You often know which row someone is in long before you know which square. The margin beside each row and column is a claim target: select a suspect, press the margin, and that row is theirs.
The board answers the moment you do it. Everyone else loses that row; everything the claim rules out for the people the testimony speaks about shades itself. It is the fastest way to turn a half-deduction into visible progress without committing to a square you cannot justify.
