Add Chess with Jev (games)

[cwdx]

Adds Chess with Jev to games.

What it is: browser chess and Chess960. Play Jev, a simple engine or a friend, or watch Jev play itself or the engine.

How it uses Jev: each turn the server replays the game, works out every legal move's facts in code (exchanges played out to a net result, mate in one or two allowed or forced, attackers and defenders, threats, repetition), and asks Jev one Choice whose options are exactly the legal moves, plus a Noul (king danger) and two Scores in the same call. Jev can only answer with a legal move; its top candidates show as probability bars and as arrows on the board.

Source: https://github.com/cwdx/chess-with-jev, the Jev client (MIT) and the chess engine (GPL-3.0) that choose each move: the move facts, the Choice sent to Jev, and the re-ask. The site around them is private.

Disclosure: I built it (Chris Wijnia), with Claude Code assisting.
