TWIC reports that Svetozar Gligorić died today in Belgrade. (Born 2nd February 1923, Belgrade.) He was one of the household names in world chess when I was learning the moves, so for me and I’m sure for many others this is the end of an era.
He visited Ireland on at least a couple of occasions. One was for the Dublin zonal, 1957, tying with Benko for 2nd-3rd behind Pachman. The other occasion I’m aware of was his series of four simuls in February 1971 (Cork, Wexford, and two in Dublin): see the Simuls page.
