One of {r1c23,r23c1} contains 2 (out of 3) of the digits {6,7,8}.
If it's r1c23, then 2r1c6 and 1r1c9 are forced.
If it's r23c1, then 2c1c6 and 1r9c1 are forced.
Either way, 1r9c9 must be false ... stte.

Alternatively: (1=(4|8))r1c9 - 4678r1c2348 = (1&2)(r1c23,r3c3) - ((1|2)=5678)r2348c1 - ((5|6|7)=1)r9c1 => -1r9c9, stte.

(1)(12)(c1r1 / r69 c69 + b1) = (1)(b1p2347) - (1=2)r3c3) -(2) r1c3|r3c1 = r1c6|r6c1 - (1)(r6c1|r1c6 = [c1r1/ r9c9+b1] ) :=> r9c1 <> 1

the idea is that 12 multi fish exists eliminating r9c1 <>1
or the box 1 contains 1 some where meaning r3c3 is a 2, which removes 2 from box 1 setting r1c6,r6c1 as "2" which reduces c1r9 regardless of where "1" is in box 1 as a 2 string kite eliminating r9c1 <> 1

unless some else has a better description of this
Some do, some teach, the rest look it up.
