A new sub-page on Cork Congresses has been added to the Tournament series page here.
This event, which started in 1993, was originally called the Cork City Congress, presumably to distinguish it from the Cork Chess Congress series that ran from 1983 to 1990. (There was also an earlier 1st Cork Weekend Congress in 1977.) [See update below.] Since about 2002, the new series has been generally known as the Cork Congress. (All rather confusing!)
The new page here provides links to all known games from the new series. These include 88 games (pgn) that are not in the ICU games archive, as of the date of this post, including 31 from the 2008 event and 41 from 2009 (downloaded some time ago from the Cork C.C. website, though apparently no longer available there). [See update below.]
Update, June 1, 2020: David McAlister has corrected the history of the previous Cork Congress, and has provided one extra game, from 1994, for which many thanks. The previous series started with the 1977 event, resumed in 1984 (so there was no 1983 event), and ended in 1991.
