OK, that is what I thought. But for one, a single game is hardly statistically significant, and even in 10 games you can only draw a (weak) conclusion from a result like 10-0 or 9-1. But if the engine used is excessively weak, even that would be meaningless. Fairy-Stockfish is not automatically strong in every variant you configure it for, just because Stockfish is strong at orthodox Chess. It might have a world-class search, but strength depends on evaluation as well as search. With faulty evaluation good search only backfires, as the engine gets more clever in finding ways to force losing trades, or create trouble for itself in other ways. And the heavy pruning makes it blind for the lines that are actually winning, as it considers those poor play, and thus irrelevant.
QueeNy uses piece values Q=9.5 and N=5, which is not optimal with fewer Knights (where de Q/N ratio quickly goes up), but good enough to avoid getting there. But even then, to effectively clobber Stockfish required removal of the normal King Safety evolution. It could even beat Stockfish and many other top engines of those days with 6N vs 3Q (which is theoretically lost). The top engines never took the opportunity for making a 1-for-2 trade, (the first step for whie towards the win) until it was too late, and they had to sac 1-for-1.
