I'd go ahead and call because the odds are great then I'd donk out again for like 20cents hoping they min raise again and I get this hand to a showdown and take note of what they do this with. Of I'd be donking bigger if we make our hand.

Pre is borderline. 98o is my cut off point unless BB is confirmed folding too much.

C bet looks fine.

Turn looks like a call for a min raise. It helps that we have showdown value now to compensate for a lack of implied odds for your straight draw.

Pre I think is probably just about OK, we can fold this type of hand for sure either though without any hands on villain. Normally I 3x SB vs BB though, 2.5x is offering very attractive odds for villain to call (correctly) with quite a wide range which is bad for us. By 3x'ing we are investing only .5BB's more but I do think we get quite a decent number of extra folds.

On the flop the C-bet is good with the open ender. I think when we pick up the 7 on the turn though we can go into check call mode. We have some showdown value if villain has some sort of float/draw type hand and I don't think we are folding out many better hands with the double barrel, maybe some 9x but that's not guaranteed. As played I call the turn min raise given the silly good price and donk out if we make our straight and check call if we hit trips. If we hit two pair then we have a tough decision if villain bets and it would depends on his sizing but I think more often that not we should be folding on an 8 river.

As played this is pretty easy odds call even if we account for the fact that you're OOP. I'd actually consider check/calling the turn vs. some players given the fact that 7s actually gives us some showdown value BvB.
