TABIYA
A tabiya is the position a whole opening is aiming at — the spot both players know they are heading for. Across the table, Kedar plays only 📖 book moves, so you get there every time. Learn them by repetition: master a whole line and it returns later; slip and you'll see it sooner.
Run-through: play a whole opening from move 1.  Spot cards: one book move per card.
