Sparring · Opening training
Train your openings. Find your move.
Choose your training material and play on the board. Chessparring follows the branches of your prepared variations without revealing which will appear next.

Replies come from the variations you have prepared. You find your move in each position.
- Select collections, openings, or lines to decide what goes into your session.
- Get feedback on your moves, use a hint, or reveal a move when you need help.
- During training, mark difficult positions for Review and return to them later to study them again.
