Who's zooming who?

Went to Stockholm last week (on work) and did some practise with Frederic. We're going to Montegrotto in Italy next week and really need to get a lot of boards together.

One evening we practised against the new Open Team partnership of Cullin-Upmark. They got the nod for the 3rd spot on the Swedish team for the Bermuda Bowl this fall in Shanghai just a day earlier. They needed to be *roughed up* ;-)

I opened 2H showing 9-12 w/6+suit on AQx/QT87xx/Kx/Jx all white. Partner invited and I had to play 4H. Johan Upmark led a 3rd/5th diamond:

KTxx
Kxx
Txx
A9x

AQx
QT87xx
Kx
Jx

I covered with the T and ace to the right followed by club Queen (2nd/4th) after about a minute. Diamonds looked as 4-4. I took the ace immediately and played a spade to the ace with the 9 on my right (upside-down) and small to the left.
Heart to the 9-K-A followed by club and more clubs dropping the T to the left. Clubs looked 5-3 and I was sure spades wasn't 5-1 either way as no spade lead or trick 2 shift.

Not wanting to play for hearts to break immediately, I decided - after some thought, to play a spade to dummy first and lead hearts up. This resulted in J - K - x. There it was, the final clue - and I finessed in hearts to pick up Jx.

Johan knew it was about the trump suit and played spade J from Jx to look like 2-2-4-5 instead of 3-1-4-5. But, I "knew" that spades were 3-3 from the 9 played in trick 3 but couldn't be 100% sure about how the minor-suits broke. Therefore the J play, when I knew he had another one, was a sure "tell".
