Chain Segment: ... = 3r3c2 - 3r8c2 = hp(37)r8c78 - ???
It follows that <7> is locked in r8c78 and must have been eliminated elsewhere in [r8] and [b9]. It can't contribute any eliminations from the Hidden Pair.
There is an SL for <3> in [r8], and a simpler chain segment -- ... = 3r3c2 - 3r8c2 = 3r8c78 - 3[b9] -- exists for eliminations of <3> in [b9].
Thus, I'm left with the only realistic eliminations (in the chain) associated with the Hidden Pair being the candidates Y and Z.
Agree/disagree ?
