Awesome video, great idea for a series!
One advice Andrew, send your participants the slides with questions a second before you start recording the video. Then you wouldn’t be forced to go back to reread the questions, because the participants could read them on their own screen. I think this would make it easier for them to concentrate. It’s pretty hard to remember the given situation while going through the possible answers, when you have to explain your thought process live while not being able to see the question and answers at the same time.
I don’t know if answer C has to be correct. This relies on how tight villains calling range is in the BB. I see quite some regulars, who only call with a very strong range in the BB, when somebody raises 3bb on the BTN. About 10% at best (and 3bet about 15%). This could very well mean these guys flat stronger broadways like AQ, KQ, KJ, AJ, some PPs and some SCs (And I have seen quite some players playing it exactly this way). So seeing him holding K10 in a 3bet pot doesn’t tell us that much, I think. I would agree with your conclusion, when for example we have seen AJ/KQ and A10/K10, because then we can be pretty sure villain can’t have very strong hands in a single raised pot, when the flop brings one or two face cards. On top of that I think it’s a much safer guess to conclude that someone, who is 3betting KQ and AJ 3bets K10, than to deduce, someone, who 3bets K10 also 3bets better broadways. Be that as it may, the concept of how villiains 3betting range affects his calling range in the blinds is very often overlooked and I like your thought process and the idea behind it.
Obviously all these situations imply that hero is some kind of regular, who is playing at least reasonable vs. 3bets oop, meaning he is not calling 3bets oop very often at all.
I also think SCS did a pretty good job in giving his thought process considering it probably was his first time to star in a poker quiz in front of a broad audience.
