Reckless 0.9.0 claimed first place in the Kingmakers' Revolt round-robin, a brutal eight-engine tournament spanning 80 rounds with 560 total games. The engine finished with 311.5 points and a 55.6% score, narrowly edging PlentyChess 8.0.0, which scored 300.5 points despite starting with a higher rating advantage of 2872.0 to Reckless's 2863.0.
The tournament reveals shifting engine hierarchies. Reckless actually lost six rating points from start to finish (2863 to 2857), yet still dominated. PlentyChess dropped 24.2 points, suggesting it underperformed its opening expectations. Alexandria 9.0.0 impressed by gaining 10.8 points while climbing to third place, posting a 52.8% score. Pawnocchio 2.0.1 and Berserk 14.0 followed further back.
These engine tournaments matter for the computer chess community because they track real performance gaps across hardware configurations and optimization levels. The five-percent handicaps applied to each engine level the field artificially, forcing stronger engines to play deliberately constrained versions. Results like these highlight which engines maintain dominance under pressure and which fall away over long matches.
Reckless's consistency across 560 games against top-tier competition cements its standing, though the modest rating loss suggests the competition was fierce enough to prevent any engine from running away decisively.
