Well this is one for the ages . The youngest chess GM & he's shattered a record which stood for 19 yrs .
Meanwhile , I did some cursory research , Paddy . I checked if there were any Irish GMs in chess . Turns out there's one . Except he's of Russian origin settled in Ireland . Also turns out there's nobody of Irish origin in the list of the first 250 GMs as ranked today ( in fact there's nobody of Irish origin in the first 500 too ) .
