Rebidding after Partner makes a Negative Double showing both Majors and RHO Raises 1 Level

This post builds on the knowledge learned in previous posts. Please read them first:

and most importantly:
Negative Doubling to show BOTH Majors
Rebidding after Partner makes a Negative Double showing both Majors

After your Partner makes a Negative Double, sometimes your RHO (Right Hand Opponent) raises their partner's overcall and you are no longer forced to bid. In an auction where Partner has shown four of both majors and you have four of at least one major you still want to tell Partner. But now the level you respond at will change since your RHO took up a level.

Let's look at this auction:
YOU! Your Left Hand Opponent Partner Your Right Hand Opponent
1♣ 1♦ Double 2♦
???

and here is your hand:
♠KQ92
♥J2
♦T84
♣AK84

You want to compete. You have a ♠ fit. If the Opponents did not interfere and Partner had responded 1♠ you would have raised to 2♠. You can still do that. That still shows a minimum opening bid.

What if your hand was stronger? What do you do then?

With a VERY stong hand, say this one:
♠AKJ9
♥82
♦AT4
♣AK84

just like before you can just go right to game. Bid 4♠. Partner is supposed to have at least 6 HCP to make the Negative Double. You have 19 HCP! That should be enough to make a game.

With a more medium type hand you can jump one level. Now you need to bid at the 3 level since the Opponents competed with 2♦.

So with this hand:
♠AKJ9
♥82
♦96
♣AKJ84

you would jump to 3♠. That tells Partner that you have more than just a minimum opener, but not quite enough to bid a game.

Remember you can add Dummy points to your hand even though you will be Declarer.

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

On the following hands YOU opened the bidding 1♣. Your LHO (Left Hand Opponent) overcalled 1♦. Partner doubled. You have agreed to play Negative Doubles and this is one! Partner has at least 6 HCP and at least four cards in both majors. Your RHO (Right Hand Opponent) bids 2♦. It is your bid. What will you bid and what does that bid show?

So the auction was:
YOU! Your Left Hand Opponent Partner Your Right Hand Opponent
1♣ 1♦ Double 2♦
???

With a minimum opening hand (and a fit!) bid just 2 of the major. This should show up to a bad 16 points.
With a medium opening hand (and a fit!) jump to 3 of the major. This should show a really good 16 points to 18 points.
With a maximum opening hand (and a fit!) bid 4 of the major. This should show at least 19 points.

(Remember to count Dummy points!)
