These are also (confusingly) known as Control-Showing Doubles, which they absolutely are not
! These are the opposite side of the coin to Non-Penalty Slam Doubles. These are used when it is our
hand and opponents have sacrificed over a high-level contract that we have bid, in a sequence where 2nd-in-Hand over their sacrifice is not
the Captain of the Hand (or where there is no firm Captain). The question at hand is whether we double their sacrifice or bid one more and Control of their suit has not yet been specifically been shown by cue-bids or an Asking Bid response. Now:
- Passes with 1st Round Control of their suit (at the 6-level) or with 1st or 2nd Round Control (at the 5-level)
- Doubles with no such holding.
, or bids
depending on their own holding.
Bear in mind that the above does not
apply when the Captain of the hand is sitting immediately over the opponent making the sacrifice bid, and does not
apply if the question of control of their suit has already been settled. Most importantly, these do not
apply when we are in the middle of an Asking Bid sequence: If the sacrifice is of a pre-emptive nature, then Pass by the Captain of the Hand is Lebensohl
, demanding a Double from Partner, and therefore cannot be a Control-Denying Double. Similarly, if the sacrifice is not
pre-emptive in nature (ie: not jumping at least one round of bidding) then Double and Pass are "asking" backwards.
