This is a variation of chess in which, in addition to the arrangement of the pieces, the rules governing pawn movement are altered, and new rules are introduced:

Called Diagonals, Diago, or DiagoChess. Standard 8x8 board. White sets up in the bottom-right corner (King on h1) and moves first; Black sets up in the top-left corner (King on a8).

Movement: Kings, Queens, Rooks, Bishops, and Knights move normally. Pawns move 1 square in any direction to empty squares, but capture strictly diagonally.

Special Rules: No check, checkmate, castling, pawn promotion, or en passant.

Win Conditions: First player to capture the enemy King wins immediately.

Attacked King Mechanics:

Streak Reset: The attacked turn counter resets to zero as soon as your turn starts with your King safe.

You can play this version on the website; I've added full-fledged multiplayer with the ability to create public and private rooms. The multiplayer is powered by NOSTR (nostr relays).

The website features a game against a bot at various difficulty levels, single-screen gameplay, online matches against other players, a time limit like in chess, and even a profile (either as a guest by entering just a nickname, or via Nostr).

The computer plays too fast. Even if the computer is not thinking, add a 1 second delay.

I played a game at at the end I had a rook and a few pawns, and the computer had a few pawns, and I won immediately. Did the computer resign? The sign on the screen looks like a telling a weird rule.

hey, there's a bug with the timer. when playing against the bot, only my clock is running. and the bot thinks for a long time (on expert lvl), so if the clock worked properly it could easily lose on time. you'd just need to drag the game out.

also, once I lost with the message "White cannot defend the king. Black wins." but that wasn't true, I still had moves with my king.
