K7o blind vs blind - bluff-raise river?

What flushdraw checks the flop though

Why do you assume he has to bet a lot out of position? He easily could have flushdraws in x/r and x/c ranges. GTOWizard is checking there ~70% range from SB.

Also you cap your range on turn and this raise is pure spew.

I perceive him pretty weak

Without information you dont want to perceive players like that. This will cost you money. You cant define what his check means. So check behind OTF.

OTR i will give up and fold. Making such a moves blindly is no good.

Interesting replies, thank you. I'm kind of struggling with blind vs blind play in general, it takes a lot of practice to master and I'm sure my game needs improvement. Lately I've been experimenting with a lot of different lines in these scenario's. In this hand I went completely off-board and villain snap-fold, but I wasn't sure if it was good. To learn the maximum from it I immediately posted my thought-proces to it. Apparently I don't know how to construct ranges good enough in these scenario's. How wide do we really want to defend post-flop on this board? What hands do we check-back?

After review I think we want to stab flop with hands that can pick up equity on turns, so we can 2nd barrel a decent amount of the time. Does anyone have some good learning material for blind vs blind play? Some books/video's?

Information and well sized opponent is the key. You can stab your entire range if you have decent FE. Your problem is that you construct ranges based on your hand strenght. The more you know about your opponent the less your hand matters

Well said.
To bluff successfully (meaning that opponent folds) your play must be consistent with your play on all other streets, and in this case, I think that checking back on the 3rd diamond breaks that story.
OTOH, bluffing successfully can also mean that opponents see you bluff in a particular spot, then are more willing to pay you off when you have the nutz. You can't do that here because it costs too much.

So this isn't a good spot.

You could turn K7o into a 3bet bluff preflop.
It seems really wild, but you're allowed to do that because from the BB you'll benefit from building a polarized 3betting range (as from the BTN, basically to balance the wider calling range from these positions).

As played, I don't mind the bet OTF, I think the sizing is ok. Ranges are ridiculously wide here, your equity is trash and it's unlikely to improve on later streets (except from the BdFD). Keep in mind that if villain check-raises you are out.
But, as everyone stated, once you took that decision, you should've kept betting OTT because your equity improved. I'd go for a large bet but I'm not sure about that.
OTR, having checked turn, I don't like the raise. It's not impossible to represent a slowplayed flush there, although risky, but you want to have at least the Ad and know for sure* that your opponent is capable of folding a weaker flush.

I honestly think there are better spots to bluff, tbh.
All villain needs to call is some decent blocker and something that beats air (J or Q). Since you don't have A♦ nor K♦ blockers, one of them can very well be in villains hand and if so, then he'll know you won't have the nuts (or at least 2nd nuts) and may re-apply pressure himself.
Hands like AQ, KQ, AJ, KJ, AT, KT with A♦ or K alone would be enough to make you sweat. Hands like QT, JT with T♦ can call your raise (with frequency, i think) and most likely, T9, 98(?) with a also (less frequency).
Probably, villain didn't hold any to block you, what makes his call very difficult, but that will ony happen 1/2 the time (1 suit, 2 cards, think the math is that).

Now, something I didn't get: If villain wouldn't check any FD on flop... would you check any flush on the turn? And also, any that you would check turn after betting flop and raise river with?
