Steve,

It's been quite a while since I've played an ER, but I think something's wrong, but I can't explain why. If it's an ER on 3, it's also an ER on 9. So we'd have r9c6<>both 3 and 9? But it's bothering me that I can't back up my statement, so I'm not fully confident.

[SteveG48]

Marty, it's an ER on 3's because of the strong link on 3's in c9. There's no similar link for 9's.

OK, I didn't notice c9 and was assuming the SL was in b8 and I think I forgot the rules of an ER.
