No ads, no accounts, just a hobby project.

For the past few months I've been building Chess Codex a free, no-signup encyclopedia of all 3,690 named chess openings indexed by Lichess (public-domain ECO data).

Live: https://test.av-webdevs.com/

The goal was to make a reference I personally wanted but couldn't find: something between Chess.com paywalled explorer and Lichess's search-focused explorer. Every opening gets its own page with:

-Interactive board - click through the moves or use arrow keys

-Live Lichess statistics - win rates and top responses for each position, pulled from real games, cached server-side

-Stockfish evaluation - cached from Lichess cloud analysis (slowly growing as I batch-fetch)

-Tree navigation - parent line, sibling variations, full subtree of every sub-line at all depths

-Play from here vs Stockfish at six difficulty levels (built on Stockfish.wasm, runs in your browser)

-Search by moves, name, or FEN (the FEN search finds transpositions - same position reached through different move orders)

It's a hobby project, written in vanilla PHP, hosted on shared OVH for 39 nok/month (€3). No ads, no tracking, no signup. Mobile-friendly + installable as a PWA.

main body

Things I'm still working on:

-Human-written descriptions (currently 25 done, 3,665 to go - there's a "Suggest an improvement" form if you want to contribute one for your favourite line)

-Translations of opening names to UK/DE/FR

-Engine evaluations for deeper variations (Lichess only caches popularpositions)

Would love feedback - especially on UX (mobile in particular), missing

features, or openings I should prioritise for hand-written descriptions.

I have created a prototype of a chess where every few turns you can upgrade on of the pieces to gain additional moves. It’s available at https://chess-upgraded.com with full source code available in GitHub.
Personally I enjoy how the king can escape checkmate via the teleport; I’m not sure how good the rest of the dynamics are, so looking forward for any feedback.
The game is playable online vs other players of vs computer

Hey everyone, I’ve been thinking about the transition from 2D chess to spatial 3D environments on the Vision Pro:

1. Why 3D: If you already play online, what would actually make you put on a headset to play in 3D instead of just using your phone or a physical board?
2. Customization: What matters most to you in a spatial chess app—the Theme, the Environment (being able to customise it), or the Chess Pieces/Board itself?

8 x 12, no en passant, the pawns can move up to 3 squares on their first move.

My invitation into the Rabbit Hole ;) Let's have some fun!

The rules are simple – find and destroy all 16 opponent's Kings. Whoever loses their last King loses the game. All pieces move and capture like in standard chess. Oh, and most importantly – when a piece captures, it disappears together with its victim. It's the Rabbit Hole, after all...

SHUFFLE BAFFLE

Full Board Random Chess

For fun and entertainment only.

The Theme

No openings to memorize. No predictable setups. Just a shuffled board where the starting position baffles you from move one. Pure chaos. Pure fun.

Board & Setup

Board: Standard 8×8 chessboard

Pieces per side: 16 Kings, 4 Queens, 4 Rooks, 4 Bishops, 4 Knights

Total pieces on the board: 64 (32 per side)

Starting position: All pieces are placed randomly anywhere on the board (both players' pieces mixed together). Each player has their own 32 pieces, but they are shuffled and placed randomly across all 64 squares.

Movement & Capture

Kings, Queens, Rooks, Bishops, Knights – move exactly as in standard chess but DIE ON CAPTURE.

No pawns.

No castling.

No check, no checkmate, no stalemate. The King has no special status – it is just another piece that can be captured like any other.

Multiple Kings Rule

All 16 Kings on each side move and capture exactly like a standard chess King (one square in any direction).

Kings can be placed next to each other – no restriction.

Kings can be captured. Losing a King is like losing any other piece.

Goal

Destroy all 16 opponent Kings. The first player to capture the last remaining King of the opponent wins.

All other pieces (Queens, Rooks, Bishops, Knights) are secondary – they exist to help you hunt down the Kings. You do not need to capture them to win, but they can get in your way.

Draw Conditions

A draw occurs if:

Both players agree to a draw.

50 consecutive moves are made without a capture (standard chess rule).

Why "Shuffle Baffle"?

Because the setup shuffles everything across the entire board, and the resulting chaos will baffle even experienced players. No two games are ever the same.

Play Online

You can play Shuffle Baffle online against real opponents or bots on GridGrove.gg.

For those who don't know, the normal chess we play every day is 2 dimensions chess. The chessboard is a flat 2D shape, and the pieces also move in two dimensions. But in 3 dimensions chess, additional boards are stacked on top of each other and it looks like 8 chess boards are stacked, so the movement of the pieces takes place in three dimensions. I don’t know exactly how the pieces move in 3D.
