This trope only applies if one suitor challenges at least one other suitor to the contest. If the contest is imposed by a third party, such as by the maiden's father or by the maiden herself, then the example belongs in Engagement Challenge.
Despite the name, this trope applies equally to both males competing for the affections of a female and females competing for the affections of a male. It also applies to same-sex relationships. The trope name was chosen only because it's the most well known version of the trope.
- The trailers for the (as of early April 2017) about-to-be-released 21th Detective Conan movie, Crimson love letters, state that a gender flipped version of the trope will take place.

This coincides with Momiji being Heiji's Self-Proclaimed Love Interest, confronting both Heiji and Kazuha on their potential love triangle, and Kazuha deciding to challenge Momiji both in love and karuta...

- Extreme Prejudice. Texas Ranger Jack Benteen and former friend-turned drug kingpin Cash Bailey duel for Sarita, even though her own response to this is You're Insane!. Really though these two have been heading for a gunfight one way or another, so they may as well do it for the woman they love.

Unfortunately, it turns out Mevanwi is a Manipulative Bitch and Guenievre isn't exactly living the dream either, so the exchange is later cancelled.

Paris thinks he's got the goods because of his title (a Prince no less) but the moment Juliet makes eye contact with Romeo at her father's ball, she's pretty much made up her 13 year old mind. And Paris never finds out. When Romeo ends up killing Paris outside Juliet's family's mausoleum, only then does Romeo acknowledge any sort of rivalry.

- This happened in the backstory of Cullyn of Cerrmor in the Deverry novels. The only thing that kept him from being hung over killing his opponent was the fact that witnesses stated that the other guy started the fight. He did end up exiled from his home city and forced to become a mercenary, with the woman in question choosing to follow him and ending up a barmaid in the only tavern in a nothing village in the middle of nowhere. Cullyn would later swear an oath to never again kill over a woman - it doesn't do any good for any of the involved parties, a decision that allows him to break free of a four-hundred year old chain of wyrd.

- There's also a gender-swapped version, with a guy seeing his girlfriend at the Copper Coronet back rooms while his wife is out looking for him in the main area. If you tell her where he is, she'll confront them, whereupon the girlfriend pulls a knife and they fight. If the girlfriend wins, she'll drag him off to be married properly, whereas if the wife wins, he'll be enamored with her for it and return home with her.
