Not To Mention XY-Wing
It is 15 degrees this morning but feels like 8. I am just going to take the computer's word for it. Aren't I curious about what 8 feels like? No I'm not. I have taken up Sudoku and all my curiosity is now used considering the candidates 1 thru 9, times 81. Ok, less than 81. A Sudoku puzzle with 81 blank cells. That would be a very hard one. I am working on one now with 55 blank cells and it is pretty hard. It is safe to say that I have perfected the technique of recognizing single candidates and hidden single candidates but am not as comfortable with recognizing at a glance locked candidates or naked pairs, triples or quads and am a long long way from attempting any X-Wing or Swordfish maneuvers, although am cautiously and optimistically looking forward to the day when I can in the context of any type of maneuver use those terms.
