I created a new version of the Interactive Diagram script, which currently is only used by the Tenjiku Shogi diagram to which this is a reply. It uses a different method for selecting Shogi promotions, and I would like some feedback on whether this is better than the old method ("Promote? yes/no" links above the board), or that it just is confusing. What happens now is that the destination and a square next to it get highlighted in red, and display the two pieces between which you must choose. Clicking one of those then completes the move. So double-clicking the destination is enough to promote.
The AI is now also searches deeper on lines with checks in them, with as a consequence that it even sees the mate-in-2-threat in Tenjiku Shogi after 1.j6 SEn11 2.BGi6 at a setting of 2 ply.
[Edit] An alternative method for the promotions is to define special highlight markers for promotion and deferral, rather than highlighting by (red) color and displaying the pieces to choose between. That could be less confusing than just seeing pieces appear that don't belong there. The problem is that square-covering markers would have to be dependent on the square size that is in use. But using a red disk with a + on it for promotion, and a green one with an = for deferral, which just fit into a 33x33 cell might be usable.

The I.D. (at 2.5 ply) beat Jocly (at 10 min) at the Modern Tenjiku Shogi correspondence championship!
