[Retros] Messigny-Retros: "Ready-Made"

[Mark Thornton]

I fear that it is too much to hope for, as it is very hard to see how the 
White moves 1.e4 2.Sf3 3.d4 could be made to have a unique move order.

Best wishes
Mark

Ah -- I was hoping that "accelerated" hinted that a position
(in the Dragon but possibly not the Accelerated Dragon) that is
usually reached in N moves has a proof game in fewer than N !
Is that too much to hope for?...
