This hand for a study session with hands shared after the fact, 6 handed cash game.

Predraw: CO opens AKQJ9, btn calls with 97654r, sb folded KK (standard, right?), bb defends KQ765 (too loose?).

1st draw: bb draws 2 to the 765 with 2 flush (thoughts?), CO draws 3 to the royal (good?), bb tosses the 9

Flop: bb checks with 77556 (lead?), CO bets with JJAQ9 (bad?), btn calls with 76542, bb calls.

2nd draw: bb tosses the 6, CO tosses Q9 (better to keep AQJ?), btn tosses the deuce (better to have raised and pat?)

Turn: bb checks with 7755T, CO checks with JJAQ3, btn checks back with 66754 (better to bet as semi-bluff?)

3rd draw: bb tosses the T, CO tosses Q3, btn tosses the 6

River: bb checks with 77552, CO checks with JJAT3, btn bets with 76542 (too loose for value?), bb calls (ok?), CO folds. Showdown: chop

Sixes qualify for high?

Either way I’d reraise on button with 7654 but easier if pair of 6s or 7s qualify

Well, my first thought is that the BB is way too passive with two low pair. I guess you should dump it in scary action or play it aggressively if you think it's best or the pot is big. Giving cheap cards for one big pair to draw seems like a disaster. As a beginner at this it's hard for me to know how to interpret a 2:2:1 on the first draw. OTF it feels marginal between leading and folding.

Disclaimer: I'm not good at this game. Eager to hear other thoughts.

99+ for high qualifier

Bb should fold preflop imo.

Lots to talk about postflop but let's start with there being a very strong case to pat the 76542 after everyone draws.

Patting a made low quickly can clean up the whole pot by getting one pair, weak low & hi draws to fold. More convincing if 3b pre but still sound.

Ok that's the most notable thing I've heard this hand. In split pot games I'm always inclined to go for the scoop and I figured one of the worst 7s wasn't much of a low anyways. Also very helpful to know 7654 is a re-raise pre.

This hand is a catastrophe from all players.
C/o open is marginal but okay. Button should then 3b and BB should fold to the single raise let alone both.
As played, BB should lead his 2p, then c/o should check his nothing or call the lead, and btn should bet if checked to or raise if bet into intending to pat. Button's decision is probably the MOST clear of anyone's. c/o should draw to the royal again IMO
Turn BB should probably bet again and then everyone else should check.

On the river, if 66 qualified (which is a far better rule), the 2 pair should bet. It will look pretty bluffy/low-y and get called by any qualifying high. With 99 qualifying check is fine since they can't make accidental pairs to call with except AA. Btn bet again is probably fine in a 66+/high scoops if no qual game, but maybe is a good check with 99/all chop.

Archie is nothing like any other split game. It's super hard to make a 2-way hand so the way you scoop is by beating another player going the same direction as you.

Archie remains a great game for the mix because people play it using the rules of thumb they have learned from other split pot games, which creates a huge potential skill differential. Archie structurally favors high hands, and low draws against made hands have dramatically less equity than in any other split game.

Sixes qualifier is the nuts. Nines qualifier is almost a bad game, unless many people are new to it.

Why do you think this makes such a difference? I can't imagine something less than a pair of 9s would ever win anyway.

It matters some particularly with 4567 hand we have

The Sixes qualifier creates opportunities for busted low draws to make payoff pairs which makes river action more consequential.

Maybe he thought the nuts would be a more exciting answer though

Yeah 66+ is much better. Consider a Hu pot between 2 low draws without aces.

Televise dat chit

i think opening AKQ is worse than bb defending 567, especiallfy if your gonna botch postflop that badly

Given that he played it as AQJxx ccc. does this mean that's even worse to open? Should he have drawn to AKQ instead of the AQJ 3-flush? Which street is his biggest single mistake?

Personally, I open fold CO's hand. Drawing two to a hi-only flush isn't that appealing. BTN should absolutely 3-bet. Any 4-straight low hand is insanely strong. BB should probably fold. preflop.
