This hand ties in very well with your other thread about your tendency to show the same values twice, as I am sure is no coincidence
Over 4
♠, think about what you have already shown: 'I have an opening hand with at least 4 trump, and probably no singleton or void' Delete that last part if not true for your partnership.
Do you have anything extra?
You hold minimum hcp, zero Aces (and hence a very unsuitable hand for slam) and the only redeeming feature is one extra trump... which, incidentally means that your trump Q is not pulling its full weight: if you upgrade for the extra trump, you have to downgrade the trump Q to some degree.
Do you have to bid over 4
♠?
No: partner cannot pass if you pass.
So you can: double to deny interest in slam and to suggest defending
or: bid 5
♥ to deny interest in slam while announcing you do not want to defend
or: pass and let partner, who is still relatively unlimited, further describe his hand
4N, frankly, is not a logical choice. Regardless of the other problems, ask yourself this, any time you are considering keycard: will I know what to do opposite all possible responses?
Clearly, the answer is 'no'.
If partner has all the keycards, you don't know whether to bid 6 or 7... altho maybe you can bid 6
♣ to involve partner
If you are off a keycard, you don't know if 5 is the limit (take away partner's
♣J and replace it with the
♠A) or if 6 is on a hook or laydown.
If you cannot know what to do after a keycard response, don't bid keycard!
As it is, I would bid 5
♥ because my
♣/
♥ length suggests that we will likely make and will not get rich against 4
♠. Note that 5
♥ is the WEAKEST call available (other than double)
