What is RHO's bid? Cannot bid 1D over 1D? ;-)
What's their NT range?
How many diamonds does 1D guarantee? If 3-3 in minors, they would open 1C?
4-4 minors to open 1D?

Sorry, the opening bid is 1C. 1NT is 15-17.

I am hoping D8 is doubleton. Win DA (pitching a club) and ruff a D,
eliminating W's D. Draw trumps, and play HQ to throw in W.

oh, playing HQ at trick 1 is such a fantastic play! I totally missed it.
It probably does not matter if W only has 2 Ds, but if he has 3, it seems
essential to throw HQ away to ensure communication at the ending.
After DA and a ruff, keep playing trumps to arrive at the following ending:
-
J85
x

Kx
Ax

Now play Hx, W cannot prevent your J from getting in to ruff the last D.
If you have HQx in hand, W can make sure you are stuck in your own hand by
ducking HQ, and he still has a D to exit.

Exactly. Ditching HQ creates a sure entry to dummy, which can be useful. It
doesn't really cost anything since dummy had HJ, unless west led from Axx,
which would be virtually impossible, and East's attitude card confirmed this.
However, if you keep drawing trumps, West will have the opportunity to
discarding HK!! If East started with T9x in hearts that will create an entry
for east. :-)
For the same reason, winning HJ to ruff 3rd D is actually dangerous, if West
indeed only had 2 diamonds. West can pitch HK on 3rd D. You have to read
the distribution correctly. Still, playing HQ at trick 1 is a nice effort.
If West started with exactly AK9 in hearts, this will eliminate the guess in
diamond distribution at the end.

Yep, just take a guess on diamond distribution. For example, if West has a
stiff spade, then it's more likely that he holds 3 diamonds; with 1-3-2-7
shape he might bid over 4S. On the other hand if West has 3 trumps, then the
chance of him holding only two diamonds becomes pretty high.

That might make a difference when West has a singleton diamond. It's not
likely but I don't see why we shouldn't do it.

I had thought it also makes difference if west has 3 diamond, in case he
ducks 2nd heart. We can then ruff one more diamond after entering dummy with
HJ.

Not really. You can win DA, ruff D, later go to dummy to ruff 3rd D if
necessary (but as I mentioned there could be cost if you guess wrong and
West started with 2 diamonds only). But in general it is sound technique to
ruff first diamond in hand. Sometimes it also gives you an option of what to
discard on DA in later play.

the most straight forward play is to ruff D, draw trumps then play H to J. H
has to be 3-3 if opps play UDCA( of course, some times opps may lead A from
Axxx and his partner happens to hold KT, which is very very rare.)
LHO has to duck HK, otherwise, you win 2H, 1D, 7 trumps.
so you win HJ, cash DA and ruff D again. now you can play H again to end
play LHO.
This line requires LHO to hold 2-3-3-5 or 3-3-3-4 shape to work. It also
works when LHO holds doubleton D, and H9, so he can't pitch HK to unblock
under your third D.

if LHO holds 1-3-2-7 or 1-3-3-6 shape, you are likely to go down if he holds
no H9. He can pitch HK on the second round of trumps.

Depending on the opponents. Against random opponents on BBO for example,
there is a good chance they couldn't find the unblocking play. Anyway I don'

not too difficult either. If east holds 5 or 6 diamonds with KQ, then he
should know that D is hopeless and declarer is almost marked with D shortage
. He has no C honor either. If partner holds a good sequence in C, he would
play C himself. So he really doesn't like C. If he doesn't like C and D, it
makes sense to encourage H here.
There are also some other holdings for H continuations. For example,
Declarer may hold
two H and a void D, in that case, D switch may help declarer to eliminate
one H loser. Declarer may false card Q from Qx and pray for a D witch to
pitch H and lose only two more tricks in S and C.

Maybe declarer is holding Qx in hearts and two diamonds, heart continuation
is the only way to allow the contract to make. Or declarer may have 7-2-1-3
shape, playing a diamond to knock out DA entry is important, otherwise
declarer pitches a club on HJ. When East holds something like 3-3-5-2 shape,
this can be the worry.
If East has KQJxx in diamonds and T9x in hearts, many would discourage to
get partner to switch to diamond. It is not always correct, but it's
somewhat normal.

I wasn't saying it's a clear play. However, in this situation, if declarer
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
's a reasonable gamble and a great play.
Another comment here is that even if you discourage in H, it's unclear that
D switch is the best. Suppose declarer hold AKQJxxxx Qxx - xx, D switch
would be fatal.
Therefore, HT can easily suggest a C switch for a cashing game. D works only
when you can knock out D entry for H pitches and no endplay issues. So
idealy, HT should work
when you expect a cashing game in C. For entry knock-out plays in D, it's
probably rare IMO and no signal system can really work on every layout.
Among all the possible plays, low H is still quite a nice attempt.

At one table, the declarer won second trick with DA, ruffed a D, two rounds
of trumps, and then H. At another table, the declarer ruffed D at second
trick. But he did not draw trumps at all (I don't understand why), instead
played a heart immediately. West won HK, and exited with with H9.
