Very little detailed information exists on club championships down the years: most of these have been fairly informal tournaments with results not reported anywhere. But there are exceptions: Phibsboro C.C.’s 2010 championship was FIDE-rated, which I think (open to correction here) is the first time ever for an Irish club championship. It was a 7-player all-play-all, and a relatively strong event (1st Francisco Canosa Sierra, ahead of Stephen Brady), well worth covering.
Being FIDE-rated meant that most of the data required to reconstruct the tournament is available from the FIDE tournament report, and Mick Germaine, who controlled the tournament, provided the extra missing information (on walkovers). The report has been added to the Tournaments page.
