The C4Chess prep lab
Most players guess. You'll know.
Scout your next opponent from their real games, rehearse against their own repertoire, then sit down with a plan already written. Included with every C4Chess account.
Every stat is confidence-gated. Nothing is shown until the sample is big enough to trust.
01ScoutRead hundreds of their recent games.
02SparRehearse against their repertoire.
03PlaySit down already knowing the plan.
FlagshipFirst report free, no account needed
Scout
Know their game before move one.
Drop in any chess.com or Lichess username. C4Chess reads their real games and hands back a dossier: which openings they fall apart against, when their clock starts bleeding, and how they play right after a loss.

Spar
Play them before you play them.
The bot answers with their moves, at the frequency they actually play them, and follows your transpositions. Take them out of book and it keeps going at their measured strength and their error rate.

Daily lessons keep the habit alive, and parents always know what their child is working on.
