In most formal game mixes, Crazy Pineapple is played Hi/Lo split with the 8 qualifier.
My thoughts on it generally will be that it will induce action, as players with three low cards are more likely to enter the pot. It also encourages ditching high pairs for low straight and flush draws because of the additional lo side equity.
I think it would be a fun action game, but tighter players will find it pretty boring and high variance.
I assume that for the low element both hole cards MUST play? The alternative is everyone with an Ace will be chopping an ungodly amount of ways and times on most qualifying boards.
