numbering the boxes and positions in the boxes as follows:

The following ALS-XZ moves are next needed to solve the puzzle:

r1.26 =47= r2.27 {9} r1c8
r1.26 =47= r2.27 {9} r1c9
r1.26 =47= r2.27 {9} r2c8
r1.26 =47= r2.27 {9} r2c9

r1.2345689 =67= r2.2356789 {3} r1c1
r1.2345689 =67= r2.2356789 {3} r2c1
r1.2345689 =67= r2.2356789 {3} r2c8
r1.2345689 =67= r2.2356789 {3} r2c9
r1.2345689 =67= r2.2356789 {3} r4c5
r1.2345689 =67= r2.2356789 {3} r4c9
r1.2345689 =67= r2.2356789 {3} r5c8
r1.2345689 =67= r2.2356789 {8} r1c1
r1.2345689 =67= r2.2356789 {8} r2c1

r5.489 -6- r8.46 {3} r5c5 // als xz move with the two sets linked with one restrictive common candidate -6-
r7.123578 -4- c8.12569 {9} r7c9
r7.123579 -4- c9.1245 {9} r4c7

Code:

```67 ``49 `2568 2568 ``26 79  ``1 2348 3458

now singles are enough to solve
