Thanks much for the link. That site seems to be unavailable when I follow
the link, so I will have to check back later.
The shogi variant in the referenced photo seems to be played on a 10x10
board with 30 pieces on each side, but the pieces clearly belong to a chu
shogi set both from the distinct types visible in the initial array shown
and the unused pieces in the blurred detail of the upper picture (I think
that I recognize a copper general and a lance).
I suppose that the detail on this blog that first caught my attention was
the name of the variant, which I recognize as one used for a modern chu
shogi variant of Western origin.
