An ALS XZ solution: either 9 is true at r8c5 or r3c6:

(9=1)r8c59 - (1=9)r3c169: => r9c6 <> 9; stte

btw, this can also be expressed as an xyt chain: (9=5)r8c5 - (5=1)r8c9 - (1=2)r3c9 - (2=5)r3c1 - (2,5=9)r3c6. (Not sure of syntax)

(9)r9c5 = (9-1)r8c7 = (13-9)AHS:r3c37 = (9)r3c6 => r9c6 <> 9
or
(9=5)r8c5 - (5=1)r8c9 - (1=2)r3c9 - (25=9)ANS:r3c16 => r9c6 <> 9

There is no weak link between (5)r8c5 & (256)r2c45,r3c6 as both can be true simultaneously.
