The definition of a PRO is somewhat different in Belfast, you need to be long term unemployed, wear only tracksuits and own a variety of garish jewlery(usually indicating your political persuasion) purchased from cash converters, also an internet connection is required.
These PRO's tend to be well known at the live tournaments purely because they tell you they are PRO's as they stare you down with intense menace. I played at a table with one such pro named "STICHES" and the only reason I knew his name was because I could clearly read it on his heavily tattooed neck

HI mate i played a game in belfast a few weeks ago
£50 buy in
it was in the HIDEOUT pub in Donegal Pass
everyone of them was PRO's
and there is no chance im not going to say there not

but it was a great laugh and the banter was just as good as in glasgow
