Fantastic Simulgear dueling board. I have enjoyed many a game trying to both perfect and counter the surprising plethora of strategies on both American and Japanese sides. I think one of the biggest factors in the game design was the chose number of allowed moves which really makes you choose what you have to do.
One of my favorite boards on the site. Complex, but master-able. challenging, but fun. And very different game-plays just based on how many players or level of fog. Two hints watch out for the dice modifiers and look for the few safe spots on the board (also some of those are much more important)
A little confusing at first, but gets better with each game played.
Though it is a little weird when you think you're doing great and then suddenly the games over and you lost.
