   Sameshi – a ~1200 Elo chess engine that fits within 2KB▲230

   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…

   OffChess – Offline chess puzzles app▲369

   Hi HN! I'm the developer of rdx, a mildly popular ad-free, privacy and user friendly Reddit client. This time, I made something for a very specific use case: solving chess puzzles with no internet. Why? Well, my Wi-Fi is terrible in the bathroom—and that's where I do some of my best thinking. I tried printing out “mate in X” puzzles to solve offline, but they weren’t fun without interaction. So I built OffChess. OffChess is an iPhone/Android app that contains over 100,000 chess puzzles, fully offline and completely ad-free. You can solve puzzles by category (Mate in…

   Matle – A Daily Chess Puzzle Inspired by Wordle▲85

   Hi HN, Matle is a daily chess puzzle inspired by Wordle. You're shown a checkmate position with 5 hidden squares, and your goal is to guess what’s on them to complete the mate. Someone kindly shared it here a few months ago before I had the chance to post it myself. I’m the creator, and wanted to share a few new features based on feedback, and hear your thoughts. You can now view the original game behind each puzzle, get explanations for why a guess isn’t checkmate, and see daily solving stats. Would love to hear what you think: https://matle.io

    ChessWoodie▲26

    I built ChessWoodie as a platform for structured chess tactics training. Most puzzle trainers give you random puzzles. That can help calculation, but it also means you rarely see the same pattern twice, which makes it harder to build fast pattern recognition. ChessWoodie organizes puzzles into courses where the same positions repeat across training cycles. The approach is inspired by the Woodpecker Method: solving the same puzzles repeatedly until the patterns become automatic. You can try it directly in the browser. There’s a guest login if you want to jump straight into solving puzzles.…

    Chess Twist▲29

    I continue my experiment of transposing classic games onto an irregular grid. I've previously released variants of minesweeper and checkers. And now I'd like to share my variant of Chess. Chess can be a pretty punishing game, but I thought this was nevertheless a way to make it even more challenging by making it trickier to anticipate your opponent, even though both players still have the same information. From the playtests I've done, that challenge is pretty compelling. It also seems to be more fun at 2 people, where both players keep surprising one another.
