Interesting idea.  I would guess this also means that there is no stalemate.

The rules say that the player must end his turn such that his king has a square to escape to or he loses.  Stalemate is the condition of beginning a turn this way.  I assume this has the same outcome, although the rules don't explicitly say it.

A possible variant, which would free the players from needing to push d, e, or f pawns on the first move, would be to say that the king is comfortable so long as the queen is present (on an adjacent square.)  He's not nervous as long as the powerful queen is there, but when she's gone, he becomes paranoid and requires a space to retreat to.
