If both opps follow on 3rd C. We now play S6, cover whatever west plays.
East is endplayed. East could cash last C if he has it (dummy discard
D), and then has to return S or D, which gives 10th trick.
If west has 5 C, east will be endplayed after we play S. If east has 5
C, we play C8 (dummy discards S) to throw into him. He can cash one
more club and we discard S6 from ha... 阅读全帖 |

to take HA, try D, he'd duck one D, then I'll play the second D, drive out

H9, try a club to CJ, east has to duck to create any problems, then I cash

发帖数: 679 | 3 I am sure there is a better line out there. But I would play as follows.
Draw trumps (keeping trump K); Cash H AK; exit C;
- if W wins, the contract becomes cold (at best W plays another C, S then
discards H; W canot avoid being endplayed when E switches to D).
- if E wins, E has to switch to D (if C, S discards H, W canot avoid being
endplayed); assuming W wins and switches back to C; if E has CK, declarer
ruffs and plays H. Now if H is 3-3 or Q in W hand, declarer can still get
the 10th trick ... 阅读全帖 |

Now we already know whether west has any 4+ cards in H D or C. If he doesn't
have any 4+ suit beside S, we cash all H D C winners, and endplay west in S
if needed.
If west has 4+ C, we cash two red Qs, and at 4-card ending, he will have
either SJTx Cx or SJT Cxx. For the former, we strip his C, and endplay him
with S. For latter, we set up a S.
If west has a 4+ red s... 阅读全帖 |

发帖数: 31 | 8 Interesting hand, east is squeezed in 3 suits.
(1) pitch a spade, ended up the actual play
(2) pitch a diamond, you can cash Club and exit with a club to endplay him
(3) pitch a club, even worse.
His partner could helped him by not pitching clubs when you cash diamond.
But the opening lead look really like a 4th best.
Nice played! |

发帖数: 623 | 9 It seems the only way to make this is to take a dummy
reversal -- taking 3 ruffs -- and then endplay South in D.
So 3D + 6 trumps. Defenders probably fell from grace by
trying to take a forcing game. |

发帖数: 623 | 11 In that case he doesn't have to endplay you: he can set up a S and a C pitch.
I think the best chance is to play partner for DQ so switch to a low D. If he
has CK instead, the trick you blow may be immaterial anyway as you still have
control in S, the only thing he can set up for pitch.
Occasionally it's right to find pd's ruff. In many cases the declarer blasted
to game not due to the strength, rather due to the 2nd suit. But either of the
black suits will be fairly weak so chances are, if he h |

发帖数: 623 | 12 Play suggests that west has 4-3-3-3 shape and she was thinking of overruffing
but was afraid of getting endplayed afterwards.
So play 3 rounds of C, ruff in dummy and exit with a H and hope west leads to
your SAT. |

发帖数: 623 | 13 A D lead would break up the endplay in D and. When East gets in 1st time, he
can simply play DJ to knockout the DA. When get in second time, E can cash
trump (so south cannot ruff C) and cash D, and give E a D ruff if the D8's in
south's hand. NS can get no more than 3S, 2C, and 2D. |

发帖数: 623 | 15 I'm probably wrong here. It looks East can keep leading D and give west a D

Now the D contract by North looks attracting. 8 tricks might be possible --
the best East can do is to lead DK and then DJ, but East will be endplayed
twice then.

发帖数: 623 | 17 Looks easy, you either have to bring in the C, or try for a strip squeeze
against E, when he has to protect both C and S. You run D to find out possible
distribution of E 1st.
If west shows more than 1D, then you come to the ending
- x - AQTx vs Ax KJ x. East will have to keep 2S and 3C so he can't keep any
H, and you endplay him with a S.
The worst case is when west shows a total of 3 cards in S and D, then you need
to guess whether he bid H with 7 or 8 cards.

发帖数: 3277 | 18 play low. If you play high and return C, the defense is effective only
when LHO holds QJxx xx AJxx KJxx, in that case, he'd open 1C for sure.
Declarer may hold Qxxxx xx AJ KJxx, in that case you have to play low
otherwise, you may crash partner's SJ, which is your setting trick.
And you can't blame partner not to play SJ after SA, cause partner
may think her SJ can score a trick if declarer holds SKQ9xx.
Also, you don't need to worry about endplays, cause dummy also holds
3 spades.

a case, splitting HQJ will be fatal. |

发帖数: 679 | 23 It seems not too difficult if just to play for make.
- 3 rounds of S;
- play C (unblocking J from hand) to endplay E;
- dummy has 2 entries, hA and cT, to finess dA and later to cash 1d;
so you will get 6s,2h,1d and 3c for 12 tricks |

win SK, play CA, and low C to C9, if east holds CKx, he would be thrown in

returns Dx, you cover west's DT or J, cash clubs and pay attention to east
pitches to end play east again. If east returns DT or DJ or even DK, you can
allow him to win and win D later.

发帖数: 20570 | 28 You still didn't realize how dangerous 2C can be.
Suppose the bidding goes like: 1D 2C 2H 2S:
Now you show 4S +5C, you partner holds Ax xxxx AQJx QJx
so he bids 3C to set up trumps. Now you have a problem, your 3D only shows 3

Anyway, you bid 3D. Now your partner knows that his H holding is weak. So he
bids 3S as a cuebid.
Now what? 4C is waiting. 4D is RKC in C, you are endplayed. Still, you are
smart, so you just bid 6D to end this nonsense. However, your partner is
also smart. You jump to... 阅读全帖 |

发帖数: 2804 | 29 In reality, the preempter holds HAQ, SQJ, CQ. But basically just need HQ on side, then declarer can eliminate spades and diamonds, and play a small club from dummy to endplay the opponents (note how important C8 is).
You can definitely construct hands where 4H or even 3H has no chance. You can also say that these expert players are very undisciplined. But the fact still remains, that "they" win much more games than we do.
Also note that this is not really a perfect "magic hand": the mirror shape... 阅读全帖 |

You couldn't even provide any bridge argument on why you have to bid 4H with
an 8 losers hand when your partner only shows an invitational or better
hand without a lot of distributions. Yet, you catch a really good hand to
fit your DQxx, HKT9x and CJ9xx to have a less than 50% game, which can be
made in the real layout. If you do a simulation to give your RHO a hand with
6 good spades, less than 10 HCP and often some dist... 阅读全帖 |

发帖数: 20570 | 31 This line is very strange. Suppose partner's signal is real, he must hold 3
spades because he plays trump echo. Therefore, declarer holds only 5 spades,
perhaps something like KJTxx xx Axxx xx. Partner's D8 has to show some
interest in D. The safest return now is certainly H. because declarer may
have some problems return to hand. D return is also usually safe, unless
partner signals D8 from 8x. Even if that's the case, I don't think it
matters because it's also cold. One interesting case is th... 阅读全帖 |

is very likely to hold a shortness and you hold 5 or more diamonds, then
declarer usually has D shortness. Based on this guess, it's normal to
encourage H. If declarer holds 2H + 1D, D switch shouldn't work in many
layouts because declarer can ruff one D and end play partner later with a
lot of good club holdings like AJx, KQT.
Basically, if my partner can find this defensive play, I would really say it

He lead SJ, a bad choice in my opinion, but it is not the end of the defense
. Declarer won with SQ. A low diamond was led from dummy. Pard played DJ,
and declarer DA. Isn't is obvious that pard is playing from JTx or JT?
He did not drop DQ. That is the second mistake. Declarer play another D, and
