Ed, would you like the XY chain or the ALS
(9=3)-r6c8-(3=7)-r8c8-(7=1)-r2c2-(1=5)-r2c3-(5=9)-r3c1 -> r6c1<>9
ALS(A=[r68c8],
, X=7, Z=9) -> [r6c1]<>9

The chain thanks - more Christmassie.
OK, my turn - then back to mutilating more presents by 'wrapping' them.
1 in r9c9 -> 1 in r8c2 -> no 1 in r5c2
1 in r2c2 -> no 1 in r5c2
-> no 1 in r5c2

Strong links on 3s -> r4c1<>3
then
ALS(A=[r46c1], B=[r26c3], X=3, Z=5 -> [r3c1]<>5

I was just practising a little on the x-files. Also did this one and thought i just share a little.
There's an easier way to crack the puzzle

Take this UR. 69 locked in R1C45, 9 locked in R8C45 which eliminates 6 from R8C45. This gives you the 6 in R8C1 and the 7 in R7C1. this gives you a naked pair 18 in R57C9 and the puzzle falls.
