The original Unashogi is quite interesting, but has a fatal flaw. Because King drops are unrestricted, impasses are easily attained by dropping the King into the promotion zone, making draws very common, as most pieces have a forward bias to them making a King on the far side of the board very difficult to mate, especially if surrounded by friendly pieces.

I am working on a variant that will fix these problems, called Unashogi II. It solves the impasse rule by restricting King drops to the first three ranks. However, this also requires a second rule restricting entering the promotion zone while the King is in hand to prevent players from simply stalemating an in-hand King. I am currently testing two different versions of the rule, one only allowing entry when the friendly King is placed, and the other only allowing entry if the enemy King is placed.
