well, you three bet. Nobodys putting you on 34 offsuit here, everybody’s thinking aces kings, AK, etc.....
Then the board dumps two kings, what do you think people think you have?
I think you lost your value - or got all you were going to get - when you 3bet. Plus now you’ve set up a scenario where you donk off a lot of chips on a nice drawing hand if you did miss the flop.
People were already raising for you, you just killed the golden goose is all.
True, in this example I probably should just flat.
Same thing happens though when only a few people limp, at which point I'm torn between low key limping and hoping the board falls decently or getting some value in the pot and getting an idea of what everyone is holding.
