Drill the 23 decisions that matter

The 23 boards cover the 5...a6 tabiya, both central structures, the queen fork on b6, the Poisoned Pawn escape, long-castling races, the Sozin diagonal, the ...d5 break, and the f4 queen trade. Every Learn route owns at least two drills, and all five published tests retain their exact setup and answer.
