I am looking for good and chess engine for endgame but unfortunately when I test engine with competitive chess players in online,it fails with calculation ability. Please recommend apart from fish family chess engines.Please note I have made ground search in google. thanks for your time
Current top engines almost have no problems with endgames, with the exception of some fortresses, so either one of the best 3 will do just fine. Years ago it was possible to beat top chess engines even in simple pawn endgames, but not anymore. Tablebases improve engine play with a small amount of elos, depending on time control and the set used. 5-men would add +5-15 elos, 6-men up to 30, so this is still something, but nothing to marvel at. 7-men would do fine job, but still only commercially available.
