With the Unique openings, the draw rate is over 92%deeds wrote: ↑Thu May 01, 2025 8:45 amAt SedatChess, engines obtain the same statistics under different conditions !![]()
Exemple with Stockfish 020425 (7 elo / 8 elo, 51.1% / 51.0%) :
And it was the same lottery for Omega MPV (6 elo / 6 elo, 50.8% / 51.0%), Artemis 12TR (-3 elo / -2 elo, 49.5% / 49.7%)...

To know which engine is the strongest in general, we have to cover as many ECO codes as possible and avoid non-discriminating positions (like the starting position, drawish opening lists, heavy unbalanced positions, positions with poor mobility of pieces, etc.)botunnet wrote: ↑Thu May 01, 2025 1:55 pmWith the Unique openings, the draw rate is over 92%only 372 games (=8% of 4680 games) are useful for separating engines
we just learn which engines blunder the most due to lack of time in drawish positions
it's only an useless lottery.
With the UHO openings, the draw rate is barely 56%2055 games (=44% of 4680 games) are useful for separating engines
we learn which engine knows how to capitalize on an advantage, which engine resists under pressure on non-drawish positions, which openings should be trained, etc.
