Bidding over a lead directing double

[jdaming]

I am referring to any situation that the opponents have made a lead directing double. I understand there can be different treatments over different sequences and welcome any and all advice.

 

First, what in your opinion is "expert standard" for bids like redouble, pass, and a new suit.

 

Second, what is your favorite method or if you know what do other top pairs use?

 

Thanks in advance

I like redouble as usually to play, if that is a plausible interpretation. If not, it shows first round control. In a situation where your main problem is whether to bid 3NT and from which side, redouble should probably mean something else but I don't have any special agreements about that.

It's difficult to lump ALL auctions where they've made a lead directing double in the same category. I'll comment on three such auctions, and leave the rest to the other posters.

 

1. Auctions similar to 1♠ (2♣) 3♣ (Dbl), where we have bid a major prior to a cuebid which was doubled. Expert standard is XX = 1st round control. I'm not sure whether expert standard is weakest action = returning to the trump suit or weakest action = pass, although I suspect it's the former. Regardless, the other one of these shows mild extra values.

 

2. 1NT (p) 2♣ (Dbl): A non-standard interesting treatment here is to play that pass is a serious attempt at penalties (e.g. AQTx) or a hand with no club stopper. Pass is a hand interested in co-operative penalties, a hand with usually four clubs to at least an honor but not a very strong holding. 2♦/♥/♠ retain their normal meanings, and show tolerance for a club lead. After a pass, responder redoubles if he can tolerate opener passing with the "serious penalties" hand, and otherwise bids as if opener had bid 2♦. I am not sure what expert standard is here, but I think it's pass = concerned about a club lead, XX = penalties, bids = normal meaning, unconcerned about a club lead.

 

3. ... - 4x - (Dbl), where 4x was Kickback. An interesting treatment here is to play that pass denies a control in x, and any bid retains its normal meaning. XX confirms a control and asks the Kickback bidder for keycards. I am not sure what expert standard is here.
