Being the extraordinary cheapskates *cough* multi-taskers we are, the Chinese have developed a bevy of games utilizing a wei chi set.

 

One such game is Connect Five, in which (like it sounds) black and white take turns laying down pieces until one player has a line of five pieces (horizontal, vertical, or diagonal) and wins. 

 

Assuming both players are actually trying to win, what is the maximum size (square) board on which the game could end in a tie?

Yeah, the game is one that can be and to some degree has been 'solved' in terms of forcing sequences, the question can be alternatively asked what is the minimum forcing sequence?
