The FIDE record ratings page, recording the all-time peak ratings of Irish players, has been updated to account for the April 2020 rating list.
I expected that there would be no change this month, given world events. But in fact two players reached new personal highest ratings:
Tarun Kanyamarala 2376 → 2384, 18th → 16th;
Killian Delaney 2302 → 2303, unchanged in 36th place.
Tarun Kanyamarala thus recorded a new personal record in at least the last seven lists. This month he moved past Colm Daly and Mark Orr, both with peak ratings of 2380.
