A Stockfish projekt, amely GPLv3 licenc alatt forgalmaznak, perelt a ChessBase c\u00e9ggel szemben, visszavonva a GPL licencet a k\u00f3dja felhaszn\u00e1l\u00e1s\u00e1ra. A Stockfish a legjobb sakkmotor, amelyet a lichess.org \u00e9s a chess.com sakk szolg\u00e1ltat\u00e1sokban haszn\u00e1lnak. A keresetet azzal indokolt\u00e1k, hogy a Stockfish k\u00f3dj\u00e1t proprietary term\u00e9kbe illesztett\u00e9k an\u00e9lk\u00fcl, hogy a sz\u00e1rmaz\u00e9kos munka forr\u00e1sk\u00f3dj\u00e1t megnyitott\u00e1k volna. <\/p>\n
A ChessBase c\u00e9g, amely a 1990-es \u00e9vek \u00f3ta ismert a Fritz sakkprogramj\u00e1r\u00f3l. 2019-ben kiadta a Fat Fritz motort, amely a Leela Chess Zero ny\u00edlt forr\u00e1sk\u00f3d\u00fa motor neur\u00e1lis h\u00e1l\u00f3zat\u00e1n alapul, amely egy\u00e9bk\u00e9nt az AlphaZero projekt eredm\u00e9nyeire \u00e9p\u00fclt, amelyet a Google jelentett be. Ez nem volt jogszab\u00e1lys\u00e9rt\u00e9s, b\u00e1r a Leela fejleszt\u0151i el\u00e9gedetlenek voltak azzal, hogy a ChessBase \u00f6n\u00e1ll\u00f3 fejleszt\u00e9sk\u00e9nt pozicion\u00e1lta a Fat Fritz-t, an\u00e9lk\u00fcl, hogy elismerte volna az AlphaZero \u00e9s a LeelaZero csapat munk\u00e1j\u00e1t. <\/p>\n
2020-ban a ChessBase kiadta a Fat Fritz 2.0 term\u00e9ket, amely a Stockfish 12 motorra \u00e9p\u00fcl \u00e9s saj\u00e1t NNUE (Efficiently Updatable Neural Networks) architekt\u00far\u00e1val rendelkezik. A Stockfish csapata \u00fcgyv\u00e9dekkel egy\u00fctt siker\u00fclt el\u00e9rnie, hogy a Fat Fritz 2.0 szoftvert visszah\u00edvj\u00e1k a n\u00e9met DVD-keresked\u0151kt\u0151l, de az eredm\u00e9nnyel el\u00e9gedetlen\u00fcl visszavonta a ChessBase-t\u0151l a Stockfish GPL licenc\u00e9t, \u00e9s pert ind\u00edtott. <\/p>\n
Ez nem az els\u0151 \u00e9vad a Stockfish k\u00f3dja k\u00f6r\u00fcli dr\u00e1m\u00e1kra, amelyet a kereskedelmi motorok figyelmen k\u00edv\u00fcl hagyva haszn\u00e1lnak a GPL-t. P\u00e9ld\u00e1ul kor\u00e1bban t\u00f6rt\u00e9nt egy eset, amikor a Houdini 6 kereskedelmi motor forr\u00e1sk\u00f3dja kisziv\u00e1rgott, ami azt mutatta, hogy az Stockfish k\u00f3dj\u00e1ra \u00e9p\u00fcl. A Houdini 5 r\u00e9szt vett a TCEC versenyben \u00e9s eljutott a kilencedik szezon szuperd\u00f6nt\u0151j\u00e9be, de v\u00e9g\u00fcl alulmaradt a Stockfish-sel szemben. 2017-ben a k\u00f6vetkez\u0151 Houdini 6 verzi\u00f3 megnyerte a TCEC tizedik szezonj\u00e1nak szuperd\u00f6nt\u0151j\u00e9t a Komodo ellen. A 2020-ban kisziv\u00e1rgott forr\u00e1sk\u00f3dok felfedt\u00e9k ezt a t\u00f6rv\u00e9nytelen csal\u00e1st, amely megs\u00e9rti a FOSS egyik alapk\u00f6v\u00e9t - a GPL-t. <\/p>\n
