Curious about choosing very small sizing when we bet OTF.
Wouldn't be normal to have a large polarized bet?

A few reasons I would use a stronger range with a small size here;

• It is much harder to pile money in against 2 players. You want to force the first player into an uncomfortable spot as to calling or raising. He should be playing aggressively vs small bets but he will have 2 players left to act if he does. Betting large let's player 1 off the hook for having to play back as aggressively.

• They will have a somewhat combined defense frequency (with more of the defense lying on the last person to act) so it will be much easier for them to meet minimum defense.

• You want to force them to defend wider so OTR you aren't playing against the absolute nuts every single time.

• Both players have nutted hands in their range. If you bet big they can punish your ranges EV by raising.

• Players are likely fish and will under-defend by both calling and not raising enough if you use small bets.

• It is easy to get blown off your equity against 2 players so choosing hands that can play 3 streets is going to be harder.

There are so many reasons small bets play better in scenarios such as this. I am sure other people can contribute here.

As always, thank you David for all your high quality explanations!
However OTF I've made a mistake by betting big and SB x/raised me pretty small, so maybe I should have given up at this point. What do you think?

You are forced to call the flop. Then after he checks turn I believe the best option is 33%ish bet but that is debatable.

David Alford I thought the 33% pot bet on the turn is more of a thing when villains give ups are mostly back doors and gut shots that didn't improve, but here villain should mostly give up with weak FDs and OESDs and mix in some other stuff..

Thoughts?

Kalupso Generally I have found that it is very difficult to split ranges when OOP on a double-suited run-out. Seems that the solvers love to check here quite frequently (likely a board coverage thing since there are so many types of run-outs). That being said, I think most players do some sort of splitting where they polarize and check weak give-ups. My thoughts are that OOPs range is going to be extremely weak after giving up and that the small size forces him into an uncomfortable spot in defending at the correct frequency. As for a solver play - you may be right but I would have to run a sim to verify as I really do not know this spot well.
