				Hobby,
 
 
  I've never heard of 'pattern rule method F'.  From where did you hear the term? |

				I came across "Pattern Rule Method F" when using this page to solve a puzzle:

I don't know what it means, either.

				Essentially what the solver writer has done is to categorise solving techniques with his own scheme.
 
 
His "pattern F" is using X-Wings(F2) and swordfish(F3). |
