Relative Coordinates

This is a coordinate system adapted from Go that allows us to talk about important moves in the same way, regardless of board size. We use YX instead of XY because row is more important in Hex, and because we're taking the bottom red edge as our perspective, as is customary. This also most closely resembles how people talk about certain moves already. 4-4 becomes 44. 5-4 becomes 54'.

44

54'

5'4

4'4'

We don't always have to use the smallest number if the reference point for the move is on a different half of the board. Here, stone A could be labeled as 62, but it would be preferable to label it as 8'2 when talking about it in the context of the other two stones, as this is a common opening sequence. Labeling it as 8'2 insures that that pattern is always labeled the same regardless of board size.
