New 1337chess PLUS v3 Released!

New 1337chess PLUS v3 now available. Stronger than ever, here is a quick 3min test versus today's popular books using houdini 3:

 

Average Success Rate in this test is 70% or around 150 elos stronger than these books. At the very least likelihood of superiority is guaranteed.
1337chess books now also tuned much more frequently, you can now get updates twice a week.  New book pops up, no problem we'll destroy it in a few days ;) See here for more info.

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!
