Last Update: 23.04.2022 Dear Chess Friends,

 I am pleased to announce that,Here is another new Book / NNUE Championship!

Just I'd like to point out that,After 25 book players, I've realized the current tourney to be ended...Because, in case...next strong ones expecting to perform minus plusIn Top 5 ...and it seems via Stockfish 15 is hard to get higher points...Sure...there is nothing impossible..but a special tuning is required..!Anyhow, I think that now we have new useful data, which may help...
Some more notes about current competition,All books are played:by NNUE engine (like Book / NNUE I) Where this time I tested the books and suites up to 8 movesBut note that only the ones, which prefer more various openings!Perfect or Balsa suites are not participated, the main reason,As usual I have difficulties to find stronger, as you may know,My target is to become no more Champion, once is enough!Plus I have to be a neutral TD....right ?)
However, for anyone missed, interested:Previous competition (up to 8 moves) can be viewed: CS XLVIBtw, If we check more carefully e.g in case of various openingsPerfect 2020a book seems to be one of with best performances!And the same participated book is still available. Perfect 2020a
On other hand,Actually I've organized many tourneys e.g up to 8 or 12 moves etc.But no free time to publish all standings, but in almost all rankings My created Balsa, Perfect, SCCT books are performed not so bad!That:'s true, since 2009: I stopped working over deep opening lines..That's why no chances my books to overcome vs strong deep onesBut in case of testing various short openings, then no comments...!)
Ok...let's back to our current competition ...)
In short, I was wondering much:What is the influence testing various openings via NNIUE engineAnd let's see which opening books, suites are strongest out there!
Meanwhile, without to not mention this I can not too.
According to some guys..they prefer to say:Balanced, Unbalanced, Drawish etc. openings
Actually the situation is not so complicated as it looksThe openings are divided only into two groups:- Strong openings and Weak openings!

 The Champion: Champ - Congratulations to SCCT Top Book Makers! Note: Champ book is derivative one (created by Me) and still Available In short, exactly the same ver once more managed to be Number One!
