hi man
I guess sending a PM message to Marchewa would be a good idea, he's the prince of Gdansk as far as I remember
Gdansk is a great city, but unfortunately its not much visible on the vtes map in PL (I mean - not many people from there show up on tournaments, and we don't have much info of what's going on there). I can't give you much more info apart from what mirumo already said.
if you have a car or some spare cash for traveling by train, I'd suggest moving south to Bydgoszcz or Torun for some weekend and play over there, there's some game guaranteed if you get in touch with those folks (be prepared for some drinking in Bydgoszcz as well
)
