Concerning the preflop jams w/ AA at no-limit tables:
I've been doing some crude piece-wise integration of average flop equity calculations (Slowhabit demonstrates this in his "The PLO Handbook: Transitioning from NLHE to PLO") and in general, without a pocket pair or an A in your hand (assuming your opponent has most AAxx and not just strong AA), there are tons of hands you can call with preflop that are plus EV when you 3bet and face a 4bet... Probably most excellent (excellent being a relative term) PLO players know this intuitively or explicitly already. In some cases, it's not even thinly profitable, but very profitable. The key to the profitability seems to be centered around the player who faces a 4bet not having to call off more than 1/4th of his stack. I did some additional calculations and it seems that once you start having to call a little over 1/4th of the remaining money preflop, you start having problems breaking even with most everything but the premo-drawing hands.
Anyway, so I messed around for a bit w/ like, 3betting to 50bb w an AA hand as good or better than AA8Tss, and some really sloppy players will call with a wide range. But some of the more reasonable (like 40/20 or 30/15-ish) players will mostly fold it seems. However, they seem to all think that around 30-35bb's (100bb stacks) is more of a call. I'm getting called about 8 out of 10 times so far when I make it this size, even against sub-30VPIP players. The interesting thing is, I've only gotten action on flops twice so far, and once was from an 80+ VPIP player. This is, of course, really small sample size, but if you could get called preflop most of the time for 1/3rd of player stacks, and you have AA, you're forcing them to make a decent mistake with the hands they call with even if they commit correctly on appropriate flops. In addition, if they aren't calling the flop with any piece, they are making another pretty big mistake.
In the case that they are making mistakes postflop (such as folding T986 on a 63Qr flop to your flop pot-sized AI), then we can start doing this w/ non-AA hands. There's no way to get an idea of what's going on postflop without a 200+ sample size, but can you see where I'm going with this?
Of course, I am mostly playing 25PLO atm. Things could be different at 200. But for the most part, what I've seen from these videos is that, players that fit into a certain profile behave essentially the same. Rec players still have a really bad sense of pot-odds, at any point during the hand. And there are actually 200PLO players that are playing in the 25PLO games (eg. ef5tornado and smok3alot420, in this particular video). I even see two regs in this video down at 25PLO, so....
