final score 142/200

Naum was ahead at half way vs Zappa Mexico (commercial), but at the end Zappa came back and won the match 11/20

Fruit 2.3.3J did very well even if it lost. This is probably a stronger version than 2.3.1 at least vs others engine

It would be interesting to test Glaurung on 8 cpu , because for this
test , I was still running Glaurung with 4 CPU .I notice with the
Glaurung benchmark that Glaurung 8 cpu is around X 1.5 ( or 50% )
faster than on 4 CPU for the Kn/s


I was surprise to see Naum SMP 8T won 15-5 vs Rybka 1.0 (The best Free UCI engine for the last 2 years )

Free Chess engine did what they could but at the end Naum SMP was simply too strong...even for strelka

On CEGT and CCRL rating , the difference between Naum 2.2 Single
CPU and Naum 4 CPU is more than 100 elo. It is probably over 120 elo
between the version 1 cpu and 8 CPU !!!

This version 2.3.3 J is well tuned vs Free Rybka and Toga ... The 2 top free UCI engine the last 2 years

It  managed to beat all free Top UCI engine (  Rybka, Toga, Pharaon ,Naum, Spike ,Glaurung...) in a 20 games match except Strelka.

It draw vs Fruit 2.3.1 .

It has a lot of difficulties vs Strelka 1.8 (a lot of controversy around Strelka ,illegal  Clone or not?I don't know & I m not the one to decide)

It was not a surprise to see Fruit lost againstcommercial Zappa Mexico 8 CPU

I m running some  test for  Fruit beta... More version will be test ...

This one did well versus strong Free UCI engine

Results:

Zappa Mexico is Very impressive on 8 CPU (just look at the match RybkaSMP vs Zappa Mexico!!)

That s why I decide to test it on my 2Xeon 5365 (8CPU 3ghz) 

Zappa was able to score 74.5 % vs 10 top Free uci Engine!!! (and this is just The 32 bits version)

It managed to score positive record vs all opponent (only Strelka draw it, I was alittle bit surprise )

Toga,Strelka and Glaurung SMP (it was on 4 CPU) did very well vs Zappa Mexico (A top 2 commercial engine )

This is the first Time I saw a Top Commercial engine other than Rybka that could beat easily the top 10 free UCI engine ...

It was a big surprise to see Zappa Mexico score 80 % vs Free Rybka 1.0 (A top 3 free engine , maybe the best free engine). It gave a chess lesson to others free UCI engine (95 % vs Pharaon !!! 80 % vs Fruit 2.3.1, 80% vs Spike 1.2 ...)
