  Phony Benoni: "His only overseas appearance was at Tel Aviv 1966 where he finished 12th= out of 16. All his chess otherwise was played in South America."

The Warsaw 1935 and Stockholm 1937 Olympiads don't count as overseas appearances?

  Phony Benoni: I just submmitted this game to the database:

[Event "Olympiad"]
[Site "Warsaw"]
[Date "1935.08.25"]
[EventDate "?"]
[Round "12"]
[Result "0-1"]
[White "Betbeder Matibet, Louis"]

1.d4 d5 2.Nf3 Nf6 3.e3 e6 4.Bd3 c5 5.c3 Nc6 6.Nbd2 Qc7 7.0–0 Be7 8.Qe2 0–0 9.dxc5 Bxc5 10.e4 Bd6 11.Re1 Ng4 12.Nf1 Bd7 13.Bg5 Rae8 14.Bc2 dxe4 15.Qxe4 f5 16.Qc4 h6 17.h3 b5 18.Qe2 Nge5 19.Nxe5 Nxe5 20.Bf4 Nf3+ 21.Qxf3 Bxf4 22.Bb3 Kh8 23.g3 Bd6 24.Rad1 Bc5 25.Rd2 e5 26.Ne3 Bxe3 27.fxe3 Bc8 28.Red1 f4 29.exf4 exf4 30.Rf2 Qb6 31.gxf4 Re3 32.Qg2 Bxh3 33.Qh2 Qg6+ 34.Kh1 Qe4+ 35.Kg1 Re1+ 36.Rf1 Rxf1+ 37.Rxf1 Bxf1 0–1

I enjoyed the power and efficiency of Black's play, even if White may have made it a bit easy for him. 17...b5 is startling at first glance, but 18.Qxb5 gets zwischenzugged by 18...Nd4 19.Qd3 Nxf3+ 20.Qxf3 Ne5, when White must give up the exchange by 21.Rxe5 to save his bishop.

  al wazir: The <CG> database has six games between Jacobo and Julio, all ending in draws, none over thirty moves. Draw your own conclusions.

Are there any examples of IM or GM chessplayers whose children were also strong players? If not, that seems to argue that exceptional ability at chess is *not* genetically determined.

Milan Vidmar

Milan Vidmar Jr

are a GM father and an IM son combination.

Dec-27-06  Karpova: Thomas Paehtz and
Elisabeth Paehtz
Dec-27-06  Caissanist: I remember that IM Boris M Kogan had a son Michael Kogan who was one of the USA's top juniors in the 1980s. Michael gave up the game while still a teenager, though, and never got an international title.

Sibling rivalry seems to nurture strong chessplayers much better than the parent-child dynamic. There have been far more sibling pairs of titled players than parent/child ones.

Sep-04-07  wolfmaster: The Polgar sisters, obviously!
Mar-05-10  Caissanist: If anyone is interested, we have been keeping a running list titled siblings on the Ton Timman page, and a (much shorter) list of title parent-child players on the Raymond S Kaufman page.

  Fusilli: I was a teen playing the qualifiers of the Buenos Aires youth championship back in 83 or 84 and the tournament was at Club Velez. I was trying to focus on my game but there was this loud old man talking in the back. I politely directed a few mild "shhh" his way. Eventually, fed up, I turned to him and went "SHHHHHH!!!!" as loud as I could.

He stopped and I didn't hear him again. Only days later did I find out it was Jacobo Bolbochan, when someone told someone else, pointing at me, that I had shushed Jacobo. (It was amusing to them, I guess old Jacobo was routinely loud in the playing hall.) I think I was too young and careless to have felt embarrassed. I would today, of course.

Jul-18-12  Petrosianic: When the only Notable Game they can find is a draw with Ivkov, that's a sign that you might not have had the world's most illustrious chess career.

There's a draw with Pilnik in there too, they could have stuck that in, at least.

  Gregor Samsa Mendel: <Petrosianic>--Take a look at this one: G Szilagyi vs Jacobo Bolbochan, 1966

The database has a victory against Najdorf, but it does not look that impressive: Jacobo Bolbochan vs Najdorf, 1945

Jul-18-12  Petrosianic: White doesn't seem to have any advantage at the end, in fact Black may be a shade better. It looks to me as if Najdorf overstepped. But on the other hand, I don't think White is losing at the end, so even a shoulda-beena-draw with Najdorf in 1945 should be good enough to make Jacobo's Notable Games List.

Dec-26-13  waustad: <GSM>To get on the notable games list, a game has to be in several collections, if I'm not mistaken.

  Fusilli: <Gregor Samsa Mendel: ... Take a look at this one>

I just added that one to one of my collections.

  Gregor Samsa Mendel: <Fusilli>--It seems that our adds were sufficient to get this game into the notable games list.
