Maybe there was a mistake in the graphics, we should ask Dirksen about this :) But if he/anybody folds TT843 in this spot it would be a big mistake

With a bluff we target's Benny's T/J region but keep in mind that he still has all the strong hands in his range, pat 8/pat7, despite it's rare. So we need to be careful and choose the best blockers and low pairs are better. And 22 not only blocks pat 8s, but it also blocks pat Ts/pat Js (T7542, JT932, etc.) Despite some Jxxx2 prefers to discard (~J7542, J8752, maybe even J9432)

11:00 you mention schwartz should not call an A which is no different than having a T. What if schwartz had paired his 2, 4 or 7? I have seen in other videos that snow catching with these types of pairs can be ok sometimes.

Low pairs are generally better call candidates when both players are drawing, like 1:1, because then 22 is a better call then an Ace, since a 22 still beats all bluffs but blocks value from opponents. To be honest I don't really know which one is a better call against a predraw pat, 22/44 or an Ace. No difference, but 22 not only blocks value hands but it also blocks predraw snows (like 2227K, 44499, etc.)

In general for snowing and open raising and snow catching, in nl is it better to have more 8s and 7s compared to td where we want 2s and 3s?*
For snowing low cards are still much better. 22233 have a much better blocking purposes than 77788. But both hand is a mandatory, no brainer predraw snow. But lower cards/pairs are still better here (same concept applies than in 2-7TD)

24:00 should dirksen bluff the made qj? If bonyadi prs up or makes an A or K he may bluff and any better hand may chk back and just win or vbet and dirksen ends up in a crappy spot. Seems better for him to just bluff bet.
The problem by bluffing QJ against 1card draw is that then he will be massively overbluff, because he should have some predraw snows as well. But it's a good point. Not thinking about long term in this hand it would be better..Since he will never get bluffed and can get some better hands (J/Q) to fold. But i still wouldn't do it :)

25:32 becker only calls from the bb with a 1 card draw. I know in triple draw we cap our rng if we only call 1 card draws so we should generally always 3bet. Is that also the case in single draw?

No, 2-7 single draw is different. 3467 is a perfect hand to call. We don't want to face a 4bet, and also it's not a premium draw. BB will have a lot of weakdraws in his range, like T984, maybe even JT822 vs button, so for balance we need to have some call/1 which can be strong hands. And gutshots (esp. without blocker) is perfect for that, so 3467-K, 4568-K, etc.

*44:00 is it standard in 2-7nl to 4bet jam 60bbs?*
I think I already talked about thit. The 4bet jam 60bb is standard (as for sizings, since he doesnt wan't/can't raise less). But his hand selection is too exploative and he will overdo this if he does it with J7543. But J7542/J7632 is a standard shove (for 60bb) and even ~J8432 can be OK

With most of the hands we will be commited with our 4bet, that's why i think shove is OK. However there are some hands that can/want 4bet/fold, mostly snows, 3333-8, 22255, etc...To balance this out we can 4bet small with our monsters as well (pat7s, maybe pat8s), but these hands i rare, so i havent studied this spot in depth
