FWIW Here’s a game which is popular in my area... At my 1/2 cash game it is only allowed extremely late at night, and only for the last round before the diehards leave, but I know of other games where it is played regularly. (I avoid them.) It seems designed to make you lose everything you worked hard to win over the previous 6-8 hours.
The game is usually called “Rosie” here, but the formal (?) name is Rose with a Tail. No idea why... Maybe the board looks something like a rose? I dunno.
It’s basically Triple Board PLO8, with two more cards dealt to the left of the two flops (in addition to the two turns and rivers to the right) to add a third board. Both flops are revealed simultaneously, then all the turns, then all the rivers, with betting rounds both preflop and on each street.
No one sane raises preflop, unless maybe they are holding A2345. Still, it sometimes possible with all these cards in play to somehow not make a low.
To make things truly ridiculous, people usually add a buy-or-trade option on as many streets as the number of players and cards in the deck will allow.
It’s usually played with a $1 ante for the entire table (no blinds), and buy/trade options of either $2/$4 or $5/$10. The general thinking—to the extent there is much strategy here at all—is that you are a fool not to buy as many cards as possible before the river, since your winning hand on the flop is almost always going to become worthless later. On the river, trading or standing pat is occasionally right if you can’t improve.
Betting occurs after each buy-or-trade. If the number of cards are short, sometimes the table will agree to everyone buying a community card instead. There is some dispute as to what happens if someone does not have enough left to buy-or-trade; sometimes people agree to a “free” card for everyone, sometimes not.
Needless to say, it is rare that someone does not have the wheel or the top full house. But it happens. The strategy, to the extent there is any, is mostly about how soon to give up and how to get others to keep putting money in when you have it. It’s very hard to get a bluff through. Like most PLO8 variants, this is a game where getting quartered can be disastrous, and you really want to scoop.
A truly degenerate game. Is this a Hudson Valley-only thing, or have people played this elsewhere?
