XY-Wing 459 at r6c8

XY-wing pivot r4c8 or r7c8 solves it.

XY-wing 268 => r8c1 = 1 which solves it.

XY wing, pivot r2c3 => r2c1 <> 6

Several XY-wings. Found a one-stepper: 239, pivot r1c2 => r45c3<>9. May be there are others!

An obvious UR15 gives r8c1=6 or
an XY-wing 269 gives r9c3=9

XY-wing 156, pivot r5c4, solves it.

XY-wing 125, pivot r4c4, makes it.

One more basic move: r1c6 = 5. For those who accept UR:s, the UR39 then gives a very simple solution!

I needed no advanced technique at all! Am I right?

One stepper: XY-wing 459, pivot r9c2, gives r2c2 = 4.

XY 158 gives r4c7=2.

Another one-stepper: XY-wing 289 gives r8c7<>9, which is enough.

At least two XY-wings 349 solves it.

The usual: x-wing 379, pivot r4c2, gives r3c3=3, which solves it.

The XY-Wing 247, pivot r7c4, solves it in one step.

An XY-wing 158 forces r7c9=8, which solves it.

XY-wing 169, pivot r9c3, forces r9c2<>9, which solves it.

The XY 136, pivot r4c8, gives r5c3=2, which solves it.

I used the nearby 457 X-wing leading to r7c9<>7.
