Hi, I'd like to offer PlayStrategy a new game and do the implementation myself.
The game is Yonkoma, designed this month. Two players, two checkers each, on a 10x10 or 12x12 board. Checkers move like bishops and never capture. A move must bring the moved checker closer to the two enemy checkers, measured in king steps, or keep that distance and move the checker away from its partner. Whoever completes a crosscut loses. There are no draws and no dead positions, games run about 30 to 45 plies, and it has no mirroring strategy. Rules: www.marksteeregames.com/Yonkoma_rules.pdf. You can play it against the computer here: www.marksteeregames.com/Yonkoma_play.html.
I've read the four repositories (strategygames, lila, chessground, stratops) and how Entropy was added, so I know this is a new game logic, not a variant, and a fair amount of code. I would do the work with AI assistance (Claude), follow your conventions, and submit it as pull requests in the right order, with tests. I only need to know that you want the game, and if you have a ticket or any design docs that a new game should follow, I'd be glad to have them.
