Fencer, are you thinking about Juggernaut Chess at all ? (as it is almost the same as Behemoth Chess)

I like the idea of the random direction including a 'No Move' and a 'Teleport' selection, as well as the 8 normal directions.

Behemoth is great fun, BUT can be over in 1 move as you mention in your blog.

With the Juggernaut rules at least there is a small chance he may not move sometimes, need to slow the Beastie up somehow lol
