The solution is straightforward when one notes the hidden pair 1,4 in 5hj and 5fg which leads to a hidden pair 8,9 in 5abc and 6b. I think think this observation would be a result of what I think of as cage comparison.

I am looking forward to the cage comparison documentation. I assume it covers such things as 5 in 2 and 6 in 2 in the same unit, seems very powerful.

If I'm understanding correctly, this strategy is the exact same as Killer Combinations (hard).
Also, the X-Wing strategies and those below it are useless (or at least really rare). Same for KenKen and KenDoku.
