Opening fingerprints
See the lines they return to under pressure, where they leave book, and which sideline pulls them into unfamiliar territory fastest.
Tournament prep, distilled
Know the player before you meet the position.
PrepDeck turns a Chess.com or Lichess username into a focused opponent dossier: openings they trust, positions they mishandle, time-pressure habits, and drills for the game you are actually about to play.

The unfair advantage is preparation
Not an opening trainer. A scouting report for the person across the board.
Generic prep tells you what is theoretically best. PrepDeck shows what this opponent actually plays, where their confidence lives, and where the game tends to slip away from them.
Human weakness map
PrepDeck looks for repeated mistakes across real games: pawn structures, endgames, tactics, clock habits, and rating-pressure patterns.
Drills for this opponent
The coach asks you to think before it explains, so the prep becomes practical rehearsal instead of a passive engine dump.
Inside a dossier
A calmer way to walk into a serious game.
PrepDeck is built for the player who wants the quiet confidence of having done the work: the anti-repertoire, the psychological read, and the small practical reminders that matter on move thirty.
