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.

Thanks that really helped.I thought that a unmovable state is indicated by zero.

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
