I'm not sure what a PA is. Anyways, an xy-wing and a UR1 do this up nicely.

As I get bored and alter the constraints on my puzzle generator, I give a set name to the puzzles generated. The "A" subset identifier indicates that this set didn't produce many interesting puzzles ... and I may generate a "B" subset to see if this was just a one-time case.

As for the NNP and NNP_2 sets, they where originally named Keith because of the constraints he suggested; but he seemed embarrassed at having the sets named after him, so I change them to No Name Please. Laughing

BTW, I never did get keith's constraints to work very well. My puzzle generator definitely has its limitations!
