Proposed Variant: GoMove

[freact]

Rules are as in go but:

On your turn you may, in addition to your regular stone placement, "move" one of your stones from its current position to an empty adjacent intersection. The move is optional and can be played before or after the placement.

I think there's some other details to work out. Like when captures should be evaluated, or whether the stone placement should be optional too (allowing a turn where you only move a stone and don't place one). Whatever is easiest to implement is probably fine for these though!
