regarding the T9o hand in the beginning: you say you have about 27 to 30% equity against a reasonable calling range. can you please specify his calling range?
Board: 8c 9d 5d
Dead:
equity win tie pots won pots tied
Hand 0: 26.412% 26.19% 00.22% 6741 57.50 { Th9c }
Hand 1: 73.588% 73.36% 00.22% 18884 57.50 { AcAd, KcKd, 99-88, 55, AdQd, AdJd, AdTd, A9s, Ad8d, KdQd, KdJd, KdTd, QdJd, QdTd, JdTd, 98s, 8d7d, 7c6c, 7d6d }
I did this quickly (so I may have made an error), and kind of worst case scenario. You can play with pokerstove and add/remove pieces and portions and like Krantz said in the vid, check out ranges of ranges and see how it changes
In this version I sprinkled in a combo each of AA and KK, which he may not have, and he may never have A9s, he may never have 67s. So keep in mind this is just one way to plug it.
