				| Thanks Immpy, a nice puzzle to end the year 
 Sometimes patterns are nice to spot, but may or not help you solve
 
 In this case, you can remove the 1 in r7c1 as you would get <46> pair in box 7 and then also r7c9=2, r5c9=9 gives <46> pair in box 4 creating UR
 
 This led me to say if r6c1=9, r6c7=3, r4c9=9 leads to no <9> in box 5
 
 Happy New Year
 
 Tom

				| Well since 9's are the focus, I will look elsewhere to a nice XY chain. 
 Pincers for 4 at r4c2 and r5c8 means r5c12 < > 4. Follow a-d. Or d-a if you prefer.

				| Extend the XY chain by one and r6c7 <> 4 as then a=4 and no <4> in box 5 |  |

				| Extend it one further still and we get r6c4 < > 4 because if it was then another 4 gets put into r4c4 - two 4’s in box 5.  Contradiction. |  |

				| ….if you insist r6c4 = 4 then r4c4 < > 4. It also means there’s a 9 in r4c9. So r4c4 < > 9
 That 9 created a <26> pair in box 5 and r4c4 < > 2
 
 R4c4 is empty …….. Is that echo Perry Como I can hear ?

 Be a while before she plays Gibraltar again.
 She jumped on the stage there and shouted out:
 “Hello Spain!”.
