Submit a Course

Suggest an opening for Openings Game to add. Paste one variation per line — every line becomes its own drillable line once the course is built. This goes into a review queue; it isn't published automatically.

One line of moves per variation, move numbers optional (1. e4 e5 or e4 e5 both work). Every move is checked for legality before you can submit — an invalid move will point you at exactly which variation and move needs fixing.
