prty obvious whats the point to it

 It should be obvious. Glad you found it so. Now, we can get into a further discussion of what makes one puzzle obvious and what makes another puzzle difficult???

Obvious is a relative term. Some people seem to think that unless it's challenging to them it shouldn't be posted..

 Well those people should be out swimming with the sharks and bobbing for apples in an alligator lake! or wrestling with bears in a remote Russian province.

But now...back to the obvious question.

What is obvious? What is not obvious? You bring up the excellent point that obvious is a relative term. Obviously we all know how the pieces move. We when does it start to become not obvious what to do?

Perhaps the options start to compete for attention.
