ok villain was just strange, made a lot of stupid stuff, seems like he is the kind of person that want to just "own" you, very unpredictable donk.

what to do on turn? i thought i have zero fold equity if i ship, also thought to get the rest of his stack if i hit, so call and get it in when improved? (expect to have 15 outs)

what do i do if i call turn and he checks to me on the river?

fold.

If you're not calling here it's better not defend this suited connectors card. I peel the Turn and reevaluate river. Also how much was the 3 Bet% and the 2B% of the villain? This is very important.
If you call and he checks river than you just check behind, you have showdown value with your 7.

I don't actually mind a shove if you think he might be semibluffing/bluffing here. Or maybe bet/folding, but it doesn't seem likely since he bet so big.

You have a lot of outs, but I'm not sure about the call. Also notice that all off your outs are not clean, since he may have two pair or better already. I think the call is meh, but I'm not against it, since you should have good equity against his range.

He has about 50$ behind and you have to call 44$ to 94$, so you're getting
44$ to 144$ if you think you'll get his stack on the river. That's 1: 3.27 if my math is correct.

You have 14 outs (9+5), so you need 1:2.29 to hit and you are getting clearly the odds for this. I'd still assume you have on average only 12 outs, which is 1: 2.83, so it's more marginal.

My math might be wrong, so feel free to correct me.

the huge turn bet with these stacks usually represents a draw that wants to price himself in to call a shove.

I'm probably shoving this turn and getting called by any FD or AK/KT/9T etc.

I just don't think you see a big hand that often when he bets half his stack on the turn.
