My read of the post is that OP was asking "What do I do if he's FSDRing?" I read it this way because he basically asks that question: "What is the exploit for a player who occasionally FSDRs, other than to continue to try to play my best and let them value-own themselves from time to time?"

And this returns to the question of how he responds to a 3-bet when he's raising for "thin value." Are we putting pressure on mediocre hands to fold? And how much equity is he folding when he folds?

I will say that from my perspective, the tipping point was that villain's two pair/trips outs are all in play. Often, when you have an overpair to the paired board, the opponent's two pair outs are no good against you. But the ace is an overcard to your overpair, and so those outs are still live. This makes his equity significantly larger (basically double) and making him fold right away has an increased value. (The preflop 3-bet matters here, too.) This makes 3-betting in this spot much more correct if you think villain is FSRDing.

I remain somewhat insistent, however, that 3-betting this as a *general* approach is a bad idea with your weaker showdown hands. You have relatively little to gain and a lot to lose, and this makes the risk/reward ratio on stepping out much more difficult on you. Being out of position sucks sometimes because you can't do as much as you can do in position. C'est la vie.

You should be wary of expanding that 3-betting range too far because of that. The last thing you want to do in a spot like this (imo) is to have the tables turned on you where you're now the one raising a mediocre hand and facing a raise (or cap) and now you've got an ugly decision to make.

For me (and I've said this many times ITT), I'm getting to showdown with this hand, but I don't want too many extra bets going in. If you're 3-betting, you should do so with the intent of showing this down even if things go sideways on you and he caps/bets the river. If you can't stomach that, don't 3-bet.

Such a move reminds me of the 3-bet/fold discussion with a straight from this post: https://forumserver.twoplustwo.com/1...aight-1684354/

Captain R's latest post is awesome, an example of the best this forum has to offer.

I also want to point out that Alan is generally aware of the importance of posting results, which is why his post is entitled "FSDR???" and not "FSDR!!!"

I agree, and I'm also a nit.

FSDR? What's FSDR?

"Free Showdown Raise," i.e. raising on the turn in the hopes that the river will check through.

It was fashionable among players ten years or so ago, but as a tactic it doesn't stand up to scrutiny through the lens of game theory.
