Where to start

No two clues on puzzle #40 pin down a single route between them, so there is no forced opening to hand you. With 17 clues over 64 cells and a gap of up to 7 numbers, start from the tightest cluster of clues and work outwards — the corners and edges of the board are where your options are narrowest.
