Computer opponent – here there’s no need for extensive depth since the game is against a human with far inferior calculation capabilities.For the Decoding process – during a single Decode process, our algorithms use Stockfish hundreds of times in various depths, and at the same time allocate substantial CPU efforts to finding the best move.It won the 2018 computer chess championship on and appears on the analysis boards of leading chess websites, including lichess, and more.ĭecodeChess uses Stockfish in several ways, and depth changes from one case to another: What Chess Engine is Being Explained by DecodeChess?ĭecodeChess explains the moves of Stockfish, which is considered to be one of the top chess engines in the world. The number of variants that were requested.The engine itself (Stockfish, Houdini, Komodo, etc.).The amount of time allocated for the analysis. The strength of the computer on which the engine is running.The type of chess position in hand – the more good options (for example opening), the lesser the depth.But it doesn’t mean that all possible 18-ply variations are being checked, and thus there may be cases (though not frequently) that the chess engine will miss a good variation. However, other factors come into play here and they are too technical for the purpose of this article.įor example, (+0.77 depth 18) means white is up 77 centipawns after calculating 18 plies ahead. Generally speaking, we can say that the greater the depth, the more accurate the score and the prediction. What is Depth and Should I be Worried About it?ĭepth indicates how many plies ahead in the game the chess engine was able to “see”, withĪ ply being is a move made by one opponent (B/W).
