23 and stuck. It's not going easily for me today.
Well, I finally found something. It was a hypothetical virtual. Now I'm 27 and stuck.
Did it, no green, no guess. I would say that a hypothetical virtual is more difficult than a Medium trick, although once I found it, it wasn't difficult to visualize. I'm going to give that one a 50.
If you're wondering what a hypothetical virtual is, the argument went like this. If this cell is A that that cell must also be A. Between the two of them, they guard against A in a third block except along a line -- a virtual A. The first A and the virtual A together guard against any A in a forth block. Therefore the first cell is not A.
It's like a block pincer, except A is only partially overruled in the third block. I think it may be the first hypothetical virtual I've encountered.
