Move History & Analysis

Based on stebansaa's llm-chess-arena

Moved all ressources local, fixed up UI and a bunch of bugs (providers, reason order, temprange, PGN, autoplay) and added more features such as sound, last-move highlights and automatic material calculations.

I ran a 15-model tournament and documented the results, which you can view here: dubesor.de/chess/tournament
