- 2player resign is draw

 - "when I paste in the same position as 2-Player-Chess, stalemating the opponent gives 15 points to the opponent, and so loses the game, and I can't even view the entire game, as the computer claims that castling was an illegal move."

>when I paste in the same position as 2-Player-Chess

how did you create that game?

if the fen inlcudes "twoPlayer:true", black's kingside is yellow's queenside!

in positions where the king is not on it's usual file, you can still castle, but 960 style. (for example omatamix setup)

in fact castling is now supported for any given startFen(!)

2. γb5-c6 .. O-O-O

 

still todo is a 960 twoplayer position generator.

 

edit: also todo: this pgn won't load (but you can play the moves)

you can castle with elephants, wasn't sure about other pieces. the issue is: i have it search for the first rook/elephant on either side of the k to determine the ks and qs rook.

I-I_I-I

bots are confused by 2pc antichess. they will sit and let the clock run out.

i discovered the first case of getting out of triplecheck without moving the king.

any other cases? maybe something combining king captures?

In this game of Fog of War, involving fairy pieces, I could not see some of the pieces on squares attacked by my Dabba-Riders.

spacebar

which move, which squares? were you able to legally move there, or is there a legal move error?

fyi i just upated with some fixes.

acgusta2

It seems fixed now.  I was thinking that since the Elephant can castle on the test server, we could have it so that the queen, and amazon can castle the royal piece as well, considering that both of the have the movement of the rook as well.  Also maybe we could allow vertical castling.

spacebar

did you read #5? how does it know it shouldn't castle with the Q in the standard setup?

acgusta2

Maybe it could be set up so that you select what pieces you can castle with, so in the standard set up, by default only rooks would be selected as an option for castling.

An idea I also was having is that there should be something similar to a draw offer button, for dead positions that don't cause the game to automatically end, in which if everyone agrees to end the game, then the remaining players get the same number of points as they would get from 3 fold repetition, or 50 moves.

in 2player antichess it does not read my first move unless i refresh the page

using Chrome Versión 81.0.4044.129 (Build oficial) (64 bits)

Windows  8.1 Pro

Premove is not working also.

thanks. should work again now.

acgusta2

I found that the Elephant currently only has the movement of the rook.

thanks, fixed.

2player 960 should work too now, but castling is still buggy (confuses KS and QS)

acgusta2

In order to make Courier Chess more true to its medieval form I edited it so that pawns can't move two squares on their first move, and made it so that castling isn't allowed as I couldn't find anything saying that castling was allowed in Courier Chess, and I know that in many of the ancient variants castling wasn't allowed.  I also read that the rules regarding stalemate have been lost, but it may have been played in some cases with stalemating the other player as a win, and in some cases with stalemate as a draw, so I think stalemating ones opponent being a win should be added as an option for Courier Chess.

 "stalemate is a loss" could be added as a rule variant at some point later on..
