hellochess.cn 国际象棋充电站Stockfish是一款免费开源的UCI国际象棋引擎，源自Glaurung2.1，中文名鳕鱼国际象棋引擎，此引擎获得过顶级国际象棋引擎锦标赛的N次冠军，同时完全开源.引擎具有两个国际象棋评估功能，一个是基于经典评估，另一个是基于高效可更新神经网络的NNUE评估。经典评估在几乎所有CPU体系结构上都能有效运行，而NNUE评估得益于大多数CPU（sse2、avx2、neon或类似）上可用的向量内部函数。
截止20220516，目前最新的版本是Stockfish 15
Stockfish 15相较于Stockfish 14.1的nnue架构有重大的变化，部分搜索算法的改进受到了Koivisto和Seer的启发。值得一提的是，Koivisto仅用了一年半的时间几乎就达到了仅次于Stockfish，Leela和Dragon的水平。这里是Koivisto的官网：koivisto-chess.com
Stockfish引擎并不是一个完整的国际象棋程序，需要一个与UCI兼容的GUI（例如XBoard与PolyGlot，Scid，CuteChess，eboard，Arena，Sigma Chess，Shredder，Chess Partner或Fritz）
