As far as I can tell, the more elaborate method gives an even distribution of FRC starting positions.Ichabodhttps://www.blogger.com/profile/18128802270405657672noreply@blogger.comtag:blogger.com,1999:blog-6011690536420808420.post-87444826333253099802011-07-08T18:27:27.435+02:002011-07-08T18:27:27.435+02:00Thanks, Harry, I'll check that out and try to ...Thanks, Harry, I'll check that out and try to analyze it.

To play through a masterpiece is like listening to a masterpiece of music. And when classical chess is solved it can be used in the mathematics school teaching. <br /><br />But the day when classical chess is solved isn't here yet. Players are still winning classical chess games...<br /><br />Many Grandmasters overestimates their possibility to know the best way to play a chess game, and still not be able to win the game, when speaking about changing the rules for classical chess or playing only Chess960. It's too early to call the Petroff, the Berliner Wall, the Queen's Gambit etc for a draw. And if you find a draw against everything you also have to remember the solutions. Well, that's many variations to remember exactly. Not sure many humans are capable of that. <br /><br />Your Chess CoachYour Chess Coachhttps://www.blogger.com/profile/14071882950892096824noreply@blogger.comtag:blogger.com,1999:blog-6011690536420808420.post-37992688771537186002011-07-03T02:37:43.929+02:002011-07-03T02:37:43.929+02:00Mark thank you for the extensive post!

I had no idea of some of these new comments on 960. To have the FIDE vice president support Chess960 in some fashion is simply spectacular news and increases the probability that Chess960 will have a long future. Let's hope so!<br /><br />Mark the only thing you missed out on is to comment on the really big news that Andrei has started a dedicated Chess960 server at http://e-chess960.com/! He has put in an enormous amount of work into it and it still evolving. The point is that he has implemented the Chess960 clock correctly and thus is showing the way for the future of live chess. If you could do a post on their site at one stage I would really appreciate it. The developer and other helpers are really nice and open to ideas. It's definitely worth becoming a member even if it is just to support them and to take a look around.<br /><br />Anyone reading this blog, please support the future of live Chess960 and the hard work of Andrei at http://e-chess960.com/. Become a member if you can!<br /><br />Cheers<br />HarryHarryOhttps://www.blogger.com/profile/15971894954907592580noreply@blogger.comtag:blogger.com,1999:blog-6011690536420808420.post-22836523206745926492011-07-02T23:21:33.100+02:002011-07-02T23:21:33.100+02:00Got it.

That is, pawns 6, 7, and 8 will always be the rooks and the kings. If the rooks and the kings are all on the same color, there are only four ways to place the bishops. If one of the rooks or the king is on a different color, there are six ways to place the bishop. But the pawn ordering don't know that. There are the same number of pawn orderings whether or not the rooks and king are on the same color. So if they are on the same color, you have the same number of orderings going to fewer possible positions, making those positions more likely.<br /><br />Could someone post a note to this effect on Chess.com?

But when I did a brute force check I didn't get an even distribution. I got 96 positions that had a 1 in 672 chance of coming up, and 288 positions that had a 1 in 1,120 chance of coming up (the rest had a 1 in 960 chance of coming up). I'm not entirely sure why, so it might be a problem with my program. It seems that positions with knights on different colors have the right probability, but those with knights on the same colors are either too high or too low. I'll try to do some more analysis and figure it out, but I need to do laundry.Ichabodhttps://www.blogger.com/profile/18128802270405657672noreply@blogger.com
