Hey WV. You bring up a couple good points.
Firstly, in the video, I seem to totally miss the showdown of their hands which is just an absolute tragedy. I do see the sb had a weak hand there; however, I doubt that's from any adjustment. The maniac hadn't really shown his colors to that point. I do see the sb's stat's there he has a pretty high 3bet% in the small blind. So, maybe he's just doing his thing there (and it's probably a great idea), and happened to get in a hand with that dude.
There was some discussion in the DTB forums on the AKs hand. I think that hand can be played reasonably in several different ways. Some argued for just shoving preflop, which I think is probably just fine. The one thing that made me pause there was this player's open first in MP was only 5%. I think at the time i had 97 hands on him, so it's tough to say if that's just card dead or what. Given the J5s 3bet, I think a shove is probably a good play. As I said, I missed that earlier. It was that 5% and his tight stats that made me not want to get it in with him.
After my smaller 4bet and the maniac's call, you're right with the weird SPR. Looking back at it, I think I would prefer a crai really. He probably isn't giving himself any free cards anyway.
I think there's too much value getting more money in the middle to just flat there preflop really.
So, looking back at it, I'd just prefer to shove pre and probably have that maniac call with a really wide range and have the MP player fold the majority of the time anyway. And again, on the flop, I'd prefer crai instead of my push.
