Why did Arthur Schopenhauer schedule his University of Berlin lectures at the same time as Hegel’s?

Arthur Schopenhauer scheduled his lectures at the University of Berlin at the same hour as Georg Wilhelm Friedrich Hegel as a deliberate attempt to challenge him.1

Schopenhauer, who held a deep philosophical opposition to Hegelian idealism, sought to compete directly with Hegel for students. However, this strategy proved unsuccessful, as he could not effectively challenge the popularity of Hegel’s "persistently advancing philosophy," which drew a large and growing audience. Consequently, Schopenhauer held only his first lecture and remained unable to establish a successful teaching career at the university.12
