Orlando hand

Here is a deal that came up on the first day of the 2016 NABC Swiss Teams in Orlando.

*3C showed values.

Lead H9

It looks like 9 tricks should be attainable unless the opposing distribution is very unfriendly. With a club split or if spades come in for 4 tricks you make your contract.

You duck the first two hearts, on general principles, and win the third. East has KQJxxx and West pitches the diamond A on the third round of hearts! What's going on? Is West really squeezed?

Is LHO 4-2-2-5? You cash your top clubs in hand (ace-queen) and as expected East shows out (pithing a diamond). What now?

Seems like he's got something like

J x x x
9 x
A K
10 9 8 7 x

Declarer, an American pro, took that inference and continued with another diamond.
This was the full deal:

                     K 7
                     4 2

                     Q 10 7 6

                     K J 5 4 3

      9 8 4 2                J 5 3

      9 7                      K Q J 8 5 3

      A 8                     K 4 2

      10 9 8 7 2           6

                     A Q 10 6

                     A 10 5

                     J 9 5 3

                     A Q

I was sitting West (playing with Allan Falk). Maybe declarer should get it right but without my pitch 3NT was making easily.
