Chiron 5 Released

[Damir]

Thanks for the news on this. I checked my email and did receive a link with discounted price (15$ USD).

Just received the link. That was fast, look forward to testing it out.

Hi Ted

Can you tell me how long it took for you to receive the download link after purchasing the engine?

I have checked my mail and still no download link, only a mail from paypal confirming my Chiron 5 buy... but no download link....

[Damir]

Got the link already.. sorry for the incovinience and my impatience.

[mclane]

Can somebody tell me something about the engine ? Origin ? Idea behind it ?!

I enabled Large Pages (Chiron 5) and Used 8 Threads (Both Engines) for this last match. 50 Games, Time Control 5'3. Chiron 5 appears to be stronger than Shredder 13 or at least equal to it. Note each engine used their own opening book. Next up is to test it versus Komodo.

Here is a nice position from game 4 of the match.

Thank you

[Damir]

. . . sorry for the incovinience and my impatience.

. I actually kept checking my emal client waiting for the link, too! My wife thought I was nuts. .

I just got a mail from Andrea where he told me to reinstall Chiron 5 from the same download link. It seems Chiron 5 was underperforming 10-15 elo with something called ''flag'' that he forgot to remove when compiling Chiron 5. He has now removed ''flag'' option so the engine should get additional 10-15 elo in its performance. Might be a good idea for you to reinstall Chiron 5 again and delete the old version.

Thanks for that heads up, I checked my email and sure enough I received the same email.
