In an attempt to both look at specific hands and also be able to generalize some concepts, I present the following:

Villain in this hand is an older guy who is a reg in this game because it gives him something to do while he's not risking hundreds (and maybe thousands?) at double-hand.

He's on the tight-ish side of the spectrum preflop meaning he'll play lots of suited garbage multiway, especially in position, but definitely will fold stuff like dominated aces and other offsuit broadways to aggression, so I guess he's got a clue. He also has a pretty good line on my play.

UTG limps, villain limps, I raise AdQd, I think button CC, BB, UTG and villain call

Flop 4d 3d 3h

Checks to me and I bet. UTG calls and villain CR.

I think I'll stop here with what I think villain's range is:

Call 3 times, raise if you improve. Im sure most people 3 bet the flop

Also in call down mode. This is a dream bluff catcher.

Just because he will check-raise a draw doesn't mean he will 3-barrel with it if he misses. Not that many players will try to pull that off.

So your strategy here is to fold 100 percent of rivers after you take the call flop/turn line since you bssicslly never have overpair.

Not like you can bluff catch 88 since that has to 3 bet the flop

Why does 88 have to 3 bet?

Never raising and never folding flop. Raising turn if I improve

My "standard" play here would usually be to call, call turn UI and evaluate on river misses, but I was thinking this guy could be not-strong-enough where raising might get him to shut down and perhaps fold a small pair on a later street if I miss. Alas...

UTG folds, villain calls.

Turn Js, villain bets

Just call here or continue with the story?

I think there are a few good reasosn, but presence of UTG player is probably the main one. I guess he folded but I assumed he is peeling for one more bet

I think OP 3-bet the flop and UTG folded for two.

Ah crap, yes, I went non-standard (for me) and 3-bet

If you mean that you'd raise actual improvement plus perceived improvement, that's fine.

But we've got 40ish combos of overpairs here, and something like 10ish flush draws. We're actually short bluffs, not values.

3-betting with the intention of barreling vs 1, checking vs 2 (and maybe even betting a turn K vs 2) isn't as bad as everyone makes it out to be.

The fear of them 4b our transparent free card play is overrated. It's 5-way on the flop so our cbets are highly value oriented, which is something villains will miss (like we're not cbetting AKo here but they will probably make a FTOP error by assuming we do). Our pairs crush their value range. People overwhelmingly delay 44 and 3x.

Bluffing with AQ here so we can fold out KdTd doesn't do much good. Unless you think people actually bet/fold 66 ever here

Unlikely 66 will fold the flop, but sometimes it will fold the turn or river. KdTd is never folding before the river no matter how many times we bet so that's a strawman.

In general I like the 3-bet on the flop, but it depends somewhat on the players involved, as does our turn decision if unimproved. There is almost no one against whom I like the plan to just call down all streets unimproved, keeping our hand just a bluff catcher, especially while the third player is in the pot.

I meant KdTd folds blank rivers, or basically we only bluff out bluffs

That's to bad, because I think it's usually correct to do so. I will say that it becomes more and more correct the bigger you are playing. I still think that the average 2+2 player type 3 bets here a ton and often to much, which is largely a product of them being terrified (or not knowing how) to play a hand without the initiative

Just seems to me you're not getting 4 bet often (especially at 6/12), you are often a 3-way money favorite on this flop, so it's not that bad even if you do get 4 bet, and if the 3rd guy folds leaving behind his dead money, that's not really too bad either.

Quick question: if you knew the CR had 55 would you prefer the 3rd player to fold or call?

I guess it depends on what he has. With most hands I would prefer him to call.

But if the CR has a draw himself, which both you and OP seem to think is likely,
I would greatly prefer the 3rd player to fold. That parlay may be difficult to hit, but it would be a huge coup if it did.

So we should 3 bet the flop in case the guy that CR has a draw and the 3rd player turns what likely a 4-5 outer and then he also fades our 15 outer?

No, in case the 3rd player folds the best hand. Like if he is the one with the 55, and the CRer has the draw. I think a lot of players would fold that for 2 bets cold.

But again, I'm not saying that situation is likely, just a possibility, If he calls with his weak pair, we're still likely a money favorite in the 3 way pot. If neither player has more than one pair, aren't we almost always going to be a favorite here?

That was exactly the read given, but chillrob's description is pretty correct - they will c/r/c flop and c/f turn with 66, especially if an A or K hits the turn but maybe Q or J as well.

That's the read as OP but everyone is translating that to bet-folds flipped over pairs on turn

I didn't see anyone suggesting a semi-bluff turn raise.

I did.

ETA sort of. 3bet flop, bet any improvement plus turn K.
