P.S.  I doubt any engine will find Rc6 either.  I really don't think it's the
best move...maybe second best, I don't know.  White's play doesn't end with 1.
Nc3.  He has the open file, a lead in development (and a better development),
and finally, black's queenside pawns may be vulnerable.  I think 1. Nc3 is the
way to go.
