## Review & study any game with AI
- [Browse & review pro games](https://kifubara.app/games): Search the professional game database (by player, tournament, date, result) and open any game in the interactive AI review board — step through it with live cloud-KataGo evaluation, explore variations, comment on individual moves, and share annotated reviews by link. No install, no GPU.
- [Famous games](https://kifubara.app/famous): Editorially curated landmark games (AlphaGo vs Lee Sedol, the Ear-Reddening Move, Shusaku's games) — open each in the review board for analysis and context.
- Head-to-head rivalry pages: for any two professional players who have met enough times, a page at https://kifubara.app/players/<id>/vs/<id> gives their full record, by-colour breakdown, and every meeting playable with AI analysis (reached as "Key rivalries" from each player's page).

## Explore openings & patterns (pro-game statistics)
- [Opening Explorer](https://kifubara.app/study/explore): Click through opening moves on a live board and see what professionals actually play from each position — move popularity, win rates, trends over time, notable games, filterable by year and player.
- [Pattern Search](https://kifubara.app/study/pattern): Paint any shape (a joseki, a corner enclosure, any local pattern) on the board and find every professional game containing it, with continuation statistics.

## Cloud KataGo for desktop clients (no GPU needed)
