Position Search in the Forward Chess library

ChessChess engineAnalysisSoftware Development
Searching for positions in books you own and do not own is now possible

Forward Chess is my favourite chess e-book reader!
(I am not affiliated with Forward Chess and do not get sponsored. I am just sharing my excitement about this new tool as a user.)

If you are familiar with Forward Chess, please skip the 'Introduction' and read the 'Search for Position' paragraph.

Introduction

Forward Chess offers more than 1,100 books from all major publishers in digital form.
I have about 25 books and read them on my iPad, iPhone and laptop.

My Forward Chess Library

Forward Chess is like Kindle for chess. Like on Kindle, you can highlight text, make bookmarks, add notes, etc.
But as you can see in the picture below. Forward Chess also gives you a board with an engine to play through the moves and try your own variations.

Some of the main advantages of Forward Chess are:

  • Portability: You always have your complete chess library with you
  • Efficiency: You do not have to spend time setting up a position
  • Cheaper: Forward Chess e-books are often cheaper than physical books
  • Instant Fullfillment: If you buy a book, you can immediately start reading it and do not have to wait for shipping
  • Strong engine: Stockfish 16, post NNUE (Chessable: Stockfish 14 = pre NNUE)
  • Extensive library (more than 1,100 books) with all major publishers represented

Search for Position

Forward Chess has introduced the possibility to search for a position in the complete Forward Chess library.
It not only searches in the main lines but also in all the subvariations. This contrasts with Chessable, where the search for positions is limited to trainable variations and subvariations are not included in the search.

If you own the book on Forward Chess, you can get to the relevant position in the book with one click.
If you do you own the book, you get a 'snippet' from the book showing the position and commentary in the book.
These 'snippets' are little pearls: sometimes enough as a second opinion, and sometimes you want more, and you buy the book.
In Chessable, if you do not own a course, you will be shown the course for buying, but no content related to the position itself.

If you own the book, you can go to the relevant position with one click.

For me, this new functionality is a game-changer.

Some use cases:

  • When you watch a broadcast, you can look up the theory in the Forward Chess library with one click.
  • In your game review, you can look up your theory with one click and subsequently define spaced repetition for improvement with one click.
  • When you study on Chessable, you can search for a position in Forward Chess to get a different perspective.

What is unique:

  • Search in the complete library of Forward Chess
  • Search in main lines and all subvariations
  • High-quality 'snippets' for books you do not own
  • Ability to go with one click to the exact position in the book for books you own
  • Ability to define spaced repetition for any position in the book
