Declarer plays HQ, and you duck, while pd follows 5.
Declarer continues with HK. Do you duck again, or win it? Any thought for
the picture? | j*******e
发帖数: 2168 | 2 I can easily construct hands where ducking would be wrong: HK could very
well be declarer's 9th trick, e.g. he holds Axx/KQ9/xxx/AKxx
So I would just win.

发帖数: 642 | 3 Okay. Win HA, and pd pitches S8, which is likely from 8x remaining, so you
can't return S. If the hand is like your example, you will return DJ, or
something else?

Of course, I can also construct hands where returning C would be right after
winning H...

发帖数: 642 | 5 Yes, there are too many uncertainties. One important clue may be declarer's
choice of 3NT instead of 4H. With ATx KQ9 xxx AKxx, we can't say it is wrong
to play 3NT, but I would choose 4H.

发帖数: 2168 | 6 OK, how about this holding then: ATx KQ Kxxx KJxx
If you duck, declarer simply gets 2S2H2D3C for 9 tricks.

发帖数: 642 | 7 Yes, winning 2nd heart should be good. It not only prevents declarer from
stealing the 9th trick, but also it also keeps the possibility to exit with
a heart. When you see pd's S8 on HA, do you plan to attach D or C, or choose
passive defense by exiting with 4th heart?

发帖数: 2168 | 8 By the same logic, passive defense (exiting with 4th H) would give declarer
the 9th trick (and also the 10th) in certain layout.

发帖数: 642 | 11 You are right. I forget the dummy holding :)
But when you win HA, pd pitches S8. So declarer actually holds KQ9 for
hearts, but still chooses to play 3NT. How will you continue?
We now know declarer's majors holding:
ATx
KQ9

发帖数: 2168 | 12 If pd has CA, you can simply return C for him to switch to S;
if declarer has CA but not J, you should still return C;
if declarer has CAJ, seems we do not have chance.
So, return C.
