You are South and dealer. Imps. All white. East overcalls 1S or 2S if available. West will raise 1S to 2S or double if South cue bids spades.

Two-way pass:

pass 1♦ (1♠)
2♥ (2♠) 3♦
4♦ 5♣
6♦

pass = 0-8 or 15+
1♦ = catch-all, 9-14 no 5 card major
2♥ = nat 15+
3♦, 4♦ = nat 5+ cards, nat slambound
5♣ = no major suit cue, club ace
6♦ = very hard to know if 7 is there...

Silent Club:

1♣-2N strong; GF with both minors, no shortness, longer diamonds
3♣-3♦ ask; 2254
3♥-3♠ QP ask; min (6 or fewer)
3N-P

Our system showed this shape via a zoom high enough we didnt have any interference issues.

You know ♦KQxxx and ♣Axxx is enough for 6♦ to be good, why no further investigation ? at IMPs 5♦ is not to be feared.

Not sure what I'd do with an IMPrecision start. I'll be interested to see Adam's post.

1C-1S(2S) 16+, 5-8 bal or 5-10 diamonds
P-3C nf min or trapping, GF 5D/4C
3D-3S fit, punt
4H-5D RKC, 2 and Q, nothing else
6D

If responder had less than GF, I think his options would be double as takeout or 2N as good/bad (confirming diamonds). After 3C GF, opener can probably infer that pd is not 1354 (else double) so showing a diamond fit seems more useful than hearts (not at all sure on this point). After the 3S punt bid, I'd infer that partner doesn't have wasted values in spades and a game in diamonds seems safer than 3N. Plus we have the possibility for a nice surprise (which we get) after RKC.

Am I missing something? It looks like a spade lead holds this contract to 5♦, and that's with the favorable J♥ showing up in North's hand (same thing happens without the J♥ on a more normal 4-2 heart break). With no fitting shortness and only 18 QPs, that's generally too pushy for me.

[straube]

The hand in fact made only 5D. Without knowing about the HJ I should probably bid only 5D as well. I know I can pitch whatever spade cards partner might have on the AKQ of hearts, but I need all 5 heart tricks to pitch two clubs, too.

[akhare]

1♣ - 3♣ (16+; 2=2=5=4 exactly)
3♦ - 3♠ (QP ask; 6 QPs)
3N

TOSR zooms past the interference, but with a combined total of 18 QPs and uninspiring combined shape, but difficult to ignore the safety of 3N unless looking for a swing. Others may be more gung ho on the prospects of this hand and it may come down to hand evaluation.

Responder's holding may very well be xxxxx of ♦ with say AK of ♣ and Q♠.

[Free]

Another difficult one imo:
1♣-2♦-(2♠) (16+ ; GF 5+♦ unbal)
3♥-3♠ (5+♥ ; dunno what else to do)
4♦?-4♥? (hand is too good to bid 3NT imo ; not sure here, might be Kickback Turbo, might be scrambling)
...?
No idea, I guess we'd probably end up in 4♥...

[Siegmund]

I tried it with a few different Polish variants (starting 1H) and all roads appeared to lead to 3NT.

2NT (Relay) - 3♠ (5♦ & 4♣ & 2-2 Majors) -
4♦ (Beta) - 4♠ (3 Controls) -
5NT (Any extras?) - pass (No) - all pass

This is a problem hand for C3 - Alternate Auction:

1♣ - 2♣ -
2♥ (SAB-3) - 2NT (exactly 2♥s) -
3♦ (SAB-3) - 3NT (3 Controls) -
all pass

Please include the spade interference.

[Lord Molyb]

Without interference:
P - 1♣
1♥ - 1NT
2♥ - 3♦
3♠ - 3NT
P

P = Forcing
1♣ = Ask
1♥ = 15-18 points
1NT = GF
2♥, 3♦ = natural
3♠ = probe
3NT = clubs stopped

With interference:

P - 1♣ (1♠)
2♥ (2♠) 3♦
3♠ - 3NT

2♥ = 15-18, 5 hearts
3♦ = GF, natural
Rest is the same

[awm]

1♣ - 1♠ (diams or bal) - (2♠)
Pass - 3♣ (5+♦/4♣ forcing)
3♦ - 3♠
3nt - Pass

It's hard for opener to make a real move towards slam here given the range of our 1♠ response; responder has a total maximum. Perhaps responder can/should do something, but with a flat 11 opposite what's probably 17-19 balanced it's not clear to push on there either.

Done, see original edited post above.

[antonylee]

I would open a SNT playing Polish and likely reach a quiet 3N, but assuming an upgrade...
1C[Polish] 1D[weak, or intermediate with minor(s), or rare GFs] (1S); 2H[strong] (2S) X[(54)+ minors]; 2N 3D; 4D[optional RKC]-5D[2+Q] and I'll probably bid 6 hoping for a favourable heart position.

[yunling]

1♥(standard)-2♣(either 6-9 6+♦ or some invite)
2NT(bal or 4♠, 16+)-3NT

Don't think east will interfere here.
