Your bid after partner doubles a pre-empt and it is raised

[wackojack]

This came up in a team league  match yesterday. I was criticised for underbidding

Your hand at Game all:
  10
  K9632
  K105432
  Q

LHO opens 3
Partner doubles
RHO bids 4

I passed which I now think was wrong.
I think partner is likely to have 2 aces.  Then what a is min take-out double with 2 aces?  Something like this:
  xx
  AJxx
  Axx
  KJxx
Partner needs to have about this strength of hand to make a take-out double of 3 .  And we see that 5 is a very reasonable contract.

In fact partner had
  8
  AJ1075
  A6
  AK1096
So 6  is an excellent contract.

The actual bidding went:  3 - (x) - 4 - (p); p-(x) -p- 5 ; all pass

Non leaping Michaels would have worked well on this hand.  The bidding I think would have gone 3 - (4 ) -4 - (5 ); p - (6 ) all pass 

The opps only got to 5 at the other table but I was criticised for underbidding.

Agree Non-Leaping Mike gets you to slam. I do not see getting there without it.

On your auction without it, I'm not sure about 5 over 4 . Maybe 4NT (two suits)?

After (3S)-X-(4S) I would like a bid of 5m to show length in m and enough values to make 5m a reasonable contract.  Not hard to think of hands where that agreement would be useful.  So it makes sense for 4NT to be any two-suited hand.
With a decent 6-5 and two stiffs, opposite a TO double of 3S,  then 4NT, two-suited, will certainly get us to a reasonable contract. Will it get us to 6H? Perhaps. I bid 4NT. pard bids 5C, I bid 5D, then we will play this in however many hearts pard bids.  Probably that will be 6. I suppose pard has to worry that if I am 1=5=6=1 I might well bid 4NT holding D: QTxxxx instead of KTxxxx. But he has a good hand and so he goes for it. Probably.

While I see non-leaping Michaels as being the best route to find the slam, you have to live with the choices your partner makes ahead of you.

Given that partner made a takeout double and you have two potential places to play.  I think 5 , albeit almost certainly safe, does not give the full playing-strength of the hand, while retaining a modicum of safety if partner overbid.  A direct bid of 4NT is called for to show two suits; pulling clubs to hearts, and probably raising either red suit to slam.  I feel like the pull of 5 to hearts shows a mild red suit try, while if partner does not show clubs over 4NT, then we have the double red-suit fit, and I am willing to try the slam now.

A delayed 4NT (waiting for the reopening double) just seems weird.  If it were natural, why not pass the second double?  I think the best interpretation is a balanced no clear-choice sort of hand, throwing the decision back to partner.

This  showed up at the latest W-Workout , and am I mistaken that "we"  duplicated  Jack's auction?
I thought 2nd had was worth an old-fashioned Michaels,  but was having a brain cloud and spoke about overcalling 4NT  (yes-two places to play)  not realizing that 4!S was available.   Perhaps it is also a brain cloud to think that pushing directly to the 5-level  is warranted.  but after all  in the event he did do that.

I can certainly see the merit in bidding 4NT to show a 2 suiter.

Jim's idea was interesting.  As I understand it:
3 - (x) -4 -(4NT)
p - (5 ) - p - (?)

A bid of 5 shows a minimum free bid of 4NT that could show a 2 suiter.   
A bid of 5 shows a slam interest  2 suiter (5 does not necessarily mean 6 +5 ).

In that context what is my hand worth?  OK too strong to pass over 4 and therefore I bid 4NT to show the 2 suiter.  And not strong enough to bid 5 over partner's next bid of 5 so bid 5 ?  It would then be up to partner to assess whether or not to try 6 or sign off in 5 .

Sorry Blu I cannot reliably recall now the details of the auction at the W-Workout.
