Did I see somewhere that the PLO registration will open while the main is in play on Saturday? Won"t that lead to half the field being blinded out while queueing to register for the following day?
As mentioned elsewhere, with the cap at 50 this will surely sell out in no time - especially as many people will already have planned to be there on the Sunday.
Part of the reason for the side events, were to ensure players that had made arrangements for the whole weekend, had an event to play on the Sunday should they bust the main event.
As seems to be the norm with APAT events these days, everyone wants to play everything, and demand far exceeds the available number of seats.
Registration opens to allow players to reg as they get knocked out of the main event, but as it is an open event, we cannot stop any players from registering once the poker room is taking payments.
