I think the HU example is a very different case. We are playing versus one player in position, and I guess you mean bet sizes greater than pot, so NLHE? I mean in PLO you can open in GTO 100% at any openingsize I suspect.

The effects of betting smaller in the video-spot means your fold equity is a lot lower. The IP players can flat you a lot more and especially if you widen your range the IP players should 3bet you more frequent which is very bad for your weak hands. On the other hand the blinds might 3bet less since the stackdepths are a lot bigger which seems to me a big plus. But the blinds will defend more versus you which again should be bad for this hand. A upside to this is the cheaper cost of opening.

I would personally think that the minusses would outweigh the positives for weak hands and that you therefore should open less. Interested to hear your opinion on this.

At ~13:30 Hero opens A345ss and you say you think it is too loose, but "he is minraising so he gets to open a little bit wider". I don't really understand this, minraising gives better odds for flatting, doesn't a minraise make you open a little tighter?
