Possible ending:
squeeze west if he has 4+ clubs (less likely);
finesse east if west has CJx or Tx (more likely).

Need to figure out west's shape. S2 should be an honest singleton. HKQ, both
follow?

If east follows H9 on first trump, trust it if he is novice, ignore it if he
is expert :)

西家在有局第一家的情况下开叫2S,应该是6张黑桃。并且不太可能有四张红心。

你兑现HKQ,西家第二轮告缺。然后呢?

Expert也不太可能从J9xx里出9。同伴可能是单张10。

This is kind of expected. Clear trump, and diamonds. West follows 3 diamonds?

That will be the only headache, since he may have 6142 with CJx or Tx, he
may also have 6133 with CJTx. The restricted choice may apply here.

Right. Without seeing HT, H9 may backfire.

Can you guarantee the contract when West has either 6142 or 6133, even if
West has no CJ or C10?

Yes, but only after you told me so :) Not only for 6142 or 6133, but 100%
for west with any 61??

After two rounds of trumps, cash two diamonds (west has 6- D, so east can't
ruff). If west shows out, he will be squeezed in S and C. So let's say west
follows 2D. Then he has 4- C, so it is safe to cash a club. If west shows
out, we can ruff 4th C. Otherwise it is safe to cash last D. If west has 3+
D, he has 3- clubs, so it is safe to cash 3 clubs, and ruff last club at
dummy if needed.

Interesting hand!

I might have figured out this play if you changed C9 to small C :)

A correction: cash only 1 D before cashing a C. This will keep the D entry
in case west has unlikely 6160.

Yes. 100% line. :-)

Of course no one will tell you at the table, you have to figure that out. :-
) This is an example of so-called "discovery play".

The previous posts may be messy, and let me recap the interesting play for
this 6H.

Once we know west has 6 spades and singleton trump, 6H is 100% safe.
If anytime we find west has 2 or less diamonds, we can squeeze west in S and
C.
If anytime we find west has 2 or less clubs, we can ruff 4th club at dummy.

So all we need is to explore west's shape without risking ruff by east. The
100% line is as following (after SA and HKQ):
DA
CK
DKQ
CQ
Finesse trump
CA

This supposes west always follows suit, otherwise we take one of the above
two lines.
