In Crazy Pineapple, 1 card is indeed discarded after the betting on the flop, so before the turn comes.
During our APAT event in Belgium last month, we had Crazy Pineapple as our opening side event.
We played it No Limit.
It was the very first time that in Belgium a casino hosted a Crazy Pineapple event, and players liked it very much.
A lot of the had to ask us the exact rules, but they joined and liked it.
I believe IrishTom fitted this into the WCOAP schedule because we were planning to have it in Belgium and he thought it would a good idea to have it as well... And I"m very looking forward to playing this event
