What is the recommended time for single-elimination quarterfinal or semifinal matches?

The recommended time for single-elimination quarterfinal or semifinal matches is 90 minutes. This duration is established to ensure that players have ample time to complete their matches without feeling rushed, as these rounds can involve longer and more complex games due to the increased stakes compared to earlier rounds. Each match could potentially extend due to intricate strategies and plays, so designers of the tournament rules aim to provide a reasonable time frame that accommodates the competitive nature of single-elimination formats while also maintaining a structured event schedule.

This time limit helps to keep the tournament running smoothly, as it balances the need for fair play and the urgency to progress to the next rounds. In single-elimination formats, where players are vying for advancement with fewer opportunities to recover from losses, having 90 minutes allows for full games to be played without undue time constraints.
