Well of course you are free to believe what you want, but in my case the extensive testing was several thousands of games on 2 x Skulltrails, 5x Quadcores, 3 x dual cores and this data was correlated with other beta testers who also had their own hardware and all data compiled together. The 2 Skulltrails consistently were scoring much much better than on other platforms for R4, so much so that even Vas (who is usually very conservative) mentioned that this is more than just statistical noise. Now if you add to this the fact that R3 also has similar much better results on big hardware (8 core or more) then the common denominator between R3 and R4 is that they both use processes instead of threads. Also if you look at the actual games where R4 (or R3), you will see that when low on time and very few seconds are remaining ... it takes a lot longer for R3 or R4 to play a move than other engines. I believe this is mainly due to lag caused by process synchronization during engine initialization. I could be wrong, but I really can't find another explanation, and have yet to see someone else give me a definitive reason.

I am among the ppl who like to call the things with their real names.
To simplify, I think you are just bluntly lying.
As a matter of fact, if you wrote that this month is October, I would still had to look into the calendar before believing you...

Milos my friend, which ass did you crawl out of this time? Can you please specify where I am "lying" and why? This time please try to avoid your major conspiracy theories.

M Ansari, tester, what is the LOS of +15 =24 -11 match? As long as you do not answer THIS elementary question, you are not a tester, and please do not post here on behalf of a commercial engine. Go to your beloved Rybka forum.

Hey dear Guys,

I can not see why are you attacking Majd Ansari,maybe because he is from Kuveyt ?

And i see nothing wrong in Majd's statement,its quite clear that he is trying just to say that Deep Rybka 4 performs (against IPP family engines) better on fast machines and on slow time controls

About availability of games ? hmm...if i start to check carefully...,i will find many standings where the games are not available for downloading too

Remember that Majd Ansari is well respected member in Computer Chess Community and also he is well-known as a hardware expert too

And last nobody has right to say what he should do,where he should go...

I agree with Sedat. We should attempt to communicate in a way that is friendly and rational. It's both common courtesy and common sense.

Since there are absolutely no facts to support his claims, it's quite clear that his claims are nothing but advertising of the commercial product.
This is directly against the point 4 of the charter:
"Are not flagrant commercial exhortations"
However, for unknown reasons moderators are tolerating this.
I'll repeat M Ansari is the only guy on this forum that is constantly advertising certain product (even Chessbase funs/supporters are far less flagrant). I am not going into the nature of business relation between M Ansari and Vasik Rajlich but posts like his should not be allowed in the present advertising form.

Is he exhorting members to buy Rybka? If he's not, then he's not breaking the charter.

it is getting a bit tiresome for you to be constantly attacking the moderators
i notice you did not attack us when you complained about a post and we removed it

a member making real or imagined claims about a commercial engines performance is not an overt commercial exhortation
such a claim should stand or fall on its own merits and be subject to members discussion/scrutiny
we are not here to prevent discussions of this nature
an onvert commercial exhortation is
"go to this web site and buy engine x for $xx"
trying running for moderator on a platform that you will remove all posts dealing with tournament results of commercial engines even before members can answer to it and challenge the results

lets see if you get elected

I usually do not complain to moderation and implying this next to for example Mr. Banks who has more complaints than all other members together is just ridiculous. I did not even complain for the post few lines up when I got asked "from which ass did I crawl" which would be removed by any moderator with a bit of dignity without even complaining.

One thing is providing at least tournament results, TC, play conditions, if not PGN and completely another thing is just repeating like parrot "Rybka 4 is the strongest on LTC, with and without ponder, and on big hardware" without ever offering anything at all but an imaginary respect of the chess community (actually there is respect from Rybka forum members and probably Vas, but nobody with integrity gives a damn about it).
You are obviously pretending not to see the difference and that only tells about you.
