IMPs

1:

There was a certain amount of excitement on this board, but what do you do now and what does it show ?

2:

2♦ ? 3♦ ?

3: A hand we got horribly wrong and were lucky to only lose 2 imps. It raised the following questions.

(2♦ natural weak)-2♥-(P)-2♠ is this forcing ? Is 3♠ instead of 2 big natural and forcing, splinter or fit (we play a fair few fit jumps in our system)

4:

Pass or double ? 2♠ is classical natural weak 5-9 6cs (sorry vul wrong, is love all)

• I think 4♥ is fine, though 4♦ seems reasonable as well. I do not have great methods to show this hand: I like my splinters to be three-suited, but we're very strong for a preemptive raise.
  
• 2♦, and in my opinion it is not close. I have a rule to never upgrade if I open a long minor hand and partner responds my short major. Taking away space here is so bad, it's difficult to overstate how many problems this creates for partner. I pair this with 1♦-2♥ weak (4-8) natural NF, eliminating some potential problem hand types opposite these unbalanced hands. Keep in mind that if partner passes 2♦ they have 5-9, what are we missing opposite that (and what are the opponents doing)?
  
• Yes, I play that changes of suit by unbid hands are forcing. 3♠ is a fitbid for me. Some people play that 2/2 or 2/1 by advancer is not forcing, they might have more issues here.
  
• Pass seems clear to me. No borrowed kings theory here.

1. 4♦ with 3 controls and a void. 4♥ would be pre-emptive
2. 2♦ unless you have a way to show an intermediate jump. Even if you did, not much point with ops. passing. Playing my unbalanced♦ I'd bid 1♠ unlimited given 1♥ is either Major.
3. 2♥ for me would be some strength and an asking bid, so X if applicable. 2♠ non-forcing ♦ weakness. 3♠ self-sustaining invite expecting a raise opposite a max.
4. Nothing to get excited about so Pass.
