Judge Mike Prcic 01/2020:
The technique in well-known, but the two switchbacks by the white Rook are refreshing.

Grimshaw (black)
Play on the same square (B2, 2) (2022-07-08)
Kabe Moen: Thank you for the comment and version of my problem. Your version is very nice and more economical. However, the point of my problem was not to show a regular Grimshaw, but to show a distant Grimshaw. The distant Grimshaw happens when a Rook and Bishop mutually interfere with each other on two different squares (d5 and f5 in this case). The section editor also mentions this in his comments on the originals. (2022-07-13)
