Btw,i have updated the conditions with more details:

For Better Engine Performance
•MP Engines are played between each other using 6 physical cores
•Perfect 2012b’s opening lines are frequently tuned/optimized
•Adapters (Polyglot,Wb2Uci…) are not planning to be used
•Multiply Matches (running several GUIs on same PC) are not allowed
•LIVE Broadcasting Tools (Publish Tournament on WEB) are not allowed
•During Matches:No any external software is running in the background
•It’s not installed any programs to tray in the Taskbar (Startup)
•The SCCT Tournament Computers are daily ShutDown
•Internet is disabled as protecting from any kind of threads
•No clicking with mouse,no typing…(when the tourney is active)

SCCT Rating’s Disadvantages
•Chess Engines are played with Ponder OFF (NON-Auto232 mode)
•Some opening lines of Perfect 2012b book still needs optimization
•Blitz time control has been used (not many high-quality games)
•For more reliable rating, more engines and games are needed
•No LIVE Broadcasting (external PC and webcam is missing)

SCCT Rating’s Advantages
•Engines are played with same time control on latest fast machines
•64 bit / SSE Engine versions have been played,using 6 physical cores
•It’s true that Ponder ON is better for Chess Engines,but note also that:
-Ponder OFF 6 core is approx. 140 Elo stronger than Ponder ON 1 core
•During matches:no external software is running (e.g LIVE tools or several GUIs…)
•As far as possible, the strongest modern openings are preferred and used

Time Control
•All games are played with same time control: 3 Minutes/Game + 2 Seconds/Move
*One of the most preferable blitz time controls, used in latest Chess Championships
•The overall time duration game length:equals to average 11 minutes per game
•Personally I’m not a big fan testing the engines with fast time controls
•Blitz games are less important and the results cannot be taken as very seriously
•But however, blitz is the most used and played time control in chess
•The main reason i use this blitz time control for the current rating is very simple:
-As a single tester,I have no enough free cpu time to create a reliable slow rating
•Plus blitz chess offers more possibilities to test many different engine versions

New Engine Update:
Ivanhoe B46fE.02

More games are needed for better conclusion

But however,Ivanhoe B46fE.02 x64 seems to be a very strong compile

As we see, the current Ivanhoe B46fE.02 results are impressive so far

My Congratulations to Ivanhoe team and Izak Pretorius!

More Ivanhoe B46fE.02 x64 6c games are added

The current Ivanhoe version's start was impressive (up to 200 games),but unfortunately was not so lucky in the last 250 games

But however,as a freeware engine-very good results !

Hi Sedat,

Actually I believe there is "a whole basket" of best Ivanhoes, where you can find
Ivanhoe B46fE.02
Ivanhoe B46fC
and perhaps George's favorite, Ivanhoe B46e
... and others (Ivanhoe 46h)

Since nobody seems to be working in depth with the Ivanhoes sources, progress is very small.

Dear Ernest,

Agreed with you...

But anyway, i think mostly of the new Ivanhoe releases are becoming slightly (approx.+5 Elo) stronger than previous older Ivanhoe versions

For example, approx.5 Elo improvement is really a lot for each release (because we see oftenly new Ivanhoe versions )

I tested many Ivanhoe versions (the below standing is based on SCCT Auto232 Rating)

As we see,Ivanhoe 46hm performed slightly weaker than Rybka and Stockfish

But in the current SCCT Rating, Ivanhoe B46fE 02 x64 performed stronger than Rybka and Stockfish

In other words, it seems Ivanhoe B46fE 02 x64 is one of the strongest ones,but after more games it will be more clear...

One thing more,

In my Ivanhoe 46h's testings,I was not satisfied by its performance

Not sure 100% what can be the reason,but i noticed indeed strange standings:
http://www.sedatcanbaz.com/chess/scct-sse-no-sse/

But however, I think the 'Multiple Matches' (using several GUIs) is the the main reason of those strange results
Another factor of those strange results can be:Engines are played without books
Note also that Critter has many games forfeits on time too (i never noticed same thing before by Critter)
And i dont believe the current standings will be changed a lot (if there will be more games),due to the engines are played without books

For example,i am quite happy with the current SCCT conditions
And unfortunately there is only one engine:Fruit 090705 (tested under Fritz/ShredderGUIs),which has several games lost no time

Sedat

Hi Sedat,

Actually I believe there is "a whole basket" of best Ivanhoes, where you can find
Ivanhoe B46fE.02
Ivanhoe B46fC
and perhaps George's favorite, Ivanhoe B46e
... and others (Ivanhoe 46h)

Since nobody seems to be working in depth with the Ivanhoes sources, progress is very small.

If I am alive and well this should change before the end of 2012.
I am working on a "compile" and planning for 50+ elo not 5.
I will be working in depth this time.

Best Regards
Izak

Dea Izak,

You compiles a truly very strong!Great job and keep up the good work!

And it sounds good....in case of +50 Elo Ivanhoe improvement,that mean we will see a serious opponent against Houdini


Best,
Sedat

Izak, I also think you are doing a great job!
