Tough spots for sure. Any reads? I think a cll off comes down to that. I'll say this - I don't see him having AK (but 89 is possible) so if villain holding the stone nuts is unlikely I tend to lean towards calling in these spots. He could have 89 thinking that you dont have the nuts yourself because you only called ott. But that's why I say reads are important.
Also - - - I think tht I might fold turn with only 4 outs assuming a jam by villain otr is highly likely.
Good river fold. Villains likely hands for c/r flop, betting turn, and over shoving river are incredibly strong (98/TT/77). There are no value hands we beat. Opponent would give up on turn, or river, or bet smaller with bluffs. This line is looking to maximize value with a monster hand, and is figuring we have a good hand after raising pre, bet/calling flop, and calling turn.
