发帖数: 642 | 5 That is the better chance I see. It is close to desperate :)
Anyway, it won't hurt to cash some C winners before playing west for stiff
HJ or Q. If west holds stiff or void in C, the chance of stiff HQ or J is
almost gone.
To be a little specific, if west has 3 or more C, I would simply play west
for stiff HQ or J. Otherwise, the hand is almost dead. I will try to play
west for starting with 5 S (or he discarded one on C), exit with S, and hope
for some miracle.

发帖数: 2804 | 6 Considering the bidding, chance for LHO to have only 5 spades is not that
low. Against average defenders it might be best to cash clubs then exit with
a spade, if you believe it is 5-3 split. When LHO cashes last spade, RHO
will be squeezed, if he holds HQJ and DKQ.
But with strong defenders, this probably won't work. LHO can win the spade
exit and switch to a diamond immediately.

However if he holds SAKxxxx HJx DQx Cxxx, he may discard a spade by mistake.
But I still don't see the chance except stiff HQ or J.
Then he will discard a heart on last club.

发帖数: 2804 | 20 Best play will go down, wrong play (with lucky guess) will make.
LHO cashes 3 spades (keep last spade un-cashed) and exit with a heart. RHO
pitches 1 diamond and 1 heart, with 5 cards left: HQJ, DKQT. Now double-
dummy, declarer can just play hearts and score H10. But declarer has no idea
that LHO started with 4 hearts. He more likely will play LHO for 6313 shape
, that would leave RHO with HQJx and DKQ. So he wins HA in hand, plays DA
and another D, trying to establish his DJ. Lights out!
Still, as I said, it would be nice try. At least declarer has given himself
a decent chance to make. It's just that, defenders still could give declarer
a guess in the final ending, and declarer would be more likely making the
wrong guess than the right one. Also, if RHO wrongly pitched 2 diamonds
instead of 1D and 1H, declarer will always make now.

发帖数: 524 | 21 I think you missed the mark.
After discarding a spade, if west saw the danger of suicide squeeze, with
6313 shape, the best defense is only to cash TWO spades, and switch to
diamond, then declarer has NO chance.
West didn't switch to diamond because he didn't have any.

发帖数: 2804 | 22 Hmm, if West is thinking so deep at the table, probably he can also figure
out that this defense doesn't help.
Let's suppose West does start with 6313 shape. After West cashes TWO spades,
there are 6 cards left at the table.
Dummy has: H Kx, D AJ9x
Declarer has: H AT8x, D 76
East probably has: H QJx D KQT
So how can switching to diamond help (even if West has one)? Declarer can
simply duck the diamond, win heart return in hand, play DA and another
diamond, setting up DJ for 9th trick. Therefore, declarer cannot really take
much inference in West's failure to switch to a diamond.
So this is pretty much a squeeze without count. As long as declarer reads
the shape correctly, there is no way to break it (after the spade pitch).
But there are still chances that declarer may not read the shape right.
The point is, as the defender, don't despair in this situation, try to leave
room for declarer to go wrong. If West cashes last spade, then it becomes
automatic squeeze with perfect count adjusted, defense would have had zero
chance.

发帖数: 524 | 23 Right, there's no defense anyway.
But had west had 3 little hearts, he could have found the heart discard on
clubs. Also, holding 4-4 in red suits, East might have chosen to discard a
heart first.
More importantly, after cashing 3 rounds of spades, it is simply wrong for
east to leave diamond unguarded (H QJx D KQ), isn't it?

发帖数: 2804 | 24 Yes, those are all true. Correct defense is for East to pitch down to HQJ
and DKQx. East has to hope that West holds H10.
At the table it may not be so simple. 6-4-0-3 is slightly less likely than 6
-3-1-3 for 2S opening, and East may have made a technical error by holding
onto HQJx and DKQ (which is a very common mistake, even good players might
occasionally make that one). On the other hand, if West didn't cash the last
spade, it indicates that West had nothing in hearts, then declarer should
ask himself why did West choose to pitch a spade on 4th club.
So I now agree that if declarer thinks it through, he should get it right.
But it requires some pretty deep thinking.

发帖数: 2804 | 25 All these discussions are probably academic though. If West cannot even work
out to keep all the spades, he mostly likely cannot work out the need to
break the squeeze. How can a heart pitch ever cost, other than a possible
over-trick for declarer? | p******e
发帖数: 1151 | 26 this is indeed an interesting hand
Are you that "Arrows" on BBO? Your image is very cool.
In reality (for me), I might first cash the club suit with desperate feeling
. The example did teach me a lesson that "never give up on board".
It seems easier to say that than having that faith in your belief though. |
