Here it doesnt really matter. In both cases i will keep the 9, because a 6 tri isnt that strong as a 4-5 tri would be....

Can you give me a time, where that hand happened? Now i think 23T i almost always treat as a 2card draw. 238 i almost always keep. 239 is the borderline hand wether i draw to 23, or play as a 239.

Sometimes we can keep 23T, when we know that our opponent has a rough badugi (for example sb opens, we defend bb, sb pats...There i might draw 1. He will have all the badugis, and with a T badugi if we make it we will beat most of that)

The reason is that with a T badugi we will very likely win against a predraw badugi range.
If opponent is pat from the beginning his range will be:
K badugis 31%
Q badugis 23%
J badugis 17%
Thats 71% of his range!
Also he will have 12% T badugis, and if we make a smooth ten, we weill beat those also.

Yes, there is a chance that we will be drawing dead against a 8-9 badugi, but in the longterm i think here the correct way is to take 1, try to make a rougher badugi sooner.

It would be completely different if let's say we open UTG. CO and BTN flats, and SB 3 bets, we both call and SB pats. Here SB shouldn't have all of his badugis. (although some players tend to play all badugis here also). Against a stronger range we will be doing better by drawing to a smoother hand. Additionally, because it's multiway even if we make a ten badugi which ends up being good, CO or BTN might outdraw us.

You are right :(
