My wife and my bosses keep the white men away
To avoid remembering digits or 3-way solutions (which often are preferred by manual solvers, when they are easier to spot and read) you have to use tricky AIC links here.
Steve has found a good one, (9=2468)b8p1479 - (2|4|6=13)b5p45, which is easy to verify.
My solution was somewhat artificial, though logically correct.

(9=6)b8p1479-(6=1|3)r4c6-(137=2|4)r245c4-(248=9)r789c4 => -9r6c4, stte
The link (1|3)r4c6-(137=2|4)r245c4 has to be checked:
The 3 can only be in r4c4, and if -1r45c4, you cannot have 37 there. So there must be a 2 or 4 in the 3 cells.
The other way round:
248r789c4-(2|4=137)r245c4 including 13r45c4 is easier to see, because 1, then 7 and 3 fall into place.
