mangue: I admit to having a particular fondness for defensive play and for endgames in nearly all variants.  Variants in which those are less frequently seen, or which call for no skill in those areas are less appealing to me.  I consider the thematic Dice Chess Nc3-Nb5-Nxc7-Nxe8 (and mirror image for Black) maneuver to be a blemish in the game itself.  In my experience, it's only executed in about 5% of games, but is threatened in perhaps 25%.  It reminds me of the scholar's mate in chess: fascinating to beginners, but a horrifying thing for a knowledgeable kibitzer to behold.

I'm also not thrilled by compulsory king moves in the single-die version, although one can adjust one's play to account for it, both offensively and defensively.  Two-dice versions typically don't suffer from this defect; dice rolls alone cannot compel a king move, in versions I know of.
