The entry list is in two sections:
registered players
pre-registered players

This year the tournament limit is 84 to allow some headroom for EGF Grand Prix players who might want to participate in the later rounds.

Registered players have paid in advance and are guaranteed a place.

Pre-registered players are in a queue by date of pre-registration.

As soon as you choose to pay you are moved to the registered players list. Once the number of registered players reaches the tournament limit the pre-registered players list becomes a waiting list.
