I think that note is really important. Probably the main use that I have for it is avoiding river c/rs for value, since if he's checking back some ridiculously strong hands I obv can't do that much.
It does also polarize river ranges a lot, which is great to know when I have a bluff catcher (and makes bluff catcher a much broader category, too). So in general I'm going to end up calling river bets a lot lighter vs. someone with that note.
When it's as extreme as that hand I noted (checking back JJ on a J65cccQ3 board with no indication that villain had a flush), it also just suggests that the guy's probably not thinking and maybe playing scared. So that's obv good to know in general.
I had two TT hands at the same time, so I guess I'll just explain both.
Top left: Preflop is fairly close, and whatever. I think 3-bet is probably best, but no big deal either way. I try to see more flops when making a vid, which is prob why I called.
On the flop, I checked my notes and saw that he raised pre and gave up a few times. People tend to be really really consistent with what they choose not to c-bet, so I think he has air a lot, so I might as well check and hope to induce a bluff on the turn. Once he doesn't bet the turn, I think it's really unlikely that he'll bet the river with air and if he has air, it's very unlikely that he improves enough for me to get any money on the river, so I might as well bet and hope he checked twice with TJ/QJ/Ax (which wouldn't be ridiculous at all, but pretty unlikely given my note).
Preflop's pretty standard. 4-betting is sorta an option, but TT doesn't really play well vs. his shipping range anyway unless he's shipping stuff like A9/99 which would be impressive even for him (if he ships like KQ/AJ that's not really very helpful).
On the flop I think calling is the only option. If I raise, I get it in vs. some worse hands, but I'm still way behind his range, and villain has been so aggro that I wouldn't be surprised if he barreled air even on a board like this.
On the turn, I'm not folding because I just have way too much equity against his range. If I just call, I think that given stack sizes I almost never induce a bet from worse on a blank river (he won't expect to have fold equity with air, and he won't value bet worse). So by calling, all I do is give him a freeroll with his worse hands, so I ship.
