See two posts ago for the problem.
The club pitch strongly implies that lefty was 2-4-2-5, so the ending looks something like:
N: --- AJ7 --- Q9x
W: --- ??? --- JTx E: Tx ?? 75 ----
S: ---- Tx 82 Kx
If West has both heart honors, you can make it by straightforward play. If East has the K, you can’t make it – the position is frustratingly close to a double squeeze, but there just isn’t a way to rectify the count without East cashing the setting trick. What if West has the K and East the Q? That is how it was at the table. If you cash the D8 now, at trick 8, West has three losing options. A club pitch is obviously no good. A low heart pitch lets you set up hearts while keeping East off lead, by a standard avoidance play. So should he pitch the HK? Then you cash the Q and K of clubs to execute a standard strip-squeeze against East (who must pitch his spade winners and get endplayed or bare the HQ.)
The catch? Suppose West pitches the HK, then when you cash your clubs East pitches a spade and a heart. So East just bared the HQ, right? Maybe. But maybe West has made a genius *fake* unblock holding both heart honors, and East has alertly cooperated (if he threw his spade winners from his entryless hand you would give him a diamond and claim.) I say if they do this to you, gracefully go one down, write the hand down carefully and you get to be the journalist for the Defense of the Year.
By the way, it is tempting to cash the CK first in the 6-card ending, to check the break. But then West can pitch the HK from K-empty and beat you, because you no longer have an endplay threat against East.
