How far are we from the solution of atomic? • page 2/2 • General Chess Discussion • lichess.org

Sorry for the late reply, did not log in to this account for a while, I was out of city.

@risky-chess I did not make them play in order to solve atomic, but to see how they play.

We all know SF does not understand atomic fully, and it plays some quite dubious lines.
In fact, in the game I recorded ( here is the video, it is very long, watch it in x2: www.youtube.com/watch?v=eJbhRKl7_sM ), it plays 1. Nf3 f6 2. e3 d6?, which is probably refuted by 3. Nc3 c6 4. Ng5 fxg5 5. Nd5 cxd5 6. Qh5+ g6 7. Qb5+ Nc6 8. Qb6 axb6 9. Bb5+ Kf7 10. Be8+ Ke6 11. f4. And it replies as white with 3. Nd4, about which I do not have much information.

@cat_person Making a neural net playing atomic sounds very cool, please inform me when you start it.

@savagechess2k That game is of very old version of stockfish released in 2016... Should use much newer versions and will have much better games.

@savagechess2k 1. Nf3 f6 2. e3 d6 3. Nd4 is quite strong, too but 3. Nc3 is simpler

For my part I have started to build an atomic book in the cloud. Every position is analyzed in infinite multipv mode at a relatively shallow depth ( depth 15 currently ). In every position always the best move is played, except for positions very close to the root, where more than one move in a position gets a chance to be played ( 3 best moves for white in the root position and 2 best responses for black on the next halfmove currently ). After certain number of nodes added ( which is 20 nodes currently ), the tree is minimaxed out and saved back to the cloud. This is repeated in a cycle, so the book slowly gets built up. The book builder itself also runs in the cloud.

Currently everything is beta.

You can have a look at the current state of the book, by visiting

fbserv.herokuapp.com/analysis/atomic

and switching to the "Auto" tab.

The first yellow column shows the move in SAN notation ( with "..." added if there is further pv behind the move ), the second, green column shows the mimimaxed out evaluation in centipawns, the third, blue column shows the engine depth and the forth, gray column shows the engine score ( as analyzed by the engine originally ) in centipawns.
