 Re: N x N chessboard with K knights on it. (response to post by Julius1988) | Reply In general the SG number is the smallest SG number that can't be reached from a position. So while you may be able to reach a 2, if you can't also reach a 1 and a 0, then the SG number for the position is zero.Edit: And don't go wasting more forum-breaking techniques. They are a non-renewable resource and must be conserved for misof's next "most minuses" contest.

 Re: N x N chessboard with K knights on it. (response to post by Julius1988) | Reply Just a small request: could you please edit your original post and remove the table tag? It's really irritating to see it the way it is now.Edit: Thanks, dok :D
