so it appears that you want to play LHO to hold 2 H and Cxx, CJxx, CKxx, CJx

with CJ, you just take the success finesse in C and later play a squeeze in

If defence ducks CK, we could play a spade and plan to cross ruff S and H. |

发帖数: 20570 | 16 It appears that east shows 5 S + 4H, so it's usually a good idea to play a
simple squeeze against west in H and D. to reach that position, you need to
ruff 3 more spades.
So ruff S with CA.
C to C7,
ruff second S, with CK, suppose trump is 2-1 split.
J to CQ.
ruff the third S with CJ,
D to DK.
ruff the 4th S with C9.
ruff H to dummy.
Now play dummy's club and squeeze west in D and H. |

So RHO shows at least 6 spades. LHO didn't lead the obvious S. We can place
him to hold SAx or natural trump tricks like HKQx. D 3 is likely to be led
from three low D or 4 low D or QT3(2).

From the view of the declarer, 3D is safe unless there are *THREE*
heart losers (a heart ruff) or two heart losers plus a spade ruff.
Spade ruff is unlikely since East may open 3S instead of 2S if he
had serven cards of spades. If A and Q of hearts is behind the dummy
and East had only 1 or 2 cardsof hearts, Heart ruff is unavoidable.
It is important that East CANNOT have both A and Q of hearts. So HJ
will ALWAYS lose to West's HQ or HA. But HK may hold that trick. If so,

After SAK, play DA, then Dx to K (W would not ruff a loser);
Now play another D to E, discard a club;
If E returns HQ, play HA and then dummy's last D, discard another club, E is
now thrown in.
If E cashes D before returning H, we still discard clubs; later on ruff
dummy's clubs with small trumps. W can only win one trump trick.
If E keeps cashing D, we could ruff/sluff.
The point is W could not ruff our H loser. |

To make it, I have to win all the remaining 10 (5 top trumps and 5d).
Since
E discarded a D, I assume E does not have DQ - E not afraid DQ being
ruffed
out. I also assume E has few trumps (1 or 2) because of 3h bid. I don't
think I have enough entries to handle D 5-1 split (to finess/ruff out D
and
draw trumps). So I am going to play for makeable/likely distribution of

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

None of above.
Play righty having SA is reasonable, but before the ruff finesse, the timing

I think the correct line is, win DK, HA, heart ruff, then call a spade honor

SK
CA, C ruff.
SA,

现在西就被覆盖了.
上面这条路线在西2-3-4-4时可以保证成功.

A heart lead, down. Any other lead, this contract is cold according to this

However, the declarer made a mistake which defense let it through. In third

发帖数: 2168 | 38 I'd ruff the 2nd club, play a trump to HA, ruff another club using HJ.
If CQ drops, I am home;
If not, play another trump to HK and lead a small spade. If E plays low, I
play S9 to let W in.
If W does not have the 4th club, I am home;
If he has, I ruff again, play my last trump to HQ, and lead SJ.
Anyway, the idea is to avoid E to get in.
If during the play you figure out the club and heart distribution, you might
have more idea about how to play the spade. West is likely to have 5 or 6

After SK draws trump, play a C off table. If RHO starts with KQxxx, he may
duck, since otherwise it gives you a chance to set up a discards if you are
stiff. Then you can ruff finesse the DA to pitch C. And try to drop HQ for
overtrick.
If trump 3-1, since we can't ruff a H, it's not safe to try this line, so
fall back to knock out CK and ruff finesse D. |

In case of 5152, I like your route.
In case of 5251, there is another route: hoping to get 2S, 5H, 2 D ruffs and
3+ clubs. So you ruff the first trick, play SA, ruff another D, run CJ...
you only lose when E has single CQ.
Suppose RHO covers, you win, play HA and Hx to HJ, cash SK to pitch D, and

Returning H8 at trick 2 will ensure -2, and prevents accident.

Now we should be in good shape to ruff another D, clear trumps, and play H. |
