[Retros] Massacre proofgames

[Mario Richter]

I'd like to repeat Andrew's question: Do you have a source for
your claim?

As far as I know, only MPGs up to 35/5 have been completely
analyzed.

Chances, that a uniquely realizable MPG with 36/6 exists, are
very low - but I thought, that the definitive answer to that
question still has to be found ...

Best,
