Lots of possible moves with this puzzle; I used two steps.

Quote:

xy-wing 36-9 with vertex 36 in r6c1, pincer 69 in r4c2 and pincer 39 a pseudocell in row7; r4c9<>9,
useless xy-wing 3-69 with vertex 39 in r8c3; no direct deletions, but transport 6 in row r9c2 to r5c6 to delete 6 in r8c6 to complete the puzzle

I also used two steps sandwiched between basic moves:

Quote:

(3)r3c4=(3-6)r8c4=(6)r8c6-(6=3)r5c6-(3)r6c5=(3)r6c1-(3)r7c1=(3)r7c5 => r3c5,r8c4<>3

(6=9)r1c6-(9=3)r8c6-(3=9)r8c3-(9=5)r6c3-(5=2)r6c4-(2=9)r6c8-(9=6)r3c8 => r1c79,r3c5<>6
