So let me get this straight, you have TPGK or an Overpair and You won with that at a 1/2nl game...

Wow, who would have ever thunk?

I'm always amazed at how fish and donks think they are so clever. If you are so clever why not do the same thing when you have mid pair or bottom pair or only a bluff catcher?

Seriously, if this was a "truly" winning strategic move you should ALWAYS do it when you are last to act on river. In fact, why stop there, do the same on the turn .

It's totally fine and part of the game. Doesn't mean it will always work tho. I had that exact situation last week, I was playing 2-4 and made it $40 with 88 from the SB (after 5 limpers) with $1200 behind. The BB flats it with $1450 behind. I've been playing with him for a couple hours, he's a donk who thinks he's good and that he has uber reading skills. Another couple of players also call. Flop comes QsTc8c and I make it $100. BB raises to $200, the other 2 fold and I shove. He shows me AA without the club and asks if I want him to call. I say it's his choice and look worried. He makes the call.

Not at all. This has always been a standard move in poker (despite some rooms' now sanitizing the game to prohibit it).

But it's not much of a play, usually.
The fact that it's worked for you really doesn't actually mean much. You got the stock answer (either silence, or "That's up to you"), and were lucky that they were bluffing all 3 times. You will usually get the same answer from players with the nuts. And against better players, you won't get much of a read on them from what they say, or how they say it (or stay silent).
So don't worry about the ethics here, but I would suggest you work on your hand-reading and analysis skills more.
And if you're going to do this, I'd leave out the part about promising to call.

OP gets same reaction with cards face-down, imo. I mean...if you want to do that whole "Whaddaya got?" routine, I guess that's okay...but you're not going to get any more reads with them seeing your cards than not.

This is not unethical. It is banned in some rooms and likely some home games. Check out the local rules. This is also not a good habit to get into, because it is hard to get serious info from the V unless he is a total beginner, a good player will not usually give you the feedback you need or will give you a false tell. This is also a good way to get a good player who is a bit if a dickhead to simply smile and call a clock on YOU! Lol

so what do you do if he says please call

do you follow up or fold?

I would act overly worried, scratch my neck, ummm, errr, wow, geez, look at your hand, check the board, scratch my head and say "Wow, no, I'd really like you to fold there!"

What do you do then?

Yeah, this was the first thing on my mind, and I don't understand why so many people are posting seemingly without talking about this part. Doesn't the angle/scumminess rely on this?

Since you're doing this for information I guess that must mean you will fold if they say "okay, call", which makes it pretty scummy imo. Certainly not a sporting move and won't make you friends at the table when you fold. You're taking advantage of a) that they might think what you said is binding, and b) that people naturally want to believe that someone isn't screwing with them when they firmly make what seems like a genuine promise, even in poker. Maybe to some people that's fair game and they will compare it to bluffing or some crap, but I don't think it's the same at all.

ive worked some angles with it and it seems people do the opposite of what you say

for example i have a draw and i go all in the person with top pair is debating calling or not

kept talking and tryna put me on a hand asking if i got trips or have them outkicked

i tell them i promise i dont have trips im only a draw please fold tryna inception them

but when it looks like there about to fold to try and get a reaction out of me they call

and i hit my straight serves em right

Its fine, I wouldnt bother with the "I promise" bit though.

It's fine, but some rooms would determine that your hand is dead when you flip over your cards. It seems like plays like this only hurt people long term from what I've experienced.

Some rooms may consider it binding if the person says yes. Be careful.

Not unethical, though I do try to avoid doing things that have a good chance of making me look foolish.

At the casino I play at live in the Midwest, if you reveal your hand- your hand is dead... So this strategy wouldn't work so well.
I agree if the poker room allows it, it's NOT unethical.. perfectly fine.

Is this bad mannered? I raise qq utg guy with 200bbs (i cover) calls flop q high i cbet he raises big i fake tank then ask him if he will show if i fold. He says he is honest man and will show nme if i fold then minraise him he ships i snap he gets rly angry at how i played it? Is that an angle?
