Pretty much the same:

Code: Select all: 36 5 367 | 1468 1478 1678 | 9 2 16 46 8 b467 | 2 9 167 |a17 3 5 1 9 2 | 3 5 67 | 47 46 8 ---------------------+----------------------+--------------------- 59 137 138 | 18 6 4 | 35 79 2 59 1346 13468 | 7 18 2 | 35 469 469 2 467 b46 | 5 3 9 | 8 1 467 ---------------------+----------------------+--------------------- 7 146 5 | 1468 148 3 | 2 489 149 468 2 b146 | 9 1478 1678 | 4-1 5 3 348 134 9 | 148 2 5 | 6 478 147

ALS XZ: X=7; Z=1: (1=7) r2c7 - (7=461) r268c3 => -1 r8c7; stte

Alternatively, (6=1) r1c9 - (1=467) r2c137 => -6 r1c1, r1c3; lclste

1r2c7=1r2c6-(1=7)r2c7-(7=461)r268c3 => r8c7<>1

Another view is (1=7)r862c3-(7=1)r2c7 => r8c7<>1

After looking at the other two posts, I had to find an alternate solution and a favorite immediately appeared.
