Editing Rules of Go (section)

=== Board sizes ===
Most [[Go (board game)|Go]] is played on a {{nowrap|19 × 19}} board, but {{nowrap|13 × 13}} and {{nowrap|9 × 9}} are also popular sizes. [[History of Go|Historically]] other board sizes were commonly used (notably {{nowrap|17 × 17}}, a predecessor of the {{nowrap|19 × 19}} board in ancient China). Go is also sometimes played on various ''novelty'' sized boards as small as {{nowrap|5 × 5}} and larger than {{nowrap|19 × 19}}. All board sizes have an odd number of lines to ensure that there is a center point, possibly to make [[mirror Go]] a less attractive strategy. Generally all rules apply to all board sizes, with the exception of handicaps and compensation (whose placement and values vary according to board size).
