Sep-25-05  who: This guy's career wasn't short. Can anyone add more about him than is in the bio.
Sep-26-05  paladin at large: <who> Capablanca wrote about Opocensky 1939 in the context of the chess olympiad: "Opocensky has a marked tendency to complicate the game, and he is not intimidated by the reputation of the opponent".

Feb-07-09  nescio: Usually Boleslavsky is mentioned as the originator of de the Sicilian with e7-e5 (M Yudovich Sr. vs Boleslavsky, 1942) and as the player who made it an important system. While he certainly deserves the credit, great strategist that he was, I have heard rumours that Opocensky experimented with it as early as the late 1930's. I have never seen games to back this up though, the earliest I can find is Lokvenc-Opocensky, Prague 1943:

[Event "Prague"]
[Site "Prague"]
[Date "1943.??.??"]
[Round "3"]
[White "Lokvenc,Josef"]
[Black "Opocensky,Karel"]
[Result "1/2"]
[Eco "B92"]
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be2 b5 7.Bf3 e5 8.Nb3 Bb7 9.a3 Nbd7 10.0-0 Qc7 11.Be3 Nb6 12.Na5 Nc4 13.Nxc4 Qxc4 14.Qd3 Qxd3 15.cxd3 Be7 16.Rac1 Rc8 17.d4 0-0 18.d5 g6 19.Be2 Nd7 20.Bh6 Rfd8 21.Bg4 Rb8 22.Bxd7 Rxd7 23.Be3 Bd8 24.b4 Rc7 25.Na2 Rbc8 26.Rxc7 Bxc7 27.Rc1 f5 28.f3 Kf7 29.Kf1 Ke7 30.Ke2 Kd7 31.g4 f4 32.Bf2 Ra8 33.Nc3 Bd8 34.h4 Rc8 35.Kd2 Rc4 36.Na2 Rxc1 37.Kxc1 h5 38.g5 Kc7 39.Kd2 Bc8 40.Ke2 Kb7 1/2

Note that Opocensky, contrary to Boleslavsky's 5...Nc6, used the move order 5...a6, which was later popularized by Najdorf.

Feb-07-09  WhiteRook48: these players of the day keep on making me feel dumb
Feb-08-09  AnalyzeThis: Yes, for a time, Opocensky was mentioned in the same sentence as Najdorf for the now well known setup involving ...e5.

  Penguincw: R.I.P. Karel Opocensky.
May-18-12  minasina: There reads anachronism in the bio. There wasn't any Czech Republic before 1993. There were Czechoslovakia, and apparently he was many times Czechoslovakian Chess Champion?
Sep-08-12  Karpova: Opocensky won the Prague City Championship in 1934 with 8.0/9 ahead of Karjakin with 7.0, Zitta with 6.5, Rejdal with 6.0 and Pelikan with 5.5, etc.

From page 253 of the 1934 'Neue Wiener Schachzeitung'

Sep-08-12  Karpova: The 11th Kautsky Memorial in Prague in 1934:

1. Opocensky 11.0
2. Dr. Treybal 9.5
3. Kopecek 8.5
4. Karjakin 8.0

5-6. Chodera 7.5
5-6. Dobias 7.5
7-8. Zitta 6.5
7-8. Flohr (Salomon's brother) 6.5
9. F. Treybal 6.0
10. Dr. Skalicka 5.5
11-12. Koska 4.0
11-12. Dietze 4.0
13-14. Rosenbaum 3.5
13-14. Petkiewitsch 3.5

From page 375 of the 1934 'Neue Wiener Schachzeitung'

Dec-13-13  Karpova: <Der Ustredni jednota ceskoslovenskysch sachistu v Praze ersucht uns um Veröffentlichung nachstehender Zeilen: Laut Beschluss des "Verbandes der tschechoslowakischen Schachspieler" erkennt dieser Meister Opocensky nicht als seinen offiziellen Vertreter an und wurde Herr Opocensky vom Oesterreichischen Schachverbande privat eingeladen.> (The ... requests us to publish the following lines: By virtue of decision of the "Association of Czechoslovakian Chessplayers", Master Opocensky is not being recognized as their official representative and so Mr. Opocensky was invited privately by the Austrian Chess Federation.)
