Cloned Books

I also put "watermark" positions in all of my books to track them on public domain, quite amazing to see who copies it. Here's one:



EPD:  7k/8/8/BNBRrnbn/NBNRrbnb/8/8/K7 w - - 0 1

Chances of having this position and the combo of moves following it is much slimmer than winning a lottery. Unless you just copied the book ;) Obviously V4VENDETTA is a variation of 1337chess 2012 free book that I released.

If you want the Original and the Best only get it from here =)

One of the best free openings book out there, probably can match your best private or commercial books. But it is our weakest, we do hope somebody will beat it by several elo points real fast =)

For the latest development,
try out new 1337chess PLUS Version 2. Much more openings and many elo points stronger!

Enjoy!

1337chess 2012

I haven't release a book for sometime now, but you'll probably find this book a quite decent release.
It's your traditional tournament openings book, lines are designed to go deep. If you play correspondence chess you might find some new ideas too.
