[Retros] last move type DD/ PxN=N

[raosorio at fibertel.com.ar]

Dear Mario,

"A typo or did you just overlook this?"

I'm affraid it's the 2nd. We were confident with the locking (no PxR=N) but we didn't check
the capture balance properly.

trying to rework it.

Rgds,
Roberto

As given, both black and white pawns must have made 4 captures - so 
all missing pieces, including wRa1 and bRh8 were captured by pawns. 
Therefore, last move cannot have been PxN=N, but PxR=N. 

But after uncapturing a rook on g8/b1 thze black/white king is 
locked and can never leave his prison. 

A typo or did you just overlook this?
