Have you guys noticed people donk-bluffing a lot?

Typical scenario: dude playing 2/5 three seats to my left. Limps UTG, calls my raise from the button, and then donks out if anything remotely scary shows up on the flop. Folds to a re-raise. Does this over and over.

I found this really bizarre. Not sure I've seen anything like it. But now I see people doing this all the time. I mean, it's cool and all. Don't even have to bother looking at your hole cards. But if it's a trend, some adjustment is required, I think. If nothing else, we should be on the lookout for this sort of tomfoolery.

To be fair, in its own ******ed way, it's a semi-effective countermeasure against something we all have in our playbook; ie open-raise light in positoin, cbet, fold to aggression. Guess that's why they do it. Not what I would do. But it works, until it doesn't.

This is very common and I've been seeing this for years. It's usually a "feeler bet", meaning they have something really weak like bottom pair or middle pair, and they are trying to "see where they are at" by "betting for information". The premise is simple: If you raise, they know they're beat. Hence why bluff-raising them is so effective. I auto raise 100% of donkbets until they resist.

Now be careful if the board is multiway and particularly draw heavy and they donkbet LARGE. This is usually for value. I.E. the flop is 567hh, they probably have a set or flopped straight or something and are just to either get everyone to fold now, or at least build a big pot for someone who decides to call.
