I made a chess engine today, and made it fit within 2KB. I used a variant of MinMax called Negamax, with alpha beta pruning. For the board representation I have used a 120-cell "mailbox". I managed to squeeze in checkmate/stalemate in there, after trimming out some edge cases. I am a great fan of demoscene (computer art subculture) since middle school, and hence it was a ritual i had to perform. For estimating the Elo, I measured 240 automated games against Stockfish Elo levels (1320 to 1600) under fixed depth-5 and some constrained rules, using equal color distribution. Then converted…

I made a website where you can play chess puzzles against Stockfish! When playing puzzles, neither Lichess nor Chess.com will accept a wrong move, which in my opinion spoils the resolution of the puzzle since only correct moves allow you to keep playing. So, I had the idea for a website where you can play chess puzzles, but if you make the wrong move, the puzzle turns into a game against Stockfish. This opens the door to either find alternative solutions or fail miserably (at some point you realize you are not following the puzzle any more). I think its a more engaging way to play puzzles!…

Thought I would post in celebration of 1 year of my website being online. I've been working on it on and off and currently the website allows users to play Hex, Tumbleweed, Amazons, and Connect 6 against friends or against practice bots. I've been a long time player of some of these games and I felt for a long time that the world could use a few more popular abstract strategy games compared to Chess or Go. If you try it, let me know what you think. I'm always looking for new games or new features to add :)

I've been working on Athena Crisis for about two years, and full time for the past 9 months. The game is entirely built from scratch using React and CSS without a game engine. It runs anywhere, including the Steam Deck. You can even use a gamepad on the landing page to play! Previously the landing page had a video of the game but my goal was to always just put the actual game on the website. I merged the landing page into the game's monorepo, added the game's React components, and boom – the video was replaced with a playable version of Athena Crisis. Of course, the real game has tons more…

Hi HN! I wanted to share with you a chess analysis tool that I was building for the past week. First of all I want to explain what is the problem that I'm trying to solve: Chess Engines such as stockfish are superior for us humans, but it's not self explanatory. A player can review their game by stockfish and it will tell them that some moves are very bad and losing, but why? This is the problem that we are trying to solve. ChessRabbit acts as a chess agent with stockfish evaluation tools. It takes every move that the player plays and it reasons about it, with the help, validation, and…

We built ChessBoss at the TechCrunch Disrupt hackathon this week. It didn’t make the top 10 but I thought Hacker News might think it’s pretty cool. https://devpost.com/software/chess-boss There are these really cool smart chessboards that can suggest moves and track your games... but they’re $400 and weigh 19 pounds. And of course there are apps that can analyze games but tracking and inputting games by hand is a huge pain. Or fully-digital chess apps... but board games are way more fun in real life! We wondered: “why can’t you just do that in software and bring the best…
