So in italian there are the same wrong word creations as in the english text. So he is probably no native italian speaker, and i would guess he is the same person with some english and italian knowledge.
Perhaps someone that spent some time in Italy for various reasons. There are a lot of people from east Europe in Italy that work / study for a period of time....but I think that, also if he used a dictionary, he should have a grasp of written italian that is very different from spoken one that is the only language that foreign people (if not students) learn after a bit of time in Italy.
To learn written italian is completely another different story, you need to go to school and spend several years. I have some foreign friends that know how to speak more or less in italian and understand also well but are unable to write correctly because they never studied it.

- It seems to be a "normal" organized program in several c- and header files. I can't find any similarities to an open-source programs I know. The program seems to be written by an Italian, but my knowledge of that language is not good enough that I can decide if the source code is written by a human or generated somehow. Also there aren't any comments, but in total is much better readable and understandable than the Ippolito sources.
- If RobboLitto is a successor of Ippolito then some progress has been made in the regard of stability. There wasn't a single crash in some hundreds games here.
- It comes with a program to generate its own kind of endgame tablebases. At least this part seems to be an original work.

P.S. It seems to be a real monster. In a test at blitz time controls (2+2) it got this results here:
I neither claim it's an original work nor I'd like to defend any cloner. But it seems to be a good idea to take a second look at the new sources too.

Thanks Volker for your statement,extremely interesting
One question though:
Can it be compiled for the Windows operation system
Cheers,

It was OK for Vas to take other ideas when he was the one who "took" them.
Yep,it was ok for him but now he's not

It shouldn't be to difficult for someone who does such ports sometimes. I'm not the one who can do it cause I'm simply missing a compiler for Windows.
However, Marco's comments about the mistakes in the Italian are interesting. What makes me wonder is that there aren't any comments in the source code. The speed how fast one forgets what he has programmed himself without comments is amazing. OTOH there are these tablebases.

As a programmer I can say that is _impossible_ to work an a source like the one posted.
What I think is that there is one properly edited and commented source that this guy uses to develop and then when he has to post to public takes this 'good' source, strips comments, unify in one single big file, shuffles the formatting and gives it to the C preprocessor the result of this obfuscation process is what we see published on the site.
I could easily to the same with Stockfish and I would bet anyone of you to reconize the original from the obfuscated one although the functionality remains 100% the same up to the last bit.
I think he is doing like this to give the reader a bit of fun trying to understand what's in it.

I find neither version hard at all to understand. I aso do not think they were decompiled since variable names make sense and are easy to understand. I donlt even need to look at an Italian dictionary since you can tell from what calls what the purpose of things. My guess is the authors merely looked at the assembly code from other programs and combined the best ideas of each in a new program. Is stealing ideas illegal or wrong? Well, I personally think stealing an idea without credit is wrong. But is it a copyright or patent violation? I assume Vas has not patented the ideas in Rybka, so probably not that. In any case, the computer chess market is so small that any profits a programmer makes writing this code would be totally gobbled up by lawyers if they even tried to sue.
If these programs are stronger than Rybka, I am sure with an hour of source code viewing, Vas could understand any beneficial changes. With all his work on Rybka 4, I have no doubts that he will be well ahead of these programs very soon (and probably already is).
