Ok, then for this you need minimum of two bits - one for kingside Rook and one for the queenside Rook, both would be set if you move the King. You also need to count moves since the last exchange or pawn move for the 50 move rule.
Ah, that one's cool - I've got to admit I've never heard of the 50 move rule.
Also the 3x repetition rule.
And 5x repetition rule
