Responses
Following the Lionel double, the partner of the double responds as follows:
(1NT) - dbl - (pass) - ??
:pass = 10+ hcp, all subsequent doubles for penalty
:2 =
pass-or-correct bid In the card game bridge a pass-or-correct bid (or convertible bid), is a non-forcing bid that asks partner to pass or bid differently based on her/his holding. Pass-or-correct bids are generally used as responses to multiway bids.
A typical example ...
(doubler to pass or bid second suit)
:2 = Non-
forcing, diamond length (typically 5+) with heart tolerance. Doubler can bid 2 with hearts as second suit and less than two diamonds.
:2 = Natural, non-
forcing
:2 = Weak Raise
:2NT = Invitational spade raise without a singleton side suit
:3// = Invitational spade raise with singleton or void in bid suit
:3 = preemptive raise

(1NT) - 2 - (pass) - ??
:Pass = to play
:2 = to play
:2 = weak raise

:2NT = invitational heart raise
:3 = preemptive

, using Lionel has the consequence of losing the penalty double over opponent's 1NT. Although this is often seen as a loss, Lionel Wright argued that this loss turns into an advantage as it opens the possibility to defend 1NT doubled with split points between you and your partner. As a balanced holding of the majority of points is far more likely to occur than holding the majority of points in an imbalanced way, a conventional non-penalty double over 1NT holds the potential of paying-off on many hands. Also, non-penalty doubles are more difficult to deal with than traditional business doubles.
