Flash + Chess

Flashess is a chess training platform for opening preparation and tactical sharpness

In Training Mode you practice curated exercise sets with real-time move validation, random mode, vision & hint tools, auto-start opening moves and a mistake review panel

In Creation Mode you import PGNs (e.g. from Lichess), use the opening tree and vision tools to analyze positions and turn them into custom exercises stored locally and optionally synced to the cloud
