Percentage Standard Open Ranges Hit Rainbow Flop Textures
I have just completed a long project of creating matrices of the percentage amount standard open ranges from each full ring position hits every possible rainbow flop. Although most of the value is probably from doing the work myself, I will attach the final product here, if anyone is interested. I am clear about my assumptions regarding what a "standard" opening range is and what constitutes "hitting the flop," both spelled out in the preamble. I am also realistic about the possibility of errors in my calculations. But, I think it is okay for drawing general conclusions. I paste a sample of one of the matrices below so you can see what I am talking about. The alignment on the actual matrices is not reflected below.
Jack High Boards
UG 9% 120 Combos AA-77, AKs-ATs, KQs-KTs, QJs-QTs, JTs, T9s, 98s, AKo-AQo
J 9 8 7 6 5 4 3 2
T 100% 100% 100% 100% 100% 100% 100% 100%
9 x 65% 65% 65% 65% 65% 65% 65%
8 x x 58% 58% 58% 58% 58% 58%
7 x x x 58% 58% 58% 58% 58%
6 x x x x 58% 59% 58% 58%
5 x x x x x 50% 50% 50%
4 x x x x x x 50% 50%
3 x x x x x x x 50%

Why don't you post an image of the matrices?
It would be more neat for sure
Something that you're going to miss with this kind of analysis is that hitting a board is a relative thing. On a board like QJ9 having a gutshot with some Kx probably counts as a hit but on a board like 942 having JTbdfd is probably going to count as a miss. I just think this methodology kind of misses the vital part of things that your equity is relative to your opponents range, if you've both "missed the board" a lot in the classical sense then maybe you need to rethink which hands have actually "missed". I don't say this to be snarky, just trying to point you in the right direction because board texture insensitivity is a problem that people have as high as 500z so if you get a hold on this early and learn to contextualise your hand class relative to what it is possible to have on the board you'll be in great shape.
Thank you. That's a great point. No snark detected. I tried to adjust for that actuality in my analysis: part of the reason that my "hit the board" deviates from Flopzilla's "hit the board," but even so, I agree this analysis is of limited value and a small part of the big picture, but still helpful for me as an exercise to go through and really get a sense of what percentage of combos would V potentially continue with here, as a starting point, thinking in terms of fold equity primarily. And yes, absolutely needs to be measured against sensitivity to board texture and weight of hands in Villain's range. Working on it! Happy New Year! And thank you for all you contribute here!
Thanks, always nice to hear that people appreciate my posts, happy new year to you also
