  plang: Certainly one of his best games was his nice attacking win over Khalifman in the 1997 russian championship which was voted 4th best game in Informant #69 but it is not included in this database.
Apr-05-07  wordfun: He obtained his GM title in 1990.
May-29-07  Vash854: Actualy in Russian the second e has 2 dots over it which is pronounced like Semyon (roughly), but in English they don't have such a letter so they write Semen (I carry the same name btw).
Oct-22-08  Karpova: Hans Ree in "One Hundred Percent Chessplayer" from December 1997:

<Dvoirys had been in Leeuwarden before and once he had thrown his shoe through the tournament hall after a defeat. He always came with a few companions and this time his companions had told the Leeuwarden organizers that during a tournament in France, a few weeks earlier, they had worried about Dvoirys, because they had noticed that during the night he had disappeared. It was only after a long search that they had found him, in the woods near a hollow tree where every day he had been hiding food, picnicking in the middle of night.

As long as Dvoirys was doing well in the tournament we noticed nothing peculiar about him, but in the seventh round against Bosboom he suffered the first of three consecutive defeats and in despair he broke a block of chocolate in to little pieces, threw them all about and then went to collect them, searching under his own and his neighbor's table. They were quite surprised when, in the heat of battle, they suddenly found another player crawling under their legs. "Gentlemen please, serious games in progress!" is the traditional arbiter's call to order, but the arbiter was speechless and anyway, his words would have been powerless.

After losing to Lobron in the last round, Dvoirys kneeled and beat his head three times on the floor with great force. I did not see it, for I was outside the building smoking a cigarette - yes, Americans, the anti-smoking brigade has reached our shores, but in defence of the rules committee it has to be said that we played in a museum among paintings of seventeenth century masters - and I barely saw how Dvoirys came hurrying out of the building at full speed only missing hitting a wall of the Chancellery by sheer luck before disappearing out of sight.

The chief organizer told us that once in Russia Dvoirys had beaten his head until it bled with his opponent's queen that he had just captured. "This is not quite true," said Russian grandmaster Gleizerov. "It was a knight. The knight is very sharp in Russia. His behavior has to be explained by the fact that he is a one hundred percent chessplayer. Chess is his life.''>

Feb-22-09  MarvinTsai: Nice sharing, <Karpova>, considering this game: Dvoirys vs Wang Yue, 2007 , he must have been quite upset at the end.

  Stonehenge: Russian pronounciation has everything to do with where the emphasis lies. For example Roman is pronounced as Raman, with the emphasis on the last a. The second e in Semen is actually a 'jo' (jolka) -no, not 'djo' as in English. In spoken language it's something like Siemjon -jon *not* being pronounced as John.
Jul-05-15  offramp: A tournament in his honour:

The Dvoirys Always Open.

Nov-02-19  botvinnik64: Strong theoretician in the Sicilian. Look at his earlier games against some heavy-hitters from the USSR.
