Chess engine: Esox (Stockfish derivatives) by Solista engine from page: https://solistachess.jimdosite.com/solista-news/ From the author:  Esox II - This version is slightly faster in its search, with significantly less aggressiveness on zero moves, which I prefer for analysis. This version even outperforms the StockfishMZ 121225 reference by at least 2m + 0.1s in the Bullet and Ponder ON charts. Esox II download

Chess engine: Esox (Stockfish derivatives) by Solista engine from page: https://solistachess.jimdosite.com/solista-news/ From the author: For this version, I've combined the best code from the SF Developers, M.Z., and I.Ivec, and the CorChess code is implemented 1:1. I've also implemented features that I consider essential. These include Slow Mover and Minimum Thinking Time for playing, as well as support for the PolyGlot book. For analysis, it's important to me that the calculated move is displayed much earlier, not after more than 30 seconds; I've chosen 5 seconds. This latest engine of mine is called Esox . It's similarly strong to StockfishMZ 121225 (tested) for blitz games of 5 minutes or more, and it's universally applicable for analysis (also tested). Esox download
