Negative Doubling to show BOTH Majors

This post builds on the knowledge learned in previous posts. Please read them first:
Introducing the Negative Double - Auctions showing Spades
Responding to a 1 Level Negative Double when RHO passes
Responding to a Negative Double when RHO raises 1 level
Negative Doubles to show Hearts
Responding to a Negative Double with Hearts RHO Passes
Responding to a Negative Double which shows Hearts when RHO raises 1 level

Doubling at the 1 level to show both majors is a slightly different auction than doubling to show either ♠ or ♥.

This is the VERY SPECIFIC auction we are looking at:
Partner Your Right Hand Opponent You!
1♣ 1♦ Double

For this Double you MUST have BOTH suits. After all, both are majors and both are very important. You only need six (or more) HCP (High Card Points) because Partner is only required to bid at the 1 level.

BIDDING the suit (rather than Doubling) at the 1 level NO LONGER shows a FIFTH card in the suit and still shows only six (or more) HCP. The reason bidding only shows a four card suit is that in order to Double you would NEED to have four cards in BOTH majors. If you have only one four card major you would still need to tell Partner about that four card major so therefore bidding the suit needs to be only a four card suit, but you could have more of course.

So this auction:
Partner Your Right Hand Opponent You!
1♣ 1♦ 1♥

Bidding 1♥ only shows a FOUR card suit (you could have more) and six or more HCP (you could have more) and is still a forcing bid.

and of course this auction:
Partner Your Right Hand Opponent You!
1♣ 1♦ 1♠

Bidding 1♠ only shows a FOUR card suit (you could have more) and six or more HCP (you could have more) and is still a forcing bid.

Does the "Double" show any particular length in each suit?

Good question! It does!

With two FOUR card majors ALWAYS make a Negative Double.

♦T4
♣864
♠KQ92
♥AJ82
♦T4
♣J64
♠KQ92
♥AJ82
♦T4
♣A64

On Hand A, Hand B and Hand C you would start with a "Double" to tell Partner you have both majors.

With two FIVE card majors ALWAYS bid the higher ranking suit first -- 1♠ in this case.

Partner Your Right Hand Opponent You!
1♣ 1♦ ???

♣64
♠KQ942
♥AJ842

♣J4
♠KQ942
♥AJ842
♦4
♣A6

On Hand D, Hand E and Hand F you would start with a 1♠ bid. This just tells Partner you have FOUR of them. You will show this distributional hand with your next bid.

With both a FOUR card major and a FIVE card major make a Negative Double with a weak hand -- less than 10 HCP.

♠KQ932
♥J842

♠K942
♥AJ842
♦T4
♣64

On Hand G, Hand H and Hand I you would start with a "Double" to tell Partner you have both majors.

With both a FOUR card major and a FIVE card major bid your FIVE card major with a strong hand -- a good 10 HCP or more.

Partner Your Right Hand Opponent You!
1♣ 1♦ ???

Hand J Hand K Hand L
♠AK985

♦T4
♣64
♠KQ932
♥AJ84
♦T4
♣64
♠KQ42
♥AJ842
♦T4
♣A4

On Hand J and Hand K you would start with a 1♠ bid to tell Partner you have at least four ♠. You can always bid ♥ later on.

On Hand L you would start with a 1♥ bid to tell Partner you have at least four ♥. You can always bid ♠ later on.

That's quite a bit of information. Let's practice! That might make things a bit more clear.

On the following hands Partner opened the bidding 1♣. Your RHO (Right Hand Opponent) overcalled 1♦. It is your bid. What will you do?

Keep in mind that you do need values to bid.

Double if you have at exactly four ♥ and four ♠.

Double if you have at EITHER five ♥ and four ♠ with a weak hand OR five ♠ and four ♥ with a weak hand.

Bid a four+ card major.

Bid 1NT to show stoppers in the Opponent's suit with 6 to 10 HCP.

Bid 2NT to show stoppers in the Opponent's suit with 11 or 12 HCP.

Bid 3NT to show stoppers in the Opponent's suit with 13 to 15 HCP.

and last (but not least!) just "Pass" if you have nothing to say.

Here goes. Remember the auction was:
Partner Your Right Hand Opponent You!
1♣ 1♦ ???

How many High Card Points (HCP) do you have? What will you bid and what does that tell Partner?
