Monday sees Simon Whitlock enter the fray when he is involved in a group that includes Dutch youngster Mike van Duivenbode, World Championship runner-up Kirk Shepherd and former UK Open semi-finalist Alan Tabern.
There will be a further international feel on Tuesday when German Number One, Max Hopp will headline a group that includes in-form Belgian, Mike de Decker; as well as Keegan Brown who will be taking time away from being a key worker with the NHS to compete alongside Conan 'The Barbarian' Whitehead.
