LittleWing -  XBoard and UCI communication protocols author - Vincent Ollivier github: https://github.com/vinc/littlewing Rating Chess Engines Diary CEDR=2540 LittleWing - what's new?

Fixed Fix insertion sort in movegen (#143) Do check before search in root (#131) Fix internal iterative deepening (#130) Fix UCI issue with PV after draw (#112) Fix invalid claim (#103) Fix std (#100) Fix clippy warnings (#99) Added Add TT prefetch (#145) Add check extension (#142) Add history heuristic (#128) Add improving heuristic (#139) Add libm to compute log in no_std (#146) Add noisy/quiet moves (#144) Add reverse futility pruning (#135) Add tempo to eval (#127) Add a...
