The Bug Thread

Oh wait I thought I made it FFA there should be a capture anything.

I have no audio when I play... Anyone with the same problem?

1. Is your computer muted? Or is there something wrong your computer, rather than chess.com?
2. On your browser, you could've muted the tab.
3. You may have accidentally changed your settings so that everything is on mute.

Green could use his knight to block the rook check, but he'd still be in check from the Red bishop.

I forgot about the bishop lol.

>block with knight
It's double check, Blue discovered Reds bishop

Strange bug with non-coloured pieces ( e.g. P, R, N in the FEN4): If they are included in a position, the position is playable. But when you actually play the position you can't move or resign.

That FEN should really give an error, will fix. because it's not valid, dead pieces need a "d" . dP, dR, dN etc

glitch?

Nope, custom checks, but shouldn't be allowed.

11.001 checks

Suddenly takes a very long time to start a game..

when you type /stop-chat once then join a game it says 'Sorry, your message is identical to the one you sent recently' is this a bug??

lol then it would be 12 checks

Yeah, 27.y in that game should have only given 1 check to blue. Interesting bug.

Information on the scoring system here:

https://www.chess.com/clubs/forum/view/how-the-rating-system-works-1

There's no way to know what your Rating Deviations were at the start of that game. Your current RD is the only one reported.

Is this a bug?

This member joined my game and abandoned but I noticed they have 2000 rapid, 2000 blitz, 2000 bullet with 0 games played. https://www.chess.com/member/eruwere3e434

Now it says their account is closed. When I clicked the name and it gave me the small popup of their stats it showed 2000/2000/2000 on their stats.

I was playing Ox1e+242 (yes that is still possible), and when someone autoclaimed, the point system claimed it was a win, while in the moves said it was a resignation, because it can't calculate the values, and instead calculated the score without the Ox rule.
