Hello Mark,
I don't think Rg6 is a mistake.  Hiarcs 7.32 locks on to Rg6 instantly and never
lets go of this move.  At the 5 minute mark it has a score of -1.21 with a
continuation of 1...Rg6 2.Rg1 Re8 3. Qd3 c5 4. f3 c4 5. Qc3 Qg3 6. Be6 Qf4.
This may all be fantasy but it's interesting to note that c5 was in the plans of
Hiarcs  also, just later on. It's also interesting to note that Bxg2+ was 2nd on
the move list of Hiarcs.  So the computers were strongly considering the Bishop
sac here.  The move c5 was number 5 on the list.
