Bluffing against a fish

I think your read is correct unless he's the type of super face up fish that donks flop or turn with his Kx, is he that type? I expect his range is compromised of a mix of weak Kx, missed flush draws, and missed straight draws and you need to find a third barrel because your turn barrel was too small. Unfortunately you need to find a size that gets weak top pair to fold so have to go huge on this river (unless he's that face up as mentioned above). Time to grip it and rip it.

Btw I think if you had this spot but missed flush draw instead of missed straight draws you can give up. But you have so much added fold equity against missed flush draw too with this hand.

Grunch:

PRE - playing this deep against a loose passive rec who likes seeing flops, I might raise a tad bigger, like $30 or even $35, to dissuade loose calls from behind.

FLOP - seems fine.

TURN - would prefer an over-bet on this brick.

RIVER - still seems like we can fold out his weak Kx with a big bet. But we could also bet on the smaller side just to fold out his bricked draws and weaker pairs.

Yes, turn ideally would be a very large bet like 150 to jam river.

2 on the turn that doesn't bring in any straights is the classic blank turn where the nuts don't change, especially when it brings a second flush draw. I would probably always overbet this turn and consider jamming the river.

As played probably overbet river. Something like 400-500.

And if he stations you, then take note and wreck him with value next time.

But what if I don’t have enough stack depth to overbet the turn and river? For example, if my stack is $750, that means after a $200 overbet on the turn, the river pot would be $500, and I’d only have $500 left. In that case, it’s not enough to pressure weak kings to fold.

Usually in these games stacks are shallow and we don’t even have $750. With a $500 stack, the situation gets even trickier. Basically, I only have one big overbet left, and now I need to decide whether to make it on the turn or the river.

There is content for adjusting to deeper or shorter stack depths online. Marc Goone just posted this one, as an example:

In broad strokes, you could size down with your pre flop and flop bets, and / or look to play a two street game instead of a three street game, where you'd be shoving turn instead of river, or delaying our big bets until the river.

Also want to tighten up the pre flop ranges, shifting towards high cards and more PP's, with less emphasis on suitedness, and away from suited connectors and weak suited aces.

In theory, I'd expect that if you started with $750, V should be folding more turns, expecting a pot size river jam. But like Mlark said, if this guy doesn't fold enough, make a mental note of it, and the appropriate adjustments. Pull back from the edge before you jam river as a bluff, and shift your range more towards value.

Basically, the shorter the stacks, the more value oriented we want to be, and / or the more pressure we want to apply with a single big bet on turn or river, rather than spreading the pressure over both. I'd guess we'd want to be even more value oriented if our opponents are sticky.
