could bluffcatch good sets with straightblockers and/or unblocking FDs but we unblock those by ourself and its more likely he was drawing OTT.

another factor: If you bet big you wont get called often by worse. if you bet small you might give away you dont hold the nuts and might induce thinking TAGs checkraising you instead.

Had no look at spoiler but I think I tend to just check vs player that knows how to play the game

river feels a bit meaningless imo. shouldnt much happen as played anyway.
could try valuebet something around 10% to get out some bbs at least

preflop even on tight table clear fold to me as almost the whole table is quite deep. 7643ss is still close open at plo500 at the btn ip with 0,01bb ev
to the 3bet fold as well being sandwiched.

flop would bet as dont expect get too light bets 3way.
turn would pot as people tend be to stationy with their draws.

@BradNitt I would be very surprised if fold to 3bet+overcall preflop has more EV than a call.

tough to find it out exactly as i cant look at 0% combos on earlier streets in 3bet pots.
7653 would be okish f.e. ,but there the connectivity is better and it doesnt has the -ev disadvantage from the original open (think even when the table is quite tight. when all are deep should change it a bit and give more incentive to diverge from their default 100bb strat) so i would assume that it is more in the borderline region.
didnt mean the call is super bad, but i still would prefer to fold here with the lack of connectivity and therefore good flopability being deep in sandwich

Yes I also thought nothing worse would call..

I prefer to donk-bet the nutstraight when I have a bdfd. I am also leading this flop with nutstraight but not 100% so I am mixing it up here. But in general I am supposed to do more checking since I am not last to act.

I think the hand performs well against 3bets because of implieds even more since most regulars 3bets are barely balanced which means they play way too much high cards compared to low stuff and also overplaying their high pairs. Many nits 3bet sth lik 5% and with way too many broadways in it. I kinda prefer it over hands like QJT7ss or KKT9ds which would be calls according to solver but barely bring good playablity against continues postflop against tight 3bets to the table. I had so many stack-offs on dry K-flops with AAxx against top-set that I need to adapt against that ridiculously tight environment.

I would not open this hand preflop, sou I would have more problems postflop with low straight. You canot bet or call this on the river.
