Public League tour is completed and this is not as joke..why I say

Like this..because in a very short time I managed to organize it..!

No doubt that there was a BIG battle...here are the final standings:

The winner of Public tour: 1337Chess, 2nd rank belongs to DON

The 3rd rank belongs to two books: Chucaro 4 and Time-Lord...

Congrats and many thanks to all, for your interest and hard work!

Meanwhile, the overall draw ratio is 90% frankly, I expected more...

It seems, my created Raubfish SC settings are played some role

And very soon (probably today or tomorrow) I'll start Private tour

If anyone interested, the participants of Private League: Players

Breaking News - 20.06.2022:

Well, as I promised, the current championship is already started..!

First of all, Public League will be played... sure later, I plan to run

Private League as well....Note that the total opening books are 48

To be more clear, 21 Public books, where the Private books are 27

In other words, a lot of hard work is waiting me in the next days.. !)

However it's all right because I love chess and sounds perfectly ok..

As players, I picked only new versions which never played in SCCT

And sorry that I did not include all books...due to no much free time..

Note also that Both Leagues are expecting to be ended in 7-10 days

For anyone interested, Public League books can be viewed: Players

Ok...that's all for right now and I wish everyone all the best of luck!

Latest Update: 05.06.2022

Dear Chess Friends,

As usual, I'm pleased to announce that,

Another new Championship is coming soon..

1st of all,

Tournament Start Date is expecting to be on 20.06.2022

Book registrations will be acceptable on 10 - 19.06.2022

Size limit for CTG: 400 MB / BIN: 200 MB (coımpressed)

Any book will be played minimum 400 games (per player)

Tournament's duration is not so clear...it will depend on my

Free time, that's why in case of interest... please don't be

Too late...thank you in advance )

Important Note (For Frequent Book Authors),

There is a special 'BONUS' for the current new BOOK/ NN Tours:

The frequent Authors can submit books up to 5 GB (coımpressed)

In case...it will be my BIG pleasure to test these GIANTS as well

Plus I can accept two books from same Author, e.g one Private,

Where the 2nd opening book have to be simply as Public one...

To be more clear,,

The planning tourneys will be different than all, just a few details:

All books will be played by same engine: Raubfisch X48c3 NNUE

Note: A modified RaubfishX48c3 engine will be played, the reason:

Simply to increase the wins, otherwise wouldn't be too much boring?

And according to latest strength testings, my modified Raubfish ver.

Performed slightly stronger than default...it seems more aggressive..

And no doubt that too Raubfish belongs to super strong NN engines

But the most important thing is that: it's not so much Drawish, I mean

Raubfish X48c3 NN is not like mostly other Stockfish based ones e.g:

After 326 games, Raubfish (playing itself) produced 87% draws, yes

For 3750 Elo NN engine, these stats are not high (Blitz, Ponder ON...)

Btw, forget everything even as NON-NN, (via short strong openings):

Many SF based ones produce close to 90% draws, where Raubfish

Even as NN (via Evalfile) produced less than 90%..that means a lot!

I assıme for your side too...not so clear?) well, then simply I will say

Almost all (e.g close to 3750 Elo) produced over than 95% draws...

And to be honest, I can't see any other NN engine to be so strong...

And in same time to produce such low draw-ratio, in short just great!

Sure these draw values are produced via Balsa, Perfect books, but

Via deep strong books, probably the overall draws would be higher...

Not sure exactly...the time will tell...btw, nowadays I'm too busy...but

Later I'll publish all Raubfish's results + including settings as well

Note also that, (sure for more fair conditions)

I hope to organize/run two separate tournaments:

- Private League = only Private books will be played each other

- Public League = only Public (available) will be played each other

- BIN vs CTG books will be played as Book Learning OFF

In other words,

Another new testing method... and really not so easy as it looks...

Especially Private League will be as one of hardest that ever seen!

Because in these tours, there will be no matches: Private vs Public...

Note also that there will be two titles: Private / Public Champion

Just I'd like to add, this time the planning conditions are better e.g

Stronger NNUE engine, Blitz time control: 2m+1s, Ponder ON etc.

That means also, less blunder moves, sure better quality games...

In same time, I expect to see many wins, that means more fun!

What we can need more...?)

Meanwhile (for anyone missed, interested...),

Raubfish series are not only as one of strongest in Game-Play, but

They are just great in Analyzing-mode too: Results / OTS4 / OTS3

Ok..that's all for now...for more details, please feel free: Contact

And be ready for the 'real' Arena, because it's worth to be

Participated into one of the hardest and exciting events !)

Best,

Sedat
