[Retros] last move type D, DR and O-O/P- case

[raosorio at fibertel.com.ar]

Hi Mario,

There is some polemics regarding the DR nature. Orthodox? Fairy?
Applied to Last Move Type D records, the only case presently under this
"conflict" is the O-O/P- one, compossed by Lois and me with 18 pieces
based on DR, while the non DR version needs 20 pieces.

This situation would be solved if the following position is correct,

O-O/P-/18      8/8/8/8/4P1P1/2PPkpPB/1PrR1RPr/2BQ1RK1

Best,
Roberto
