It wasn't that long ago that I mentioned that Yuri Averbakh became the first grandmaster, past or present, to reach 100 years of age. Alas, news comes that the Russian GM and erstwhile Candidate passed away on Saturday. Here are some tributes:
Averbakh was not only an accomplished player, but a theoretician, endgame specialist, writer, chess historian, international arbiter, and administrator as well. As far as I know, he didn't engage in correspondence chess, and he wasn't involved in computer chess; other than that, he made significant contributions to every aspect of our game.
Rest in peace.
