I suck at badugi and 2-7 since I never studied them nor play them a lot. I know the basics but I'm not good against decent players that know the game well.
I can't spot the fish very well in those games besides the ones that raise or play every hand. Maybe the ones that go for a painted badugi or folks aiming for a 10 low in 2-7? Don't really know.
Before I check out, I might try to work on those if folks are still playing them in a few years, lol.
Too bad folks don't play A-5 anymore. I really enjoyed that one.
