If anyone is thinking about playing OTB in Ireland i can say that i attended the tournament and the playing conditions were very good. The other sections (open,intermediate and junior) welcomed players from Luxembourg, Russia, Poland, England, Philipines and a few other countries (i didnt see the full list).

If the Irish Champs 2009 is too much of a wait for you then the other 2 international chess tournaments in Ireland are Kilkenny (Nov) and Bunratty (Feb. Last year GM Peter Svidler played at Bunratty and usual entrants include GM Luke McShane and GM John Nunn.
