NOTES:

1. You may open the Bookmarks tab to the left, and scroll and select an ECO code to jump to that ECO code.

2. You also may search this document for a word or name using the Find command. Instead, you may use a particular ECO code (A57). Another way to search would be for a particular move; e.g., 2.Be3, 5.Bxf8, etc. (do not put a space between the number and the period/s or between the period/s and move notation). For searching for a proper name with a special character Réti, Tübingen, etc.), use the proper name without the special character.

3. PGN game collection files for ECO A00-A99 for studying can be obtained from the following webaddress at the Bookup website; however, Bookup was replaced with a new Chess Openings Software in 2007. The link for Chess Openings Software on that page is to the old Bookup software, so you should not use that link. I am unsure how long the webpage and files will be available. Also, the pgn files may contain more variations than listed herein. PGN Game Collections Downloads for A00-A99 www.bookuppro.com/ecopgn/a.html

2. You also may search this document for a word or name using the Find command. Instead, you may use a particular ECO code (B57). Another way to search would be for a particular move; e.g., 2.Be3, 5.Bxf8, etc. (do not put a space between the number and the period/s or between the period/s and move notation). For searching for a proper name with a special character Réti, Tübingen, etc.), use the proper name without the special character.

NOTES:


2. You also may search this document for a word or name using the Find command. Instead, you may use a particular ECO code (C57). Another way to search would be for a particular move; e.g., 2.Be3, 5.Bxf8, etc. (do not put a space between the number and the period/s or between the period/s and move notation). For searching for a proper name with a special character Réti, Tübingen, etc.), use the proper name without the special character.

The link for Chess Openings Software on that page is to the old Bookup software, so you should not use that link. I am unsure how long the webpage and files will be available.

Another way to search would be for a particular move; e.g., 2.Be3, 5.Bxf8, etc. (do not put a space between the number and the period/s or between the period/s and move notation). For searching for a proper name with a special character Réti, Tübingen, etc.), use the proper name without the special character.

2. You also may search this document for a word or name using the Find command. Instead, you may use a particular ECO code (E57). Another way to search would be for a particular move; e.g., 2.Be3, 5.Bxf8, etc. (do not put a space between the number and the period/s or between the period/s and move notation). For searching for a proper name with a special character Réti, Tübingen, etc.), use the proper name without the special character.
