Rules:

• All ties will be resolved by the earliest received submission, so send in your answers as soon as you know them. But try to be as accurate as possible—it usually takes close to a perfect score to win. 
• Answers will be accepted until 11:59 p.m. (Pacific Time) on Monday, January 4, 2021, or 8:59 (Central European Time) on Tuesday, January 5, 2021, and only a member's first submission will be considered.
• Spelling counts. The quiz is scored automatically by Google Forms, so make sure you spell your responses correctly. For player names, write the first and last name only in that order. Use a capital letter as the first letter of proper nouns. Do not use any accent marks.
• You can use any resources at your disposal to get the answers (engines, web search, comment section, phone-a-friend, etc.).
• Provide your valid Chess.com username and an e-mail for your answer receipts in the form.

Prizes:

• 1st-3rd place: One year of Chess.com Diamond membership
• 4th-10th place: One year of Chess.com Platinum membership
