Read your opponent
before move one.
Every player leaks patterns — a narrow repertoire, a clock that runs dry, a slide after the first loss. We read them out of their public games and hand you the lines to play.

How it works
01
Name the opponent
Any public Chess.com or Lichess handle — nothing to connect or link on their end.
02
We read their games
Up to two years of history — openings, clock habits, and how they behave after a loss.
03
Play the lines that hurt
Prep against their actual repertoire, plus a practice bot that mimics them.
