◇ Just read — no move neededSharper waters
The engine at strength 4 punishes loose moves: an unrooted piece left on an open file, a pawn grabbed while your palace gate stands open. Before every capture and every trade, ask the questions the tactics chapter taught: is the target rooted, and what does the board look like one move after the material lands? If you cannot answer, improve your worst-placed piece instead — the safest improving move is the one that adds a defender to your weakest point. Complete 24 of your moves to finish.
