Dear Chess Friends,


First of all I'd like to point out,
I respect all engine testers, book authors, engine authors...!
And I am not against nobody, my main goal is for CompterChess's progress!!

Note also that,
Anybody is free and he/she can test any engine with any opening, which he/she likes...no problem!

But however, I think it's time to change our views...
In other words: it's for a new revolution in engine testing!

Because as far as I noticed, unfortunately many testers suffer...
They are wasting their valuable time with many clones, derivatives, weak openings etc..

Unfortunately, still we have no any major stable and proper rules,
Even chess engine programmers (each other) have different views about origins...

So we are engine testers,
We need to know: which chess engines are 100% original work ??
And which original chess engine should be as participants ?
Is there a such chess engine, which is based 100% on own original ideas ??

According to my chess engine experience:
- There is no such thing...correct me please if I am wrong...
Of course, there are such engines which belong to the most original ones

That's why... I can't see any other right way, exception my current used rules

And I kindly recommend to testers (who have doubt about origins) to use SCCT rules!!

So here is my recommended rule (in case of 55% similarity and above),

We need to:
- Use the sim tool by great Don Dailey
- Calculate sim test with time: 100 ms scale: 1.0
- Check the both engine Elo points
- Ask for a help by neutral engine experts views
- Test only those ones which are released before
- Test only those engines which are 100 Elo stronger
etc...

Otherwise,
Our tournaments, especially I can say for Top 20:
-Almost all top participants will be based mainly on Rybkanians, Stockfishians etc..!
-And allowing only Naum, Ctritter, Fire etc...will be injustice over rest derivative authors

Once more I'd like to point out that,
SCCT's current rule: 55% +100 Elo is not perfect,
But probably the best tournament rule comparing with other available rating lists !!

Just an example, see below please (Heron seems to be very close to Stockfish):

sim version 3
------ Heron impossible 231113 X64 Normal mode (time: 100 ms scale: 1.0) ------
60.86 Stockfish 2.1 JA 64bit (time: 100 ms scale: 1.0)
60.39 Stockfish 2.1 JA 64bit (time: 50 ms scale: 1.0)
58.27 Stockfish 140614 64 SSE4.2 (time: 100 ms scale: 1.0)
58.06 Stockfish 1.7.1 JA (time: 100 ms scale: 1.0)
57.88 Stockfish 1.7 JA 64bit (time: 100 ms scale: 1.0)
55.85 Stockfish 1.5 JA 64bit (time: 100 ms scale: 1.0)
55.30 Protector 1.7.0 (time: 100 ms scale: 1.0)

Just I'd like to add this too, in my opinion:
- 55% similarity and above, plus almost same Elo points (based on original program) is a clone or derivative engine !

So... with our new rules we will request just +100 Elo, not much...

In this way...
We will give chance to all engine programers, which are based mainly on own strong ideas!

Some engine programmers proved that (cleaning other codes, made BIG Elo improvements...)
And it's your turn...why not you ?)

Note also, my suggestion is not a DESTINY !)
It's just matter of choice...

Don't forget this too please,
ComputerChess is our hobby...so we should not take too seriously all the things)!

And last,
I hope my current posting will be useful (especially for the new generation)!!
