A couple.

First thing is to skip less marginal spots. That is for the simple reason that with faster rising blinds you are guaranteed less time to find good spots and run the risk of blinding down easily.

Secondly, I will often jam a bit wider, especially later positions like btn / bvb. Most hyper structures have bigger antes, and if the opponents are not factoring that in they will not call wide enough and that gives us a bigger edge.

Example

Here is a normal 10BB bvb spot with standard antes 1/3 (33%) SB

We jam 72% and they are supposed to call 54%

22+,A2+,K2+,Q2s+,Q4o+,J4s+,J7o+,T6s+,T8o+,97s+,87s

Now here is the with 1/2 (50%) SB antes

As you can see if they only call 54%, we can jam 88% now, and when you factor in that most players already do not call as wide as they are meant to—even with standard antes—it just makes for a nice edge!

Not really because accumulating a bunch of chips early doesn't have that much of an advantage in a hyper. I think the reverse is true that you rather play solid early so you can get the later push fold stages and take advantage of the pre-flop mistakes. In something like a PSKO hyper, then I think there would be merits to playing loose and agro early, that way you are getting bounties and covering more players later when the blinds go up.

That could easily be a spot where he has AA only, if that's the case I shouldn't even defend at all. I just was unsure and thought since I would call the jam anyways, just to put the money in. In hindsight, since the edge is small anyways I could have just folded pre.
