lavren1974··on Classical chess ranks 562nd of 960 starting positions after 460,800 games
That is what this is. White and Black get different back ranks. Every one of the 960 setups plays every other one, with both colors. So 921,600 games, and each single game is a double random position.

Classical is 562nd of 960 by score so far. The article did not make that clear, which is on me.

Author here. Yes, the article was written by an LLM. My English is not good enough for that text and I did not want to spend a week on it.

The reason is simple. I built this because I wanted the answer for myself. I still don't know if it is useful to anyone else. So I put my effort into running the tournament and almost none into writing about it. Clearly that shows.

The tournament is real. Stockfish 15.1 with NNUE turned off, same time control and same hardware for every game. 460,800 games played, 921,600 total. No model touched the numbers.

lavren1974··on Chess960v2 : All 960 Fischer openings analyzed, full restart planned after fix
At chess960v2.com, I'm running a full analysis of all 960 Fischer random chess starting positions using Stockfish self-play. Over 50% of the games have been completed — and while initial results looked stable, a deep review revealed a troubling anomaly: no castling occurred in any game.

The cause wasn't time pressure (0.5s per move), but a logical bug in the system: although castling was technically possible, the engine failed to recognize valid conditions during play. This distorted the data significantly, as castling is a key strategic element, especially in asymmetric setups.

The bug has now been found and fixed. A full restart with clean data is planned. The time control will be increased from 0.5s to 1 second per move — improving stability and evaluation quality, though the core issue was logical, not temporal.

The project is open-source — code is available for anyone to run longer sessions (5s, 30s, 1min+) to study position balance and fairness.

Upcoming features include online multiplayer with custom starting positions, and later, a hidden pieces mode (in development), where only pawns are shown, and players must scout to discover the true location of enemy pieces.

Brief downtime may occur in 1–2 days due to an IP address change. Feedback welcome, especially from those interested in chess asymmetry, engine-driven analysis, and novel game design.

lavren1974··on Show HN: Chess960^2 is now open source
No, not yet. Right now it's a tournament where Stockfish plays against itself from different starting positions — each of the 960 white setups will play against each of the 960 black setups (a full tournament will consist of 921,600 games). This is an experiment to understand which starting positions are most balanced. In about a week, online play will be available, where each player can create their own starting position (it's almost ready, just waiting for my day off).

Interesting! I launched the chess960v2.com project a couple of days ago! I'm actively working on the online game, and I think it'll be ready in a couple of days. Why 39 points of material?

I really like Codex; the subscription with the chatbot and agent is just wonderful. I don't even want anyone to praise it, otherwise they'll probably launch additional monetization.

And this is fueling tension. Everyone's been violating airspace a little bit (I used to be a military pilot myself), but now they're getting hysterical, and apparently for good reason, they're trying to escalate the situation.
