200/400 Badugi hand

[groth911t]

200/400 BOTE at the bellagio, full table.

Folds to the CO, who opens, Button folds, I threebet from SB with a24, Miami John calls from the BB, CO calls, everyone draws 1.

I lead out after catching offsuit paint, John calls, CO raises, call, call. 1, 1, pat.

I catch (a24)9. I c/r, John call, CO threebets. I call, John calls. Everyone stands pat.

Checks to the CO, he bets, I fold, John calls.

The CO is a NL player who seems fairly new to the mix games, but pretty tight in badugi. Miami John seems to know badugi very well.

I think the first two streets are pretty standard (though maybe some wouldn't lead out after bricking the first draw). I'm wondering about after the second draw (where i've heard everything from just c/c/stand pat to four betting), and on the river, where, IMO, i'm hardpressed to have either player beat. I'm wondering what some more experienced badugi players do on both streets. I'll post the winning and losing hands later.
