Spot on with castling and pawns! One idea is to allow pawns to jump from 1 to 3, I believe that’s how it’s done in horde.

Nice setup ideas! Beating the bot is quite hard, so maybe you are professional? :) If you want to make the bot even smarter, you can increase depth and think time in settings

Thank you a lot for the review and great ideas, we’ll be working to add the suggested features!

Castling is possible if king and rook were spawned on the standard chess positions and hadn’t moved (e.g. king on e1 and rook on a1)

Pawns move two squares from the second row only.

There is an option to save your setup (for registered users) and also option to set up for computer (in computer settings).

Tournament is a super idea, neat way to make a theory of setups:)

Awesome ideas with the initial position transcript and permalinks, we’ll work on the implementation!

Each opponent sets up for themselves so by default computer makes its own setup

In computer settings you can toggle manual setup for computer, which allows you to set up for computer

You can also let computer play against itself! Make two setups and see which one is stronger

Looking forward to see!

39 is the total in standard chess - if you sum up values of a queen, 2 rooks, 2 bishops, 2 knights, and 8 pawns the result is 39. King should be on board but doesn’t count towards the total since it’s basically infinite

Make any starting position with 39 points of material. When players are ready the setups are revealed and normal chess rules apply.

Play against computer, with a friend, or multiplayer

even with long term storage?

I am really impressed with codex cli on gpt 5 codex high

It seems like it has a better overview of a codebase (whereas sonnet picks up bits), which allows it to make more advanced features

Will AI companies ever be profitable?

Even OpenAI, $500B valuation with ~$10B sales, 50 P/S ratio with high cash burn

And it’s unlikely users will agree to higher prices with so many open source alternatives
