A pawn island is a cluster of one side's pawns on neighboring files, separated from that side's other pawns by a file without any of its pawns. A pawn island is a cluster of one side's pawns on neighboring files, separated from that side's other pawns by a file without any of its pawns, and fewer islands usually signal a healthier structure. To count islands, look at one side's pawns file by file and start a new group wherever a file holds none of them. With pawns on the a, b, d, g and h files you have three islands: a and b, d alone, and g and h. [Doubled pawns](https://georgelichess.com/glossary/doubled-pawns.md) do not add islands, since two pawns on the same file still sit in one group. Why does the count matter? Inside a group, pawns can guard one another, but the pawn at the back of each group has nobody behind it, so pieces have to look after it. Every extra island therefore creates another pawn that needs piece protection, and a group of one is an [isolated pawn](https://georgelichess.com/glossary/isolated-pawn.md). In the [endgame](https://georgelichess.com/glossary/endgame.md), when few pieces are left to do that job, the side with more islands is the one under strain. The count is a guide, not a verdict. [Active pieces](https://georgelichess.com/glossary/piece-activity.md), a safe king or a [lead in development](https://georgelichess.com/glossary/lead-in-development.md) can outweigh a worse structure in the middlegame. To improve your own count, trade off a lone pawn or link two groups by advancing a pawn between them. Against the opponent's islands, look for the separated groups and aim at the pawn that has the fewest defenders. ## Example position White has three pawn islands: a2 and b2, then d4, then g2 and h2. Black has two: a7, b7 and c7, then f7, g7 and h7.
