Chess coaching deserves better than duct tape

You teach chess - you should not spend evenings reconciling calendars and chasing payments.

Scattered tools

Lessons in Google Calendar, students in a spreadsheet, puzzle PDFs in email threads, and payment status in your head.

Admin after teaching

Chasing unpaid lessons, resending Meet links, following up on homework, and checking who still needs to be scheduled.

Generic tutoring software

Most schedulers ignore the unique rhythm of chess coaching - sparring, separate rates, puzzle homework, and direct payments.

How it works

Get set up in minutes - then run your week from the dashboard.

  1. 1

    Connect Google Calendar

    Sign in with Google - Square64 can create, update, and cancel lessons and sparring on your calendar, and read busy times for conflicts and availability.

  2. 2

    Add students and set availability

    Build your roster with lesson and sparring rates, set working hours, and publish your public profile when ready.

  3. 3

    Schedule and track sessions

    Book lessons, sparring, or weekly series from your calendar. Get Meet links, track payment status, and send branded student emails.

  4. 4

    Assign homework

    Create a themed puzzle set or timed racer sprint, share the student link, and review how they solved - including arrows and circles - before your next session.

Everything you need to run a coaching practice

Find weak themes, review how students solved, assign puzzle sets or timed racers, then run calendar, overview, and your public page from one workflow.

Student analytics

See which puzzle themes each student is weak at, strong at, or has barely practised - then turn that into homework.

Student analytics for Maya Chen with weak puzzle themes and generate homework
Spot weak themes across homework, then generate the next set from the top picks.
  • Per-student theme breakdown - weak, strong, and uncovered motifs across all homework
  • Generate the next set straight from a student’s weak themes

Homework review

Open results for puzzle sets and racers before the next lesson - see thinking on the board, not only right or wrong.

Coach homework analytics with puzzle timeline and board arrows
See how a student thought through the position - marks, wrong tries, and timing.
  • Timeline of marks, wrong tries, and timing per puzzle
  • Board arrows and circles replayed as the student drew them
The part I open after every homework is the analytics. I can see how a student actually thought through the position, not just whether they got it right, so it’s much clearer where their play is weak before the next lesson.

Puzzle sets & timed racers

Two homework modes between lessons - curated puzzle sets or a clocked racer sprint. Preview, swap, then assign via link or email.

Homework puzzle grid with swap controls for a themed set
Build a puzzle set or racer pool - preview positions and swap anything that does not fit.
  • Puzzle sets - mix themes or require all of them on one puzzle, rating band, and quantity; preview and swap
  • Review past mistakes or skip puzzles a student already received
  • Timed racer - a fixed puzzle pool against a global clock
