[Retros] Pawn to-the-8th-rank mates

[andrew buchanan]

Hi Hirokaz,

Thanks for all your work. I think these last two can both be sharpened
as:

rnbqk1R1/pppppp2/8/5npp/7P/8/PPPPPP2/RNBQKBNR
SPG 6.5
(& similarly with Qg8)

rnbqkbnr/pppp1ppp/8/6B1/8/3P4/PPP1P1PP/RNK1qBNR
SPG 5.0

At least the second is sufficiently short to fall within Francois
Labelle's kingdom, and he could probably compute the minimal examples
already.

Cheers,
Andrew.
