How did Pushkin's work sometimes cause trouble, and what is an example given in the text?

Challenges Faced by Pushkin:

• Trouble with Authorities: His work was very different from other writers at the time and often got him into trouble with the Tsar and the government.
• Example: His famous play, Boris Godunov, was only published years after he wrote it due to political reasons.

Summary: Pushkin's unconventional writing style led to conflicts with authorities, as exemplified by the delayed publication of his play "Boris Godunov" for political reasons.
