Drill the 22 decisions that matter

This is the board-work section. The 22 drills cover book moves, plans, traps, punishments, structure, and endgame echoes. Solve from the position, not from the move list: each answer has a concrete reason, a wrong move is marked briefly, and the two-stage help gives a board cue before highlighting the piece.

Play the bot and apply it

Now play it out. Pick a Petrov variation, choose a bot strength, and start from the position that matters. The coach watches for guide patterns, including the early recapture trap, the Classical c4 break, and the Nimzowitsch king race.
