“Voidwood”, or “Exclusion Blackwood”, was introduced by Bobby Goldman. Voidwood is used to show a void and simultaneously ask for key cards outside the void suit.

	[ 1C Pass 1H Pass ] : [ 3H Pass 5D.....the 5D bid makes no sense as a cue-bid (4D would be a cue-bid) or natural bid, hence it is “Voidwood” and says: “I am void in diamonds. Give me your key card answers but ignore the ace of diamonds in your reply”.
	Similarly, [ 1C Pass 1H Pass ] : [ 3H Pass 4S or 5C ] would be “Voidwood” since 3S or 4C would be a cue-bid.
