1337chess PRO Anniversary!!

Today is exactly a year since I've began working continuously daily on 1337chess PLUS or PRO opening book series. Engine chess and making opening books has been a hobby of mine since 2005 and this is the most tedious and the longest that has been developed so far.

Years of CPU time has been spent, over a thousand book versions and a couple of terabytes worth of opening books tested. Thanks for all your support, we hope to continue making better opening books in the future. :-)

1337chess FREE Polyglot

1337chess FREE Polyglot now available:
Download:
http://depositfiles.com/files/5uoz67mwk
or
http://www.mediafire.com/?mscbn3bjhcn93z5

A highly experimental book mine which you can use in any GUI besides using Aquarium Adapter. Included is a specialized Polyglot UCI adapter, which is very easy to use, simply copy your engine of choice in the polyglot directory and put the folder directory and the engine name on the polyglot.ini and install the polyglot.exe on any GUI you want like a normal engine. It should play instantly on opening.

I recommend disabling any GUI books to purely use the polyglot book, that is if you use fritz you can create a blank ctg or make sure it loaded no book. Absolutely no other settings required.

Regarding book strength, I don't guarantee it but it should be decent enough. If you want a heavily tuned book and guaranteed strength, try the latest version of 1337chess PLUS it is the current top leading book. Although currently in ctg you can also use it on any GUI using Aquarium Adapter.

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 =)

This is after version of my book that participate in SCCT book tourney.

It is currently top 5 out of 53 books on that tour, which is guess is modest enough for casual engine play.

Here is other older books I made. Although already some are outdated, you may find it useful to test your own repertoire or as a reference:

New Book - 1337lite p1.ctg

After months of being dormant, I will finally release one of my books.

Here is 1337lite p1.ctg book: download link

First of all thanks to all my book testers for sending me their games and analysis. Nothing too special in style, I just follow mainlines and try to see up to where I can push mainline opening theory. It's narrow but I think it is modestly solid enough.

If you like an extended version you can be one of my tester and I will provide you with more frequent update but you must provide games played by the book of course.
- games must be engine games or engine assisted games
- Your Evals of games must be turned on (if on pure engine)
- engine games can be played on local machine or internet games

or you can donate any amount and I'll instantly give the latest version to you. We can also trade games for book or games for games if you like.

Precise Engine Testing - A new method of engine testing

Engine testing in a common way is rather simple, the common method is to set the two candidate engines, load a balance opening db such as nunn test suite or a balanced opening book with varied ECOs and set the match at tournament or blitz time control. This is done by popular engine testing sites such as CEGT or CCRL. The problem is with this of course is their accuracy and the time it takes for the tournament. It takes almost a year to test an engine and still has +/-10 elo error margin.

The new method takes a day or less, and has ~0.00 error margin, yes we will tackle the world of Micro-Elo :-)

War II.ctg

I introduce a new book War II.ctg, well it's rather a month old I was too busy and forgot to release it. New style again, like tuned 1.d4 as white. I made it simultaneously with 3 books including War I about a month ago. This is totally different book and not a continuation of War I, if you still like 1.b3 and 1.e4 e5 etc. you may use War I. It ranked number 5 on sedat chess rating list, it's only weakness maybe some of its black lines so watch out. Download

For those who donated thanks again. I will try to really send you something special one of these days :-)
If you like private talk, suggestions and sending games email me at mw2q2q@yahoo.com

Thanks.

War I.ctg

I introduce new book again, War I.ctg. With new style and of course manually tuned. Settings are the same with conquest and pfredchen books series.

If you like it you can donate, and might get future books earlier than public. For those who donated stay tuned =)

Building a Cluster

A cluster computer is basically many computers merged into one usually to perform a single task or process. A typical 'normal' cluster of course are blades, data centers and rackmounts but they will also cost more. Multiple desktops can also be used as a cluster, which is what I will be discussing in this post. A desktop cluster is of course cheaper.

The cluster I will be showing you today is of course build for small budget and for space saving. So we will be using Micro Atx boards and laptop hard drives so it can fit on our custom server rack which is a file cabinet.
