I tried to address this earlierI think but was probaby unclear.

2-7 and badugi have one major difference. if you have the best draw in badugi and you and opponet both brick the river you win. That's clearly not the case in 2-7.

Here's a good exercise, with 1 draw left how much equity does a 3 card 6 have against a 3 card 7 if both opponents draw 1 (badugi not badeucy). In 2-7 how much equity does 2347 have vs 8763 if both people draw 1. I think answering that will help you unwderstand why having a better try is more important than asliughtly smoother 3 card draw in 2-7

In badugi, you only have 4 cards, so a better tri is more likely to hold up. You are also talking 3 draws left here versus 1 draw left in your example. It is much easier for someone to make a badugi to beat the 6 high tri in the posted hand.

There are interesting situations in a split pot game like this. Lacking badeucey solvers, I am still skeptical about what is apparently standard wisdom to draw rough in TD to keep a better tri.

I still think you should try and answer the question as it will help illustrate why 356 is better. I think you are both under valuing 356 for the badugi and massively over valuing 357 vs 356 for the 27 hand.
Remember that in baduecy, your opponents are going to break off 50% of the badugi they make on the first and often second draw as well.

I agree that badeucy has tons of interesting spots and some are very complicated, its what makes it such a great game. But this kind of reminds me of a lot of super razzdeucy live hands I've played. I'll open someone wil call or 3 bet then go into the tank deciding what cards to keep. Have to ask wtf are you thinknig about, take the 3 lowest cards that are a differnet suit and get rid of the rest. Baduecy is the same. Take your lowest cards that are a differnet suit and try to make a good hand.

Here's the other thing you keep mentioning, what happens when we catch the 2 wouldnt we rahter have 2357 vs 2356, sure. Well sometimes (more likely) we catch the 8 and woudln't we rather have 3568 then 3578?

So if you were dealt 2s3d4h5s7s you would keep the 234 tri and draw 2? I assume that it isn't even worth think about, like in razzdugi?

i honestly don't know if this is a serious question or not.

Let me rephrase, if you are trying to decide which card to keep you take all of your available options (hence different suits) and keep the lowest ones (almost alaways but the expctions arent worth talking about)

why would you break a lock hand?

OK, so as tris to keep predraw, 345 is better than 346, 347, or 357?

yes

This game in general is far easier than most make it out to be. I’m not going to start a strategy post on it, because I want people to continue playing it poorly for as long as possible. But I will say some things here, so that it’s more hidden.

*firstly, 356r is dominating 357r. You’re never taking the 7 here, because villain could have 347r and dominating you. Why would you ever put yourself in that spot vs an opportunity where you’re dominating them instead with 356r vs the 347r!?
*on the first draw you’re never in a million years keeping that 7 for value. It’s tempting you like fkn medusa. Go for the scoops. That is the idea of split games. When you keep the 7 in scenarios such as this, you’re setting yourself up for an ability to only 1 try at the essential card you need. By mucking, you double those chances. I muck the ****ing 7 on draw two also. It’s not helping you scoooooooop! So it needs to go away.

Without the 7, you cannot make a "nutted" hand for the 27 half.
So not sure about your scooooooooping chances.

Haha I was grumpy in this thread (but correct!)

A factor I haven't seen mentioned -- the hands needed to scoop at showdown will probably be quite weak. Your opponents are loose. It's button vs. blind[s]. You're discarding two cards to a seven.

Seems like a very strong tri plus a good draw at a lowball 9 or even T on the later draws is a legit scoop threat. (You can readjust priors depending on who calls you and how they draw.) You'll probably have plenty of outs to scoop without needing to make a 7 or 8-low. I don't know this game so I'll leave it to the experts, but that seems to shade things toward pitching the seven.

Now for real fun I hope you caught 4 and a king on the first draw.

I get the rest of the reasoning but I don't understand this comment. What does that actually mean?

Not sure I understand it either.
You at least need a 7 to make #1 to #4 in 2-7.

I don't know how else to say it - sure at showdown its relevant if you have a 7 in your hand, but that's not what "key card" means to me. "key card" means something that affects your strategy and decision making with streets left to play. If you have a 2 in your hand or not will have a huge effect on your decisions throughout a 2-7 hand, the presence or lack of a 7 won't (until the river).

There's only one "key card" in 2-7, all the other cards are relevant but not "key". Maybe its just a semantics thing? I've never once been on the first draw in 2-7 and thought "damn if only I had a 7 in this hand instead of this 6" or whatever. Its just not that big a deal.

Interesting thoughts.

Not a big deal indeed I guess, but in TD2-7 I would still slightly prefer to open 237 rather than 236 (and even 235).

237 > 236 in TD but not Badeucy makes intuitive sense. The six contributes to a Badugi hand that, at showdown, is substantially better than the corresponding version with a seven (whether 6-tri or 6-badugi). In 2-7 lowball, the six only helps make a 7-low if you also draw a seven, so you might as well have chosen the seven in our hypothetical.

And obviously a pure TD 86 is better than an 87, 96 better than 97, but that probably means less. Wouldn't it be fair to say the gap between a TD 7 and a corresponding 86 is much greater than between an 86 and corresponding 87?

I don't have a feel for Badeucy at all but I take it a 6-dugi is much much better than a 7-dugi, maybe to the extent a TD 7 is much better than an 86?

That might be unclear and I know there are holes in my thinking, so please, fire away.

Re: semantics -- seems like a question of degree (how key is a "key card"?). Just wanted to make sure I learn what is to be learned here.

Concrete question on the same topic: In pure TD, which is better: 762-77 or 762-66? A little better or a lot better?

76277 has to be leaps and bounds better

you sure like it a lot more going for b3b ott or otr when you've seen 77 already with a #4

there's other reasons i think are also very impactful and more frequent but i think that's probably one of the more obvious ones at least
