  CorChess   is a clone of Stockfish maintained for better performance on long time controls, trying at least partially to fill the gap between regular tests and demands of correspondence players. 👍The Chess Engines Diary team recommends this engine for analyzing chess games and particularly complex positions.

The latest SF-PRO 25042024 engine (which is only available to our testers) won a large tournament of very powerful chess engines. Four engines are just half a point behind it: SF PB 240424, Big-SF 210324 , HypnoS 030424 and Yuliirma 4.0 . How strong the current chess engines are is demonstrated by the Critter 1.6a result, which achieved only one result out of 56 games. 🕓 Time 3'+3" 💻HP Pavilion i5-1035G1 8GB RAM 🖬 GUI-Banksia All  CEDR  333.448 games download  (01.05.2024 - 3'+3")    💾  812 (!) games from the tournament download   👍 @chessenginesdiary  Country - Poland, City -  Malbork Tech table: Engine KN/move NPS dep/mov time/mov mov/game time/game fails AbbyStein v2.8 1744 379894 35.4 4.6 65.6 301.4 Alexandria 6.1.0 2808 552186 29.3 5.1 72.2 366.9 Arasan 24.2.2 3247 496457 26.2 6.5 48.6 317.6 Big-SF 210324 1714 306232 27.6 5.6 61.3 343.0 Blue Marlin 15.7 3338 598824 32.8 5.6 62.8 350.2 Caissa 1.18 4716 884763 28.9 5.3 66.6 354.7 Clov
