KiwiTeams 080813 - A few hands

I thought I would celebrate the Central Climbers first win by posting some hands from the match...

Early on Palmer and Wilson found their three-three fit in the simplest of auctions.

The mini-1NT bought a double from west. East with only four points and a balanced hand had nowhere to go so chose to defend. With the distribution being friendly Burrows came to eight tricks. Perhaps he should just play for one club honour to be onside. However trying to combine chances in clubs and diamonds he needed a squeeze to overcome a blockage ...

On the last heart west is squeezed. She cannot pitch a diamond as then the Q will fall making declarer's nine good. A club is equally fatal as eventually north's ♣10 comes good.


Differing opening styles led to a big swing on board 7 ...

Palmer opened 1♠ in the open room and despite having no guaranteed fit Wilson tried for slam based on his sharp honours. Palmer accepted the slam try based on extra distribution - he certainly didn't have extra values.

The final contract was a little thin needing either spades or hearts to play for no losers. When the ♠Q was doubleton and the Q doubleton in front of the jack Palmer had no problem bringing home 12 tricks.

Calvert opened a weak two-suiter. Its a matter for partnership style and agreement but perhaps with some extra distribution and 10 hcp the hand is too strong for 2 even vulnerable.

Even with 18 prime points it is hard for jenter62 to imagine slam especially when she is not even certain of a fit.


An aggressive pass by Palmer helped produce another good swing ...

Down 1 — N-S -200

Would you pass 2Dbl with the west cards. South is hardly maximum for the 2 overcall and on the surface there are eight tricks for declarer - five diamonds, two clubs and a heart. A closer analysis shows that the defense can defeat the contract with two spades, two side aces and two trump tricks (or by forcing declarer off by repeatedly leading spades).

If you consider that Gonthier would have overcalled with the ♣A rather than the ♣K and that Wilson would still double (he could even have the ♣J or K from dummy) with those cards swapped then you see the danger of converting the takeout double for penalties.

Some might argue that Wilson should not double with a diamond void. No one though can argue with the result +200 for east-west.

In the closed room east-west got into a different sort of trouble. After the same start to the auction as the open room Calvert chose to double where Palmer had passed. jenter62 perhaps believing that her partner had four hearts jumped to 3 which effectively pushed her side into a hopeless 3NT.

Personally I am in favour of the useful values sort of negative double rather than the more mainstream "guaranteeing four-cards in the unbid major". Especially when as I suggested earlier I have no intention of passing 2 doubled. In that style most often partner will only bid 2 with a four-card suit expecting a raise. Maybe though even in this style the east hand here is just too strong for 2.

Bridge is a cruel game north-south in the open room and east-west here did little or nothing wrong and lost 9 IMPs for their trouble.

I found this bidding problem to be difficult. There were a number of issues:

The scoring was matchpoints which means that 3NT could easily be a better scoring contract;

We were vulnerable against not so I was wary of bidding 5 and potentially giving up 100s - maybe doubled.

In the end I decided my choice was between bidding 3NT or 5, I also gave some consideration to double hoping to be able to bid my diamonds later. I wasn't brave enough to bid 3NT without a heart stopper so I blasted 5 which ended the auction.

There was good and bad news in the full layout:

Partner had two tricks so that 5 was cold but he also had one quick trick and a heart stopper so that we had 630 available in 3NT. Maybe next time I will be braver.

Another five-level decision gave me a pleasant surprise:

North's 5♣ was close to the last bid I was expecting. I guess north-south had limited methods and north with limited values and lots of distribution elected to blast a suit game. On another day 5♣ might be a fine contract but not today unless you were a defender.

Fullarton Teams Round One Grand Slams

Fullarton Teams Round 1

A couple of grand slams turned up in the first round of qualifying ...

... on both occasions we fell at the last hurdle and only bid the small slam. This is how we could have bid them.

7 ♠ by East

Some might think that 4♠ is a slight overbid with only 15 hcp but with sharp working cards its a reasonable upgrade. With only five spades and these values most would consider the east hand a near maximum for a 3♠ overcall.

When west imagines the slam and asks for key cards the grand slam is a very reasonable proposition after partner shows up with four key cards. West can count six spades, two hearts, two diamonds, one club for eleven tricks. Leaving two ruffs in the west hand to make thirteen tricks or if they are not available there is a good chance that the hearts will provide a source of tricks.

Our weak twos are aggressive and are frequently on only a five-card suit especially not vulnerable. As you see we do not care too much about having a side four-card major that might dissuade others from a similar opening.

There are two keys to the above auction. Firstly we were able to set trumps at 3♠ and then responder was able to make an unusual jump to the five-level to ask for aces excluding the A.

As I mentioned above on the actual hands we settled in 6♠ both times. We picked up on the first hand when the opponents only bid game and tied the second board. In a qualifying match where we were already getting a maximum 25 VPs it turned out not to be necessary to bid either grand.

7 ♠ by North

Greg Aldridge and Debbie McLeod were the only pair in the final (six teams) of the Fullarton Teams to bid and make 7♠ on this deal. Some only reached the small slam and some failed in the grand.

After avoiding the 4-4 heart fit, which incidentally probably should also yield 13 tricks, declarer has to carefully time the play to come to thirteen tricks. West's double of 5♣ ensured a club lead. Then the correct sequence of plays involves ruffing three clubs in dummy. The key is to manage the entries back to the north hand to take the ruffs. At least two declarers failed when they ruffed diamonds twice (possibly after taking two pitches on the top diamonds) this failed when east disposed of the 8 on the third club ruff. It is easy to see that a 4-1 heart break will be a problem if the singleton heart can be discarded by a player with fewer than four clubs. This suggests that the heart entry should be used early. On this hand ruffing a diamond the first time and using the heart the second time would work but that would fail if the clubs were 6-2 and there is a suggestion that the clubs might not break after west's double although Livingston may have chosen to bid 2♣ or 3♣ earlier if she had six. The best play then is to return the first time to the north hand with a heart and use the diamond ruffs the next two times.

Also note that it is safest and best to save the AK until after trumps have been drawn. Playing them early leaves open the possibility that east will be able to over-ruff when north returns to hand with the third or fourth diamond.

6 ♠ by West

6♠ is an excellent contract and indeed double dummy can be made. However after two rounds of clubs forcing west to ruff the line to make is to cross to dummy and take a first round trump finesse for the ♠J and then bank everything on the very favourable diamond position. In practice the obvious and much better line of ruffing one more club and relying on a normal 3=2 trump division is how declarer should play this hand. Unfortunately as you can see that line fails on this particular layout.
