[what is this?]

Grandmaster (2019).

FM (2009); IM (2013).

Bobby Cheng gained his FM title when he became the 2009 U12 World Youth Champion. He became an IM when he won his 3rd IM norm at the 2013 Sydney International Open.


After winning the 2009 U12 World Championship, he won the Australian U18 championship in 2010 and 2011, and then came 5th in the 2011 Oceania Zonal, with 6/9. He came 5th in the 2010 Victorian Championship, won the 2011 edition of that event, came third in 2012 and won the 2013 Victorian Championship with 10/11. In January 2014, he placed a slightly disappointing =5th at the Australian Championship with 7/10.

Classical Tournaments

In June 2010, he won the Victorian Open on tiebreak from Erik O M C Teichmann and a half point ahead of GM David Smerdon. In October he came 4th in the Melbourne Cup Weekender with 6.5/9 and in December 2010 he came in second behind Stephen John Solomon at the Australasian Masters held in Melbourne and =5th at the Canterbury Summer Swiss held in Melbourne. In June 2011, he came in =3rd at the Victoria Open with 5.5/7 and in July 2011, he won the category 2 George Trundle Masters in Auckland, New Zealand with 6.5/9 thereby gaining an IM norm. In October 2011, Cheng took 2nd at the Melbourne Cup Weekender with 7/8, his draw with the winner, GM-elect George Xie Wendi , marring the latter's otherwise perfect result. In December 2011, he came clear 2nd in the 2011 Australasian Masters with 6.5/9 (+6 -2 =1) behind IM James Morris and followed up by starting 2012 with 6/9 in the Queenstown Chess Classic (2012) and 5.5/11 in the Australian Championship.

Since then, he came =3rd at the Ballarat Begonia Open, scored 5/9 at the 2012 Doeberl Premier, placed =4th at the 6th Sydney International Open, =1st at the 2012 Victorian Open and 3rd at the 2012 Victorian Championship. He represented Australia at the World Youth U16 Olympiad, playing board 1 and helping the Australia "A" team to 8th place. He put in strong performances in the Victorian Teams competition (4.5/5) and won the Box Hill Open in October with 6/7. Cheng finished 2012 with a strong =1st placement at the Australian Masters, scoring 6/9 and started 2013 with a stunning outright victory in the Australian Open 2013, with 9.5/11 (including a first round bye), a result that earned him an IM norm, nearly 50 rating points and a position in the top 10 in Australia. In 2013 Cheng earned his 3rd IM norm - and the IM title - at the Sydney International Open, scoring 5.5/9. Since then he won the Victorian Championship with 2 rounds to spare, scoring 10/11.

He was 2nd at the Australian Blitz Championship 2015 with 8/10.

Team events

Cheng played board 1 for Australia at the U16 Olympiads of 2012 and 2013, the team placing 8th and 9th respectively.


Cheng's highest rating to date was 2539 in 2020/21.

  Jonathan Sarfati: Yes, excellent result: I think the first Kiwi to win a world champ

On ChessChat, a post said:

A special thank you to Bobby's New Zealand coach, FM Ewen McGowen Green, who not only got Bobby on the right track since 2005, but also have been supporting and helping Bobby after we left NZ. Even to the last round of this tournament, Bobby was still practicing his planned opening lines with Ewen on ICC. It might be sad for the Kiwis to lose young talents like Raymond Song, Jack and Harry Ruan, but I think Bobby's victory is in part a New Zealand victory as well.

Premium Chessgames Member
  Richard Taylor: Yes Ewen and Bruce Wheeler of ACC (Auckland Chess Centre) coached him. It is part a NZ-Australian and a Chinese Victory! A really international world now!

But we need more of his recent games up on here not only all my wins! (in standrd chess I had about 3 wins and one draw v Bobby - but he was a tough opponent even when he was 8 or 9!!!) He played at least one great game at the World Juniors... Mind you players these days are paranoid about showing their openings - but a confidant player lets SOME of his/her secrets out though!

How is Harry Ruan doing?

Premium Chessgames Member
  Benzol: I can see Ewen Green dancing in the streets soon.

  Richard Taylor: Herman shouldn't have lost that game Paul - Bobby was a bit lucky Herman blundered. 41 Nf3??. (Position was = I think). But once he lost material from the opening Bobby certainly played well and put pressure on Herman.

But Bobby is doing well in the Australian Masters right now (12/12/2010).

From his results, it looks as though he will get an IM norm. He may become an IM this year or next when he will be 15. That is pretty good going.

Apr-01-11  ozmikey: I recently came back from a trip to Melbourne with some of the kids from my school, who were taking on the students of Melbourne High in a series of sporting/cultural contests. Although we eventually won the chess (it was a 4 player each side Scheveningen event), Bobby was absolutely unstoppable for them. Won all four of his games and was razor-sharp in the post-game analyses. This kid is frighteningly good.

I've sent a correction slip to admin.

Premium Chessgames Member
  Benzol: Thanks <twinlark>.


Jan-12-13  ozmikey: Bobby is a point clear of the field heading into the last round of the Australian Open, ahead of several grandmasters:

Jan-12-13  twinlark: So he has at least an IM norm, now?
Premium Chessgames Member
  Colonel Mortimer: I achieved a draw with Bobby in standard time controls. A pathetic performance by myself as I had a winning position out of the opening.

But God he was sharp (I think 9/10 years old when I played him - actually probably younger).

  kingscrusher: Video annotation of Bobby's game vs a Top 100 GM in the Australian Open 2013 :

Jan-14-13  Wild Bill: Thank you, kingscrusher. I watched it last night on your channel. I was thinking, "Wow! another 15-year-old named Bobby."
Jan-21-13  waustad: Chessbase has some coverage here:
Jan-21-13  waustad: Cheng already has at least 1 IM norm. I'm not sure if he played the required number of titled players for this to be another IM or possibly GM norm. If so, it hasn't been submitted to FIDE yet:
Premium Chessgames Member
  Richard Taylor: He is an IM now. Congratulations are sent.
Premium Chessgames Member
  Richard Taylor: Soembody needs to upload more of his wins / games vs. stronger players / more recent games etc on here.
Mar-07-17  PhilFeeley: [Event "9th Batavia Chess Tournament"]
[White "Baron, Tal"]

[Round "9.2"]
[Result "0-1"]
[Date "2017.03.05"]
[WhiteElo "2544"]

[PlyCount "48"]

This secured his GM norm at the recent Batavia tournament. I'm not sure what the threat is at the end of this, although I understand black is better. I'm just not sure how.
