Info about Leela Zero:
en.wikipedia.o...
...
Leela Chess Zero (lc0) is a free, open-source, and neural network-based chess engine and distributed computing project.
Leela Zero's algorithm is based on DeepMind's 2017 paper about AlphaGo Zero.[3][6] Unlike the original Leela, which has a lot of human knowledge and heuristics programmed into it, Leela Zero only knows the basic rules and nothing more.[7]
Leela Zero is trained by a distributed effort, which is coordinated at the Leela Zero website. Members of the community provide computing resources by running the client, which generates self-play games and submits them to the server. The self-play games are used to train newer networks. Generally, over 500 clients have connected to the server to contribute resources.[7] The community has provided high quality code contributions as well.[7]
Leela Zero finished third at the BerryGenomics Cup World AI Go Tournament in Fuzhou, Fujian, China on 28 April 2018.[8]
Info about Alphazero:
en.wikipedia.o...
AlphaZero is a computer program developed by the Alphabet-owned AI research company DeepMind, which uses an approach similar to AlphaGo Zero's to master not just Go, but also chess and shogi. On December 5, 2017 the DeepMind team released a preprint introducing AlphaZero, which, within 24 hours, achieved a superhuman level of play in these three games by defeating world-champion programs, Stockfish, elmo, and the 3-day version of AlphaGo Zero, in each case making use of custom tensor processing units (TPUs) that the Google programs were optimized to make use of.[1] AlphaZero was trained solely via "self-play" using 5,000 first-generation TPUs to generate the games and 64 second-generation TPUs to train the neural networks, all in parallel, with no access to opening books or endgame tables. After just four hours of training, DeepMind estimated AlphaZero was playing at a higher Elo rating than Stockfish; after 9 hours of training, the algorithm decisively defeated Stockfish 8 in a time-controlled 100-game tournament (28 wins, 0 losses, and 72 draws).[1][2][3] The trained algorithm played on a single machine with four TPUs.

Relation to AlphaGo Zero
Further information: AlphaGo Zero
AlphaZero (AZ) is a more generalized variant of the AlphaGo Zero (AGZ) algorithm, and is able to play shogi and chess as well as Go. Differences between AZ and AGZ include:[1]
AZ has hard-coded rules for setting search hyperparameters.
The neural network is now updated continually.
Go (unlike Chess) is symmetric under certain reflections and rotations; AlphaGo Zero was programmed to take advantage of these symmetries. AlphaZero is not.
Chess can end in a draw unlike Go; therefore AlphaZero can take into account the possibility of a drawn game.

Replayable game with indented variations: www.chessworld.net/chessclubs/ltpgnviewer32/ltpgnboard.asp?GameID=5024018

[@joseraulcapablanca8564]

a fascinating game and an illuminating analysis. thanks KC keep up the good work

[@shanelevene4864]

Thanks as ever KC. A freezing morning here in Shepherd's Bush so needed something with my coffee to help defrost me properly. X

[@kingscrusher]

Cheers, K

[@kayeven]

Amazing game again! The power of the bishop and rooks

[@kingscrusher]

Cheers, K

[@Bobby-fj8mk]

Very well explained positions and a great win from a neural network. White seemed to be in charge for most of the game. It is always difficult to avoid a draw with opposite colour Bishops.

@@kingscrusher Thanks KV - do what I did - I tried to play Stockfish 10 - guess what? It checkmated me in 25 moves - oh dear - LOL. At least I can beat Chess Titans on level 10 most of the time.

[@FreethinkingSecularist]

@@Bobby-fj8mk is that the free chess game on windows? If so I know it isn't great at level 10 because I beat it too at the highest level and I am only 1300ish

[@Bobby-fj8mk]

@@FreethinkingSecularist - Hi there Mr Free - Yes Chess Titans is the free chess program that is part of Windows 7. I tried to find its rating and most chess forums have it at about 1600 to 1700. I can beat it 80% of the time on the highest, level 10. At least its a program where a human can have a chance to win. Stockfish 10 just annihilates you no matter what you do. It's rating is way above even a Grand Master.

[@FreethinkingSecularist]

@@Bobby-fj8mk well I may have had a lucky game, or more optimistically(or delusional) I am better than I think. Lol cheers and thanks for responding.

[@12InchesUnBuffed]

Fun Video - Cheers, 12.
