BOTH PARTNERS HAVE BID IN A NON-GAME-FORCING AUCTION AND THE OPPONENTS HAVE MADE A TAKEOUT DOUBLE

pass after doublePartial support for partner's suit, i.e. three cards.
redoubleSignificant extra strength and not even partial support for partner's suit, i.e. either a singleton or doubleton. However not a void, because partner might gamble to play in the redoubled contract. Shows interest in doubling the opponents for penalties.
