Sorry for the spam. This release was originally announced as 5.07.175b in the programmers forum but it was suggested that I bump the version number
and repost it here.

According to my testing GNU Chess 5.50 is about 120 elo (+-20) stronger than Fruit 2.1 at 40/4 time control, 128Mb hash.
I think it is a good milestone since it is the first GNU Chess 5 which is substantially stronger than GNU Chess 6.

Re: GNU Chess 5.50
I did not really measure this.How much stronger is it than GNU Chess 5.07.173b ?
But 5.07.173b is 2603 at the CCRL (40/4) and Fruit 2.1 is 2687. So if my measurement of the difference between Fruit 2.1 and 5.50 is correct then the difference between 5.07.173b and 5.50 should be about 200 elo.
This is just an estimate as there are huge error bars everywhere. In particular
this estimate would contradict somewhat the fact that 5.50 is weaker than Glaurung 2.2.

Re: GNU Chess 5.50
OK thanks, well I will run it at chess960 and find out, assuming it still plays that.

Re: GNU Chess 5.50
After the first 600 chess960 games, that is about right. Many more games to go though.Michel wrote:I did not really measure this.How much stronger is it than GNU Chess 5.07.173b ?
