[Retros] Add pieces update

[Kevin Begley]

Hi Alain,
Here's an easy way to achieve N1CQ:

fen: 1nbqk3/5ppp/4p1nr/8/7K/5P2/PPPPP1PP/1N4N1
Add 1 unit.

Have I missed something, or is +wQh5 not the only solution?
I suspect there must be a more economical realization, but it's not
immediately obvious to me.

Best Regards,
Kevin
