Home * Engines * Fat Fritz

Unser Fritz [1]

Fat Fritz,
a commercial chess entity by ChessBase, the first version released in August 2019 featuring a set of custom made neural network weights that work in the open source project Leela Chess Zero within its Lc0 executable, while Fat Fritz 2.0 released in February 2021 is based on Stockfish 12 and custom NNUE technology.

Fat Fritz 1

Initially introduced as a cloud project in summer 2019, inspired by DeepMind's ground breaking AlphaZero approach combining Deep learning with Monte-Carlo Tree Search (MCTS) [2], and Albert Silver's Deus X experience, relaxing Leela Chess' "Zero" paradigm of pure reinforcement learning due to supervised learning, Fat Fritz was released in November 2019 as part the Fritz 17 package, best supported by a GPU card such as Nvidia GeForce 20 series. The project and its underlying techniques were emphasized by a talk of AlphaZero co-author Thore Graepel at ChessBase, attended by German computer chess icon Thomas Nitsche along with his sons and Math42 authors Raphael Nitsche and Maxim Nitsche [3]. Fat Fritz was further supported by Daniel Uranga [4] [5].

Fat Fritz 2

Fat Fritz 2 is based on NNUE technology using Stockfish NNUE aka Stockfish 12 with a customized, double sized network, and thus, does not require GPU graphic cards for game playing [7]. The network was trained by Albert Silver using the original Fat Fritz, reinforced by Stockfish's alpha-beta search [8].
