@ Fergus:
I don't know if this has been asked before, but it is not entirely clear to me whether it is illegal to draw by theoretically indefinitely repeating the position during a game, by a series of moves that involve neither checks nor any pursuing attacks on pieces. I cannot yet find a reference to this exact situation on this webpage (nor in a book I own, even). However, the preset I'm playing on right now states that "repetition is to be avoided" (not entirely clear to me that this is an official rule, or one just used by the preset, if it's even enforced by it).
