Can You Solve Our 2021 Holiday Puzzler?
Your favorite annual chess quiz tradition is back for the 2021 holidays.
Enjoy this year's quiz, and see if you can win one of our prizes for a top score.
[Jan. 5, 2022 update: click here to see the correct answers and winners.]
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 Tuesday, January 4, 2022, 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 or titles. For chess moves, use simple algebraic notation without a move number (e.g. Nf3). For fractions, use the most simplified (e.g. 1/2).
- 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
- 11th-20th place: One year of Chess.com Gold membership
