Decisions over their 4M preempt at IMPs

Recommended Posts

Some problems (scoring always IMPs):

 

1. None vul. Q 103 AJ107532 A32.

 

P P 4H ?

 

Do you bid 5D? If not, what's the "smallest alteration" you could make to this hand to get yourself to bid 5D (examples of small alterations are Qx x AJ10xxxx Axx, Q 10x AQJxxxx Axx, Q 10x AKJ10xxx Axx, etc.)? If yes, what's the smallest alteration that would get you not to bid (e.g. Q 10x A109xxxx Axx, etc)?

 

2. None vul. 8 KQ5 QJ107 Q10852.

 

P P 1D 4S

?

 

Do you Pass, Double, bid 4NT, bid 5D? Again, small alterations that would change your mind to each of the bids you didn't make here are welcome.

 

3. None vul. A9 J87 AK8653 J7.

 

P P 1D 4S

X P ?

 

Do you pass or bid 5D? Again, smallest alterations to get you to make the other choice would be welcome.

 

(Yes, I know this last hand is the partner for hand #2, but we can all ignore that and answer theoretically.)

1) yes I bid 5D. If one of my diamonds was in a different suit, i wouldn't. If my ace of diamonds were a small one, i wouldn't. As you can tell from my "alterations" I consider this a pretty clearcut bid, and would bid with a much weaker hand.

 

2) 5D. With 1 less of any suit and 1 more spade I would X.

 

3) 5D (I see a trend). This is pretty close since I'm 6322, but I think either they might make or we might make. If my diamonds were weaker with more strength outside, I would pass with this shape.

Interesting, I thought the first one was the clearest of the lot! Not sure what I'd do on the third one at the table, but thinking about it it has got to be right to bid at IMPs - there's just too much chance that one of the games is making.

1. Pass

 

2. 5D

 

3. Pass, pard's double tends to deny fit in diamonds, and excluding 5D there is no clear spot where to go. Expect to give one ruff or 2 to pard

Well, the consensus seems to be to bid 5 on these hands.

 

I did this on the first one and went for 1100 (yes, I took less than half of the tricks). Wasn't sure whether there was a moral there or just horrible luck. The full hand:

 

[hv=d=n&v=n&n=s654h87dk984ck1096&w=sqh103daj107532ca32&e=sj10982h954d6cj874&s=sak73hakqj62dqcq5]399|300|Scoring: IMP

P P 4H 5D

P P X P

P P[/hv]

 

This is perhaps more of a win for the 4H opening in 3rd seat than a loss for my bid, but there are perhaps fewer ways to win once partner is a passed hand. Of course, my luck was quite rotten. (I'll note that I was even given a trick: small club to the Q on opening lead ended up giving me a club trick, whereas they made 3 trump tricks with a heart uppercut.)

 

[Edit: I tried to prevent the uppercut by playing the 4H bidder for KQ tight and leading A, low . This gave them the uppercut in the present case, unfortunately. I'm not certain what play was best, but decided that LHO might've doubled with K984 and that this outweighed the restricted choice odds.]

 

On the second hand, I do see that 5 is probably best. I doubled, and they made while 5 was just off 1. Perhaps I was traumatized by the first hand into not bidding 5 ever again :P .

 

My partner passed the third hand, and I think this is very close and perhaps it depends on what collection of hands you double on (well, certainly it depends on this, but maybe this collection doesn't vary enough amongst experts to ever change the bid). This was, as I noted above, the partner of hand two.

Full hand is here but I knew my answer before I saw it.

 

1. PASS I have 7 loosers. That means cca 5 down. Partner can't have values to cover all these loosers. If it was after 1st seat opening I would pass too - with values for making 5 partner must double.

A 103 AKJ10753 AK2 is minimum for 5

A103 - AJ107532 AQ2 is minimum for double (3 1/2 tricks)

 

2. PASS Partner can have (semi)balanced hand, where both 5 and 4 can't be made. 5 can cause doubleswing for opps - 4x-3 and 5x-2 or similar.

Double is not good too. I have long diamonds and values in them. Partner must pass this double with most of the hands - and 4x will be often made.

8 435 QJ107 KQJ108. is minimum for 5 (I play acol or wj, 1 shows probably 5 diamonds, 4 is minimum)

8x KQ5 107x A10852. is minimum for double.

More interesting problem is, what you do after partner reopens with double.

 

 

3. PASS I have minimum, 3 top honours and 2-3 tricks. Partner doubled, where is the problem?

x KQ7 KQJ86543 7 is minimum for 5 (very offensive hand)

 

Ok, I wouldn't find good 5 sacrifise. But can I know it during the bidding? No. If 4 can't be made it can be very very bad defence...

1. Pass. I don't know if they make 4, but I sure know I'm going down in 5. To bid here is too much of a shot in the dark to me.

 

2 & 3. Tough one. I guess I'd also double + pass this one. Might turn out wrong, but other bids sound like masterminding to me.

I'm bidding 5 on all of them.

 

The 4 bid got you. But sometimes they'll miss their slam bidding like that, or play the wrong game. I wouldn't worry overmuch.
