Jan-10-10  Billy Vaughan: Onischuk is tearin' it up at the World Team Championships, with 4.5/5 and wins over Harikrishna and Smirin.
Jan-11-10  BTO7: No doubt !!! Great job Alexander !!! Way to represent for us here cheering you guys on in the United States !!! 3 rounds to go take it to them :)
May-28-10  laskersteinitz: Onischuk is in the Live Rating List: Has he ever broken 2700 FIDE before?
May-28-10  laskersteinitz: Apparently not...his peak is 2699, which he has reached on three occasions (
Jun-01-10  redribbon3700: Today he should be on the list as a 2700 player on FIDE! Great job.
Sep-03-10  ketchuplover: Happy Birthday Mr. Onischuk.
Premium Chessgames Member
  HeMateMe: Congratulations to Oni, winning this tournament. He is 2006 USA champion, and played board 3 for the USA in the last Olympiad.

  sisyphus: I saw Alex Onischuk today, at the Fairfax Open, a two-day Class B swiss. I knew he'd lived here in Manassas, Virginia, for quite a while; but he'd never appeared at local events, even big ones like the Atlantic Open or Eastern Open, which always attract some GMs.

Anyway, he entered this weekend tournament, just four days after finishing the World Team Championship in China. He had to be jet-lagged.

And he wound up equal first with 3.5/4, tied with IM Tegshsuren Enkhbat.

Sep-03-12  wordfunph: "The first time I played against Kasparov was in blitz games. I won with black, and thought I'd do pretty well. Then I lost 25 games in a row. I was already a GM, and didn't think I could lose 25 games in a row to anyone!"

- GM Alexander Onischuk

happy birthday, "The Rock"!

Sep-09-12  ketchuplover: Thanks for your olympiad effort :)
Oct-10-13  twinlark: Interesting that no one seems to have noticed that Onischuk's rating has escalated on the basis of the mistaken notion that he defeated Dominguez-Perez in the World Cup.
Jan-13-14  offramp: Superb player.
May-29-14  ketchuplover: Congrats on being the 2014 USCF GM of the year Mr.Onischuk
Jun-11-14  john barleycorn:


Jun-12-14  twinlark: Interesting decision. Webster performed better but Texas Tech got the nod. Did Susan Polgar's presence at Webster affect this decision?

And did he really have an "incredible year" as a player?

Apr-07-17  ketchuplover: down goes nakamura!
Apr-07-17  bubuli55: I like his chances. GM Onischuk may well pull off a big come from behind win.
Apr-10-17  PhilFeeley: Who is he married to? From the picture here, it looks like Jennifer Shahade, but that can't be right (or can it?).

Premium Chessgames Member
  HeMateMe: his wife's name is Olga


she does resemble Shahade, a bit.

Jun-16-17  ketchuplover: Best wishes at the world team championship
Sep-09-17  ketchuplover: Good luck in round 3 of the world cup

Sep-03-18  diagonal: <=1st (2nd on tiebreak behind Magnus Carlsen) at the Biel Chess Festival in 2007>

The tie-break decision was a <speed play-off> after a fifth and final Armageddon game:

This video gives you a good impression of the Biel play-off final from 2007 between young Magnus Carlsen and Alexander Onischuk (who had won the B-Group at Biel ten years before in 1997 in a six players double round robin with an incredible3.5 points leader margin).

The two rapid games and two blitz games were both drawn (the video shows extracts), there had to be in the play-off an ultimate Armageddon game, the integral broadcasting in the video shows this cruel decision, won by youngster Carlsen.

In the interview, Magnus Carlsen pays tribute to Alexander Onischuk who had to win the Armageddon, Carlsen pointed out that having black (= a draw means winning the whole tournament) in Armageddon is widely considered to be an advantage.
