DeepChess turns raw Stockfish 18 engine data into plain-language coach explanations you can actually learn from. Paste any PGN or game link from lichess or chess.com โ our AI tells you exactly what went wrong with every move, not just "+1.45, Nf3 is best."
Every position is evaluated at tournament depth with MultiPV. The static engine classifies piece safety (safe, loose, hanging, pinned) and detects forks, skewers, and mate threats before the LLM touches anything โ so explanations are grounded in verified data, never hallucinated.
Built for players who are tired of staring at engine lines. One free analysis per day, premium plans for unlimited auto-analysis with accuracy percentages and tier badges.

DeepChess.dev's answer

Hi HN! I build this project to explore an idea I got in mind for a long time : Is transformer a suitable architecture for a chess bot? I built a small model (11M parameters) and trained it on human games (Elite Lichess DB). Model alone is performing around 1500 elo, but I built an harness using Monte Carlos Tree Search (MCTS) using my model heuristics to improve the model to ~2100 elo (evaluated against... - Source: Hacker News / about 1 month ago
Lichess is incredibly well optimized [0] (and an amazing public service). I'm sure that this is very cost effective for TTT, so a win-win. [0] https://lichess.org/@/revoof/blog/optimizing-the-tablebase-server/MetV0ZQd. - Source: Hacker News / 4 months ago

Lichess uses a scheme which is probably more efficient on average, described on revoof's blog[0]. Basically, it's a variable length scheme where the first 64 bits encode square occupancies, followed by piece codes (including castling, side to move, and ep with some trickery), followed by half-move clocks if necessary. 0:... - Source: Hacker News / 7 months ago
