Breaking News (31.10.2023):

   Well, after bad experience with Banksia tour, I've realized to run with almost   Same conditions exc..as main difference this time via CuteChess 1.3.1 GUI   Plus I switched to 2m+1s (instead of 3m+1s) and what I can say more, here   All stable..after checking...no any buggy game is recorded...just great news!   As final conclusion, definitely some of the engines suffer under Banksia GUI!   And let's hope next Banksia GUI releases to be more stable for game-play...   Note also that during this competition..quite frequent RapTora was leading...   But in last rounds, Stockfish is managed to be Number One...on other hand,   RapTora is old-dated but still not dead...if nothing else under these cond. !   Btw, more info about current tourneys, you can read at: OpenChess forum
    The Champion: Stockfish 231023 - My Congratulations to Stockfish team!
