I know he wrote a few books, including one on the 'Bremer System' (English with early White finachetto).

In those days, one became a Master in Germany by winning a Hauptturnier. Carls came close with a second place finish at Hamburg 1910 (Rotlewi won), then broke through with a victory at Cologne 1911.

After this he was qualified to play in the master section of the German Chess Congress, which was equivalent to a strong international tournament. His usual finish was around 15th in an 18-20 player field, but he did score some notable individual victories, such as defeating both Spielmann and Tarrasch at Breslau, 1912.

After the war, the German congresses were generally weaker and Carls' results improved: 5th-7th at Hamburg 1921, 2nd at Oyenhaousen 1922. His major international tournament came at Baden-Baden 1925, where he finished his usual 15th in a strong 21-player field.

He had solid results playing 3rd board for Germany in the Olympiads at London 1927 (63.3%) and Hamburg 1930 (67.9%). He also competed in the Amateur Championship at Hague 1928, finishing 7th.

After this, he confined his action mostly to local tournaments for the next decade. However, he did play in the first two German Championships, finishing 4th at Bad Pyrmont 1933 (Bogoljubow 1st) and winning the title at Aachen in 1934 (though it must be said it was a very weak field). Also, in the so-called "Extra Olympiad" at Munich 1936, he played fourth board for Germany and recorded his usual solid result with 58.8%.

He was jerked back into activity for some of the Nazi-sponsored tournaments during World War II, finishing 7th-10th at Krakow 1941, 1st at Rostock 1942 (ahead of Klaus Junge, but no other important players), then withdrawing after 8 rounds at Prague, 1943. After that, the only event I can find is the German Championship at Bad Pyrmont 1949, where finished well down in the crosstable with 4.5/12.

He was not very successful in match play, losing to Bernstein (+2 -6 =2), Eljaschoff (+1 -3 =0), E. Cohn (+1 -6 =1), and Suechting (+1 -2 =0). He did win several matches from fellow Bremen player Antze in the 1930s, but these may not have been totally serious affairs.

The Main tournament B consisted of 3 groups (9 players in groups I and II, 8 in group III). Carls played in Group I and shared 1st place with Arpad Bauer - both had 6.0 points (Carls scored +6 -2 =0, Bauer +5 =2 -1).

Both were allowed into the <Siegergruppe>, but while Bauer finished last (+0 -6 =2), Carls won 1st prize (+6 -0 =2). Carls got 250 <Mark> and the honorary cup of Cologne. Furthermore, he became German Champion.

<Das Turnier zu Breslau hat nur einen bisher unbekannten deutschen Meister an die Oeffentlichkeit gebracht, Carls aus Hamburg. Die übrigen deutschen Teilnehmer, Cohn, Mieses, Dr. Tarrasch und Teichmann, sind längst erprobt. An den Leistungen des neuen Kämpen kann man sich eine ungefähre Vorstellung von der Stärke der jungen Schachgeneration machen. Danach zu urteilen verspricht sie nicht Genies zu produzieren, hat aber Sinn für Kraft und packt das Erreichbare mit fester Hand. Carls zeigte sich im besten Lichte gegen Spielmann und Dr. Tarrasch.>

(The Breslau tournament made only one so far unknown German master public, Carls of Hamburg. The rest of the German participants, Cohn, Mieses, Dr. Tarrasch and Teichmann, are time-tested. From the efforts of the new comptetitor, one can gather an approximate assessment of the strength of the new chess generation. Judging by that, she doesn't promise to produce geniuses, but has a sense for force and grabs the accessible with a firm hand. Carls was at his best against Spielmann and Dr. Tarrasch.)

... Auf den ersten Blick ist die Entstehung der Bremer Partie schnell erzählt, zumal sie Carls selbst berichtet: spätestens mit dem Turnier in Ostende 1906 wird dem Amateur deutlich, dass seine Eröffnungen auf dem professionellen Niveau nicht ausreichen. Aus Zeitmangel sucht er sich zu spezialisieren, und zwar derart, dass seine Gegner nicht ausweichen können. Da seine ersten Versuche mit 1.g3 dem Schwarzen ein zu starkes Zentrum erlauben, schaltet er den Zug 1.c4 vor.

Am 18. Juli 1909 in der ersten Runde des Meisterturniers des 13. Niederelbischen Schach-kongresses in Harburg ist es soweit: Carls eröffnet gegen Dimer mit 1.c4 und 2.g3 – es ist die Geburtsstunde der Bremer Partie...
