This is the second of three Hanoi5 hands used in Round 1.

Scoring: MP

Board 10. Bidding Script: North/South do not bid

With 14 top tricks in NT, I almost didn't include this hand, but I wondered about the problem of WEST hand if EAST bid a waiting 2 bid. 2=2=3/4NT could lead to some problems as you preempt yourself. West hand is a solid 26 hcp with extras on top of that. Would 4 over 3NT rebid be stayman? Gerber? Baron? Would East consider jumping to 5 over 3NT (super gerber)? Would anyone raise 3NT to
4NT thinking blackwood? I thought there was enough room for some problems, so here it is. The 7NT = 10 is very generous, but I want to have a 10 or better available on each hand.

7Ne/w=10, 7Cew=5, 6Ne/w=2


7N W 11
7N E 3
7C W 3
7C E 1
6N W 6
6N E 1
6C W 1
4H W 1


7N W olegru - driver733
7N W tylere / bid_em_up
7N W mbodell - javabean
7N W karlson/threenobob
7N W elianna/awm
7N W lobowolf/bkjswan

Some of the auctions, even that ended in 7NT, could be revisited.

Especially if your 2 promises 6, although even promising 5 it is easy enough when partner shows 1 key card, and on the Q ask shows the Q and the diamond K.

It would have been a more challenging hand to bid for some if we didn't have the spade Q, but I knew we had 14 top tricks.

But it was a good chance for my partner and I to talk about which of 2 - 4 and 2 - 2 - 3 - 4 is key card (answer, both, but on this hand the first one should be used).

I honestly thought this would be the flattest board of the set.

It would have been more challenging if East had held xx Ax Kxx Qxxxxx. For me that would move it from obvious opening bid to obvious pass. For most pairs it would also make it a clear 2 response to 2.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

We had probably the simplest auction on this board...

2 - 2 (A/K +)
4N - 7N

We (almost) had the simpler auction

1 - 7NT

on our table until I tried to be scientific and ask partner if he has a possible source of tricks in the auction, completely forgetting that I should just blast to 7 anyway.

1 - 2(1)
2(2) - 2N(3)
3NT - 5NT(4)
6NT

(1) Clubs GF or balanced GF
(2) Any minimum (<14 ish)
(3) Balanced GF, asking for 4 card majors
(4) Quant to 7NT

I think your scores are pretty good. If you matchpoint the results achieved by the 27 participants and then scale the scores to a 12 top, you get:

7N = 9
7C = 4.8
6N = 2.3

I opened a 10-12 NT sitting E. Partner sandbagged to make sure I didn't have everything BUT the A and then blasted.
I once yelled at my partner for discarding the 'wrong' card when he was subjected to a squeeze that I allowed by giving the wrong count with too high a card. Now he's allowed to pitch aces when the opponents have the king in the dummy. At trick 2. When he could have followed suit. And blame me.

I passed and then bid 2D. We bid:

2C 2D
2H 2S
2N 3N
4C 4D
4H 4N
5H 6D
7N

2H kokish
2S forced
2N balanced GF
3N clubs
4D keycard
4H 1-4
4N king ask
5H HK
6D DK

At the point 7N was bid I assumed han would bid 6S if he needed a 6th club to count 13 tricks so it seemed like a good auction. As it was xx Axx Kxx Qxxxx was enough for 7 with his hand so he didn't need to bid this.

I don't know if Han could have bid 4D keycard himself over 3N but had he then I would have shown 1, he would have asked for the Q, and I would have showed it plus the DK and that would be good enough also.

We had some superfluous bids.

1 1[1Di]
2 ...

There was some potential ambiguity now as we play kickback therefore ...

... 4 agreeing clubs
4* 4 *cue not denying diamonds as 4 would be kickback
4NT* 5** *diamond cue **Kickback
5 7NT

Not playing kicbacks and other fancy stuff we bid:

2 - 2
3 - 4
4 - 4NT
5 - 5
5 - 5
6 - 7NT

2 = precision (6+ clubs)
2 = relay
3 = bad hand
4 = SI+, sets clubs
4 = forced cuebid
4NT = rkcb
5 = 1 out of 5
5 = queen ?
5 = yes, and nothing special on the side
5 = kings ?
6 = one
7NT = too many tricks

One auction went...

2C - 2D
4N - 7N

Where 4N was 25-26 hcp. This pair knew they had between 36 and 37 hcp. In theory they could be off an ace (likelly down one), or off the club king (from the 7NT bidders point of view) making it a 50% grand slam.

Another auction went
2C - 2D
3N - 4C
4N - 6N
Pass

Where the range of 3NT probably should not be ambigious, but the 4C bidder wasn't sure what 4C meant, but he was sure it was not Gerber.

I think I was right about the possible risk of bidding this hand with a waiting 2 response. Here a sucessful and unsuccesful auction are both gambles it seems, although the successful one was at least an educated guess.
