kleineme: I would also like it very much if the accurate ratings were in the PGN files. As I am already automatically extracting the header to show the player's names and the result, I could very easily extract the ratings too and then filter the games by rating, which would be very nice.

kleineme: I agree too. More meaningful ratings would also be useful to me when I am looking for nice games by strong players. This would for example avoid that Chessmaster1000's games show a low rating only because he lost a lot of games on time when he left.
Now I suppose that this would require to store information which is not currently stored (or is it?), so some more storage space, and it would still show "incorrect" ratings for games played before this new feature. Is it worth it ?

Sarah1980: In what language ?

Fencer: Yes that remark was a bit pedantic by mine, but indeed it was slightly confusing as well, because there also exist ways to wrap a board into a sphere (at least I know Spherical Chess), which are just more complicated than building a torus. Of course the confusion disappears when reading the rules carefully.

I wonder whether this is the right board for this question, but wouldn't Sphere Froglet be better named Torus Froglet ?

Summertop: I also second that. If pawns would see how funny the smileys were they would know what they are missing.

Summertop: Good idea. Even better with colours reversed ?

grenv: Yes, and the same is true about Recycle Chess.

Fencer: Yes, good question, the link I gave is slightly outdated. It looks like Recycle Chess is now always played with promotion, and it is also the way I played with the inventor some months ago. Of course it makes a huge difference : pawn drops to the seventh rank are very common when playing with promotions.

KotDB: I love Bughouse, believe me, but I don't support it to be implemented here. Bughouse requires to be live and fast-paced to be of any fun. To play it turn-based you would probably have to set up an order of play like (boards are A,B) A white - B white - A black - B black - A white ... It has been done but I don't think that it has been fun :-)
As for Crazyhouse, I fail to see why it should be better than Loop Chess (generally named Chessgi). The only difference is that in Crazyhouse a promoted piece return to pawn after it is captured. The reason of this special promotion rule is obviously to copy over-the-board Bughouse, where you don't have time to seek for a promoted piece and you continue to play with one or more pawns which have the power of a queen ; it is already hard to remember that they were promoted while they stay over the board but it would be impossible to remember it once they are taken, so the only way to handle promoted pieces is to state that they return to normal pawns once captured.
So the only advantage of Crazyhouse over Loop Chess is that Bughouse players are more acquainted to it. This being said, it is less logical, and a completely correct user interface for it would require to place markers on all promoted pieces, as they behave differently from normal pieces once they are captured.
Rather than Crazyhouse, there are two other excellent games in the same family, namely Recycle Chess and Hostage Chess. Recycle is not hard to implement, Hostage is harder.

Marfitalu: The english traduction for that one reads "Knightmare". It is really funny !
