It is related in 2 ways. Firstly, the bits on the top face represent how the bits of the chess board is actually stored in the contract. I chose to highlight this aspect because much of the 250+ hours spent researching and developing the project went into optimizing the system for storing information. Basically, it highlights the code that enables such complex computing, even with the [current] limitations of blockchain computing.

Secondly, the art's traits are determined either directly, or from the hash of the user's move and engine's response. See code/explanation for the full breakdown.

The total supply will be around 1000 NFTs, and minting is free (+ gas). The total supply is not definite until all have been minted because each chess game varies in move count. However, there are move and game count caps: each game is capped at 59 moves, and the number of games is capped at 59. Thus, the total supply will be at least 118 (2 * 59; the quickest checkmates requires 2 moves) and at most 3481 (59 * 59).

A chess engine is a computer that plays chess.

Depth is the number of moves the engine looks ahead. Higher depth requires more gas, but the engine will play a better move.

Although the engine is set to always play black for this project, it can play as both black and white. The engine is also able to analyze and play on any board position, provided that it is legal and has no more than 7 queens per side.

My [real] name has 9 letters, and 5 of them are "e". This project is the genesis project under my real name, hence, fiveoutofnine. It is also partially why the move and game cap are 59.

It is the first project I am releasing under my real name, so I wanted to do something very new to the space. Nearly every component of this project has never been done (or been done very few times) on-chain before: chess, some sort of game-playing AI, non-layered generative art.
