really enjoyed the video talking about timing tells. I was also studying that this week. :D
Would love to see a part2 video.

22:55 T#2 It appears 88 is mixing the turn, betting about 40% of the time with and without a heart for a small 20% sizing. You did say you are on the fence, but I don't think the pool is XR bluffing enough with hands like AxQh to punish you for block betting. Also solver doesn't appear to be check raising AK / AQ with a heart. It will with AJ with a heart though. When you bet 20% pot opponent will be getting 6:1 so direct odds, which is why I am guessing these hands don't check raise? Maybe if you bet 33% you can slightly deny more of their equity.

31:30 KQd and most of your range prefers a larger bet. I put range as "full height" so it's easier to see because a lot of your range is betting earlier streets. I think one of my leaks is falling into this trap of trying to look "value heavy" with my bet size when I'm actually bluffing. I think we just end up leveling ourselves thinking the other player will fold, but 75% to all in size is preferred.

Cool format, analyzing hand(give ranges and common holdings for villian) and afterwards see showdown and get feedback on your thought process and assumptions.

It looks like you have a great view out of those windows

Overall I like the video and the timing analysis. I too have noticed that tank 4 bets tend to lean heavily toward the stronger part of the range and snap 4 bets (and especially snap 4 bet jams) are very frequently AK.

That hand at 4:10 where the player led out on the Q1010 board--
This is somewhat common from weaker players at lower stakes on Ignition (which I think shares the same pool) and it is very frequently top pair in these multiway pots and almost never a nutted hand like a set or in this case a 10. When called these players will usually continue betting small on further streets and when raised they frequently give up if they have a weak kicker.
