IMPs, head to head match. First segment of 4.

I watched one hand of the Spring Fours today and that was enough. The 2013 Spingold winner, Woijcech Gawel, playing for the Auken-Welland team against the Zia-Bilde team, showed poor technique on this hand. West led the six of diamonds to East's king and the eight of clubs was returned. Over to you,

It would seem odd if E had 7 clubs and overcalled 2, so going up with the ace guarantees the contract.

Is it likely W had KJ10xxx and presumably 4 diamonds and only bid 3 ? not very but possible.
Is it possible W had QJ10xxx and K and 4 diamonds ? not very, but just about
He could have WJOd presumably with the hearts

Are the chances of either of these this high enough that you want to give up the 1 IMP for the overtrick if the K is onside as is pretty likely ?

Early in the match I think I avoid the disaster and just rise with the A, draw trumps in as many rounds as necessary and play 3 rounds of hearts ruffing the fourth if I need to.

Cyberyeti's answer looks good to me. It's unlikely that West has 6 clubs but not out of the question, so why take the risk?

CYBERYETI on the money as usual. I rate west as around 18 times (I need a math major for this estimate) more likely to have 6 clubs than east having 7c. Even though the overall odds of west having said 6 clubs is tiny, I have zero problems letting go of the possible overtrick. I have no recollection of ever losing an imp match due to overtricks.

I've been involved in long board teams matches that have been decided by 1 IMP several times (including being on both ends of this in the same 48 board final in different years), we also failed to qualify for a national final by an IMP this year (multiple teams, we won the last match against the team we were competing with but by 1 IMP too few). I'm sure you could look back at overtricks in any of those.

team strategy: make contract first. match pair strategy: make contract but look for overtrick(s) at same time. Simple

Either you have a selective short memory, or you don't play many IMP matches.

So, what was the gaffe? Did declarer play the Ace and blow an overtrick or finesse and run into a 6-1 break?

I'm guessing what happened is the latter. The point being taking the finesse was an unnecessary risk. The contract is rock solid by rising with the ace (West will not have a void), taking the finesse risks going down on a club ruff when the lead is a singleton.

That is right. Declarer finessed and sustained a club ruff. I think it was a blind spot and he thought that he was still making for some reason.
