Task 1 — the long chain. Row 7 carries a pair at (5,7)–(6,7); column pairs wait at (4,6)/(4,8) and (8,6)/(8,8); row 9 hides another pair at (5,9)/(6,9); and white's two caps (8,4) and (8,10) make sure the column can only ever four through the middle. Five black stones are coming, every one of them a threat. Start: grow the row toward your columns.
Solve the remaining tasks to finish this lesson.
