How this board opens
A first sweep of the overlap rule down the rows and across the columns settles 11 of the 25 cells, about 44%, which is enough of a skeleton to work outwards from. The most generous opening is column 3, which gives up 4 cells on its own. Straight line logic carries it to 17 cells and then stalls, so the last 8 need cross-referencing between a row and a column that share a cell. The finished picture fills 11 cells, and one run in the clues is 4 long — near enough the full span of a line that it fixes itself the moment you reach it.
