The Q can move along the b-file.
The R can move along the 3rd rank.

As they can.

To RJ's Rb3 - Qa5#
To Qb3 - Qh1#

any other movement by R along 3rd rank and Q along B file means that either b6 or e3 is unprotected, allowing the knight to mate.

My bad. Qa8#
I think Qa8 and Qh1# work whenever the R and Q move...
