Play against well-known chess players' openings▲5
Hi, this is my first HN submission so please forgive the rough edges. For this project gathered chess positions from some well-known chess players with a lot of games. (Usually ~25k games and 1M+ positions. The most for any player was GM Aman Hambleton with 1.8M positions indexed.) With each board position I create a probability distribution of moves the player has made from that position. Then, I simply draw from that distribution (with sampling temperature) to choose a move. As long as there's at least one game with a given position, you can keep playing. You'll see that it's pretty easy…

I built a chess explorer that explains strategy instead of just stats▲14
I built this because I got tired of Stockfish giving me evaluations (+0.5) without explaining the actual plan. Most opening explorers focus on statistics (Win/Loss/Draw). I wanted a tool that explains the strategic intent behind the moves (e.g., "White plays c4 to clamp down on d5" vs just "White plays c4"). The Project: Comprehensive Database: I’ve mapped and annotated over 3,500 named opening variations. It covers everything from main lines (Ruy Lopez, Sicilian) to deep sidelines. Strategic Visualization: The UI highlights key squares and draws arrows based on the textual…

Learn Basic Chess Movements▲12
I made this basic website for my daughter (6) to learn how to move chess pieces. I wanted a simple game which didn't have all the rules, just how to get from A to B with a piece. Admittedly, as soon as I made this a friend pointed out https://lichess.org/learn which is really nice! There are a bunch of settings you can tweak to set the difficulty etc. Anyway, maybe will be a fun (short) diversion.
