Above is a puzzle I ran through the Scanraid Solver and came up with this AIC.

Scanraid says:

"AIC Rule 2, on 8 (AIC , length 6:

7[H2] =7[D2] -7[F1] =8[F1] -8[E3] =8[H3]-

-Chain ends H2 cannot be 8 and H3 cannot be 7"

I can follow what is going on in that if either D2 or H2 (strong links) =7 that D2 must equal 9 and F1 must equal 7. That is as far as I can go and I do not understand the logic that make E3 = 3.

I don't understand the notation that Scanraid used to describe the AIC.

Perhaps there is a different notation that would explain this to me in a way that I could understand. Or, barring that, somebody could explain just how to go about understanding the notation used by Scanraid. Any help or comments will be appreciated.

Either way, many thanks to the members that have always come to my rescue.
