Well, I still think mirroring is a bit easier on even size boards (you can't just play tengen to break it). But sure, even size boards are playable.
Perhaps it's simplicity? In terms of complexity per intersection odd-size square boards are simplest, followed by even size square boards, and then the rectangular boards. 1xn Go is hell :-) Erik On Mon, Jan 7, 2013 at 3:23 PM, Don Dailey <[email protected]> wrote: > So really then even size boards are perfectly playable.
