Deep Calculation
The deepest puzzles: five forcing moves and beyond. These are pure visualization training: long king hunts and forced sequences where a single miscalculated move throws the whole game away.
How to spot it: stay ruthlessly forcing, picture the target: the mate or the winning material: and walk the only-moves toward it. Calculate the entire line before you touch a piece. This is the muscle that separates strong players from the rest.
