Re "Using thickness, part 2" [#753]
While I understand the point you're trying to make, in the diagram "Using thickness, part 2", it's not really clear (and especially wouldn't be for a beginner) why 
is possible now, but 'wouldn't' be possible without the wall at the top of the board. (And if there isn't this distinction to be made - i.e. if it would or wouldn't work regardless - then the value of the wall simply isn't illustrated.)
Thanks. I'll try and figure out a better way to phrase that. Sorry, but I didn't see your comment until just now.
is possible, even without the wall at the top. sandwiches the marked weak white group against the black group on the lefthand side.
I think I'm just trying to show that it's wrong to just try and make territory with the wall. I'll have to think about this more.
Thanks for the input.
