5-Level Agreements?

Here's a situation that is not all that uncommmon, but caused a bit of a stir at our online table recently. Each of the four players involved had different opinions of what 5-level bids should mean in this sequence:
1S-1NT*-3C-4S**-?
*-forcing
**-the 3 card limit raise

What agreements to you play here? How would you handle this hand (the one actually held at the table)?

From Champaign--Updated

I'm back from a quick trek to Champaign for the regional there--we had a fun squad but unfortunately never quite got things rolling. Here was one interesting declarer play problem:

The bidding is a bit different because of the system you are playing--the north hand deals and east-west pass throughout after the initial overcall.
1C*-(1S)-1NT**-2C***-2D****-3NT
*15-20 pts any shape
**9-11 balanced
***Stayman
****No major
West leads a standard deuce of spades and East plays the Jack. You duck and when East continues with the Queen, your King holds, West following. What now?

Nine tricks could be there with a diamond finesse and a 3-3 club split or a miracle in diamonds, but from the carding it looks like the spades are 5-3. The opps can't cash more than 4 immediate tricks if that is the case, so the best line is to give up the 3rd spade now, cutting the defense's communication. You will make when West has King-third of diamonds because he'll be squeezed if East cashes out the suit (if not, clubs were 3-3 all along) and you can set up dummy's 4th diamond otherwise. The other two hands were:

AKQ--A Bad Holding?

How bad can a holding of AKQ in a suit be? My dad and I do at least one Bridge World Challenge the Champs set each time I'm home...since it was Mother's Day this weekend, we got another opportunity to shine this afternoon. We play Precision with a 14-16 Notrump. Two problems:

1) Jxxxx xxx Ax AKQ
Partner opens 1D (11-16, could be short if 11-13 balanced). You respond 1 Spade and partner bids 4 Clubs (a club void and spade support). What do you bid?

2) Ax Ax KT9xxx Axx
What is your opening bid? You can choose from 1 Club (strong), 1 Diamond (explained above), and 1 Notrump (14-16).

2 From Lake Geneva--Updated

Two weekends ago my college friend and bridge partner Jason Rosenfeld came into town from Boston for a weekend of bridge playing. We went out to the regional in Lake Geneva for Saturday and Sunday--here are a couple of problems.

RHO opens a weak 2 Hearts in first postion. What's your approach with this hand?


Sorry for the late follow-up. I think I made a mistake when I posted the defensive problem--I have to confirm with Howard--hopefully I will have more on that later. I am interested to discuss the bidding problem though. I felt uncomfortable overcalling on the first round thinking it was too much of a distortion. I also felt very uncomfortable keeping silent. I decided to apply Jonathan's approach, hoping my partner would read me for this kind of hand. So I passed and LHO bid 2NT. Jason passed and RHO bid 3 Diamonds, alerted and desribed as a "medium hand." Undeterred, I entered with 3 Spades. My LHO thought briefly and doubled, which ended the auction. Jason's hand was a fantastic Qx AKTxx x KJTxx and I was pretty much cold. Plus 730 went well with our teammates' +200 against 4Sx at the other table (my opposite number overcalled 2 Spades). In retrospect I like the way I handled this one--of course the result didn't have to be this great, but I think it gave us a decent shot at figuring out what was going on in this tough auction.

And a defensive problem from my friend Howard Liu in one of the other Saturday knockout matches:

The auction, with your side passing throughout, is: 1H on your left-3H preemptive-4H

Partner leads a 3rd-5th deuce of diamonds to your ten and declarer's queen. Declarer plays a heart to the king...your move.

Almost...

This was a near-gem from last night's club game in Elmhurst--I was playing with Kenny Zuckerberg. I was third in hand--Kenny dealt and passed and RHO opened a 12-14 notrump which became the final contract. I led a low spade...this is what I saw:

My lead ran to Kenny's jack and declarer's queen. Declarer led the jack of clubs, covered and won in dummy. Declarer continued with the queen of clubs and the ten, Kenny following. Declarer pitched a heart and i did the same. Kenny won the next club, declarer shedding a spade and me a diamond. Dummy won the spade continuation and declarer cashed her last club (her 6th trick), pitching another diamond from her hand as I blanked the king of hearts. She duly took the finesse into my king and I cashed out but in the 3 card ending declarer, pitching behind Kenny who came down to AT of diamonds, threw the ace of hearts from her hand and made the last trick with the king of diamonds. What if I hadn't blanked the king of hearts, throwing a diamond instead? Now, assuming declarer took the heart finesse, when I cashed out, we would have caught her in a legitimate squeeze--here is the 3 card ending--

My hand is South in the diagram with dummy's cards immaterial. On the last spade, Kenny would have pitched his heart and declarer would have been bamboozled.

I took a couple of liberties with the spot cards to make the squeeze work (we were actually short a couple of tens to pull it off in real life)...but here is the hypothetical full deal:

Too Tough...

I just got back from a quick weekend at nationals. I had high hopes for a good showing in the swiss teams, but they were dashed by a non-qualifying first day effort. These two hands from our second round match were kind of typical of the day--

My partner and I had a nice auction to 6 Clubs--uncontested it was 1H-2C-3D*-3H-3S-4D-4H-5NT**-6C *=splinter **=choice of slams
After the spade lead my partner cashed the king queen of clubs finding jack-fourth offside and eventually conceded down two. At the other table our opponents bid only game in hearts.

Then this two hands later:

I shifted the directions on this one so we were sitting East-West. My partner opened 1 Diamond, South overcalled 2 Clubs, I bid 2 Diamonds. North and East passed and South doubled. North responded 3 Diamonds, South bid 4 Clubs and North bid (gag) 6 Clubs. I'll add that North is a top-ranking expert player...his luck was certainly in this time as both the king and jack of hearts were with the opening bidder...gin. So we got blitzed in that match and never made it back to average. There's always Washington, DC.

2 Problems from GNT Weekend

Here are a couple of problems that came up for me yesterday in GNT qualifying--

RHO passed as dealer, I passed and LHO opened 1 Diamond. Partner overcalled 2 Clubs, RHO made a negative double and I tried 2 Hearts. Now LHO bid 2 Spades and partner bid 2 Notrump passed to me. My bid is?

I opened the south hand 1 Notrump and partner raised to game. LHO led the 2 of hearts to RHO's queen. Eight tricks are in view but you need nine--how do you plan the play?
