				Yes, I guess this one was a little different. It was a five-stepper, as I tried to see if I could solve it without using the two obvious Type 1 URs.

				I took 6 steps - so I guess at least one was redundant.  Type 1 UR; ER's on 3 and 4, Skyscrapers on 4 and 9; xyz wing on 349.
 
 
What was meant by a "change of pace". |

Well, I thought it was going to be easier for everyone to solve -- only two non-Basic steps necessary.
 
 
 	  | Code: | 	 		     c2b1  Naked  Pair                     <> 49   [r45c2]
 
 r7      Naked  Pair                     <> 49   [r7c1458]
 
 
         UR Type 1 [r13c27]              <> 49   [r1c7]          ***
 
 
 r4      Naked  Triple                   <> 149  [r4c5]
 
   c5    Naked  Pair                     <> 36   [r8c5]
 
     b8  Naked  Triple                   <> 459  [r89c4]
 
 
         Remote Pair   (2x Skyscraper)   <> 49   [r4c1],[r6c4]   ***
 
 
     b6  Naked  Pair                     <> 49   [r5c789]

...yeah but some non-basic steps are more non-basic than others. I'll stick with my 6 step programme. |
