The article on Przepiorka also states that he was presumably killed in April 1940, not 1941 as it says in his bio above.

It took place from Dec-26 to Dec-31 1926. The Munich Chess Club celebrated its 90th birthday.

Final standings:

1. Przepiorka 4.5
2. Bogoljubov 3.5
3. Spielmann 3.0
4. Saemisch 2.5
5. Gebhard 1.0
6. Schmitt 0.5

Przepiorka drew with Bogoljubov and won 400 Mark (Bogoljubov 300, Spielmann 200 and Saemisch 100).

Polish Championship in Warsaw, April 19 to May 2, 1926.

Qualification events were held in various cities to choose the 18 participants: Warsaw (<Blass> and <Frydman>, ahead of <Lowcki>), Lemberg (<Friedmann>, as neither Morawski, Popiel, Wojcik nor Wrobel were available), Krakow (<Chwojnik> via "Nowy Dziennik" and <Konczynski> via Master tournament), Lodz (<Kolski> and <Appel>, Bialystok (<Regiedzinski>) and Poznan (<Lubinski>).

Final standings ("Winner Group" places 1-10):

I expect the source for this was <The Oxford Companion to Chess>. Przepiorka's presence on the Palmiry execution lists was only discovered a few years ago.

But the <Companion> does relate a couple of pieces of interesting information we can probably have faith in:

<An amateur, on one occasion requesting a medal instead of prize money...> His Wikipedia entry confirms that Przepiorka was a person of independent means.

<Also a patriot, he sold his house to finance the Polish team's trip to the Buenos Olympiad 1939.>

Relevant passages from the § 130:

<(3) Mit Freiheitsstrafe bis zu fünf Jahren oder mit Geldstrafe wird bestraft, wer eine unter der Herrschaft des Nationalsozialismus begangene Handlung der in § 6 Abs. 1 des Völkerstrafgesetzbuches bezeichneten Art in einer Weise, die geeignet ist, den öffentlichen Frieden zu stören, öffentlich oder in einer Versammlung billigt, leugnet oder verharmlost.

(4) Mit Freiheitsstrafe bis zu drei Jahren oder mit Geldstrafe wird bestraft, wer öffentlich oder in einer Versammlung den öffentlichen Frieden in einer die Würde der Opfer verletzenden Weise dadurch stört, dass er die nationalsozialistische Gewalt- und Willkürherrschaft billigt, verherrlicht oder rechtfertigt. >

My translation (which is quite bad, but hey, try to translate those long sentences well!):

< (3.) With an imprisonment up to five years or a monetary fine is punished, who approves of, denies or plays down a deed, done by the Nazis, which is of a kind of a deed mentioned in the <§6 of the Völkerstrafgesetzbuch>, in a kind which could disturb public peace in a way it could injure the dignity of the victims.

(4.) With an imprisonment up to 3 years or a monetary fine is punished who disturbs the public peace and the dignity of the victims by approving of, glorifying or justifying the National Socialist tyranny and arbitrary domination>.

§6 Genocide

1. Kills a member of the group

3. Puts the group under life conditions which are capable of a complete or partial physical destruction
