Assuming 3 shows something in diamonds (not xx), i’ll try 4. 6is cold if N has something like: AKxx xxxx Qxx Ax And very good even with three small diamonds

Slam is still possible if partner has something like A K and A. I would like to bid 4to show my club control and slam interest but A K concerned that might be natural, so will bid 4and see whether partner can cue a major. If she bids 4.I can bid 5and if she bids 4then I’ll try RKCB.

4. The implication of 3is that he has weak hearts. 3NT may only make if diamonds run, while if they do run 5will usually be OK also and it will often be safer when diamonds do no run. Harmless to try 4on the way to 5in case he has 4-4-3-2 with A K and A, for example, when slam will be good.

I would bid 4. I think p should have some sort of interest in diamonds, since he didnt bid 3N over 3. 5should be pretty safe and we make 6 on many hands.

3NT. Partner is likely 4423, and even if they have good strength e.g. AKxx Jxxx xx Axx we still need trumps to break. I think I have shown interest in playing in diamonds, so if partner has 4432 they may bid 4and we can cue-bid on the way to 5or 6.

4 – A cue on the way to 5, to give pd a chance to raise with max.
Bar Tarnovski (ISR) WIM: 3NT
I need a bit information about their system . they might have agreement of bidding strength with Diamond fit – that would change my thought).
In case that 3is just showing strength I would bid 3NT . if 3is a fit Diamond + strength then there is reason for bidding 4cue bid looking for slam in diamond or
just play in diamonds.

Slam being cold requires an excellent hand from partner, along the lines of Axxx xxxx Qx AQx. However, this hand-type is not what I would expect from partner. Most notably, A is not partner’s most likely spade holding, and 3 clubs are not suggested.
The other scenario in which slam may make is partner holding both black aces, with some useful heart holding, and opponents erring on lead. Once again, the assumption that partner holds A seems ill-advised to me.
Finally, with 3 aces and 3 diamonds, partner would commit a grievous error by letting us play 3N. A grand may conceivably be reached all the same.
Finally, I believe 3N is far superior to 5, and 4N is quite dangerous.
Conclusion: 3NT.
Adam Stokka (SWE) 3NT
3NT. I dont know really, i dont like the system.. but i bid 3nt then. Not happy.

If 4is control asking (in Diamonds) i go for it since you can play either 6, or 4NT. If not I believe 4is better as a cue and if pd is interested and cooperates with a cue you can use RKCB, if he is not he can signoff in 4NT. Answers: 4 = 5 experts 4 = 4 experts 3NT = 5 expert
