Please run project on the fast TurboWarp runtime, where the AI can unfold its full potential: https://turbowarp.org/1033379869 PLEASE READ FAQs PRIOR TO POSTING "BUGS": - NO HANDLING OF INQUIRIES W/O PGN DATA - "There is a bug!" Unlikely, no known issues. Consult experienced player, read instructions. - "Why invalid move?" Likely keeps / puts you in check. - "I still found a bug!" Please describe in detail, and click "Export", then copy & paste FEN (board) or PGN (moves) data into a comment. - "Too difficult!" Switch to level Easy 1 or 2, at which the engine makes semi-random moves. - "Too easy!" Play level Difficult on TurboWarp (a Scratch runtime 50x faster than Scratch 3): https://turbowarp.org/1033379869 If you win against level Difficult, please copy/paste PGN data for analysis (click "Export"). You might have to split PGN data into multiple comments. Scratch is not well suited for CPU-intense calculations (interpreted, missing language features like bitwise operations, slow by design), that is why a Scratch chess engine will always have limited playing strength. TurboWarp is faster, but still has to emulate Scratch, hence has to impose similar restrictions. - "Too slow" On slow systems it is recommended to select a lower playing level. The engine is think time bound, and takes exactly as long as designed. - "How to castle?" Move the king two squares towards the rook; king must not be in check, none of the passed squares must be attacked, and neither king nor rook must have moved before. - "Board is set up incorrectly" Maybe you mixed up king and queen? - "King and queen move the wrong way" Maybe you mixed up king and queen? - "King and rook moved at the same time" That's called 'castling', and is a valid move. - "Opponent pawn captured my pawn which had already passed it by moving two squares before!" That's called 'en-passant', and is a valid move. - "Why is it a draw when the engine mainly has its king left and I still have pieces?". Most likely draw by stalemate (no legal move but also not checked) - "How do I copy FEN or PGN data?" Click "Export", triple-click FEN or PGN data, press Ctrl-C (Windows) or right-click / select "Copy". - "How to play en-passant?" Move your pawn diagonally by one square, behind the opponent pawn which just moved two squares. - "What does the black/white bar on the right side of the board indicate?" It shows the current evaluation of the board, so either black's or white's lead in the game. BUG REPORTS: Please describe exactly what happened, and provide exported board data: Click "Export", then look for the FEN data, select the text by triple-clicking it, copy it to the clipboard and paste it to the bug comment. Alternatively you can also export the move list in PGN format. Please also report the difficulty level. Before you post a bug, go sure it really is a bug and not a misunderstanding, e.g. you may want to consult an experienced chess player beforehand. Thank you!
