zanzibar: There's a memorial tournament held for him, here's a link to FIDE's 2011 version of it:
He was supposed to play <URS Cup (1970)> but didn't, for some reason.
His Russian (Cyrillic) name is given as <Дорошкевич> and it's curious that:
1) Google translates it as <Darashkevich>, which is odd.
2) <FIDE> (and <CG>) translates it as <Doroshkievich>, since there is no "и" between the "к" and "в".
I would translate the name as <Doroshkevich>. Maybe there's some subtly I'm missing, but there is an alt in Google translate that matches, and none of the google alts end with "kievich".
The Memorial tournament uses the name <Doroshkevich>.
Anyways, his FIDE card is still active (#4104447):
and he last arbitrated (chief arbiter) this 2009 tournament:
So, is Doroshkievich still alive? If so, then who is the Memorial Tournament named after?
BTW- Here is a scoresheet of a Doroshkievich loss to Karpov, I think in D's hand(?):
