You can analyze your positions and games online with a powerful chess engine - Stockfish. You can import your game in PGN notation or set up a position from a FEN. But if Stockgish 8 is running on anywhere comparable hardware to what A0 used it does indeed find the move. Analysis Board Reproduce and analyze your games or the positions you want. The myth is that A0 could find a move that Stockfish 8 couldn’t. The comparison I seen made was the A0 machine used in the match was about 180 TFlops while a high-range i7 of the time was in the range of 100 Gflops. The training ran on over 5,000 Tensor Processing Units while the actual machine playing in the match used 4. Better hardware makes a huge difference.īefore anyone objects to the suggestion of using server-grade hardware, you have to understand the hardware that A0 was running on. If you run Stockfish 8 on a decent multi-core server it does indeed find Bg5. There is a lot more to this story, and I think the above needs a bit of debunking. …because modern engines at the time such as Stockfish 8 simply could never find it….

Keep a note on quality and total analysis time.News Puzzles Games Strategy Twitch Other Resources Now do some comparisons with sf14_5sec vs sf14_5sec_depth20 and sf14_depth20 vs sf14_5sec_depth20. If sf14_5sec will beat sf14_depth20 in a match of 100 or so games and step 2 is lower than step 1 then sf14_5sec would be a candidate for a good setting. I guess sf14_5sec will win over sf14_depth20, but you have to test this on that hardware. Step 1 and 2 compare the total analysis time while step 3 compares the analysis quality. Run an engine vs engine match, sf14_depth20 vs sf14_5sec.
Analyze game1 (more games and get the average) at movetime of 5 sec, remember the total time.Analyze game1 (more games and get the average) with depth 20, remember the total time.It is a matter of analysis quality you want and the total time to finish the analysis. In ending phase reaching depth 20 is very fast as there are less pieces to evaluate while in the opening phase reaching depth 20 could be a challenge and movetimesec of 5 might be consumed first, depends on your hardware. If analysis time of 5 sec is reached first before depth 20 then the search is also aborted. In this case, when the engine reaches depth 20 before the time limit of 5 sec, then the search is aborted. engine = _uci(stockfish)ĭef evaluate_game(game, engine, limit=(time=movetimesec, depth=depth)): To use both depth and time you can use the following. To control analysis time use the following example.ĭef evaluate_game(game, engine, limit=(time=movetimesec)): The question is what analysis quality are you up to? To minimize processing time you can adjust the depth or movetime or both. The link refers to stockfish 11 and you are now using stockfish 14, so that article is irrelevant. Info = engine.analyse(board, limit=limit)
#STOCKFISH 15 ANALYSIS BOARD CODE#
I haven't modified any Stockfish settings since installing. ** **I am using a virtual machine with 32 vCPUs and 64GB RAM but processing is slow (though htop claims it is using 99% of CPU%). It calls Stockfish 14 to analyze each game at depth 20. I am running a python script that analyzes a large batch of PGN games (each of ~5,000 games) across and exports the games evaluations.
