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.

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.

Why families choose C4Chess for online chess coaching
Chess improvement happens when students practise the right things in the right order — not when they solve random puzzles or watch unconnected videos. C4Chess builds a personalised learning track for every student: structured opening theory, pattern recognition, tactical training, and endgame fundamentals, all sequenced by a coach who knows the student's game. Daily lessons keep the habit alive, and parents always know what their child is working on.
Students who join C4Chess range from complete beginners to competitive club players. Whatever the starting point, the portal gives them a clear next move — and a coach who helps them take it. to see how the programme works, or explore today's lesson to get a feel for the content right now.
For parents: full visibility, zero guesswork
The C4Chess parent portal lets you follow your child's progress without interrupting their learning flow. See what topics have been covered, track session attendance, and read coach notes — all in one place. Chess is one of the best investments you can make in a child's focus, patience, and problem-solving — and C4Chess makes sure that investment is organised, consistent, and measurable.
