DRAW_LIMIT_MIN_POINTSconstant

The smallest board a length means anything on, in points.

Nine by nine. Below it a game is over long before any share of the board could matter — a 3×3 has nine points and is finished in nine moves, so "half the board" is four, and cutting a game of noughts and crosses short at four moves is not a rule, it is a bug with a setting in front of it. The whole reason for a length is a board big enough that two careful players can fail to resolve it, and that starts here.
