I finesse except in a game so weak I think there is any chance people have missed slam (I find 6♣ very unlikely since it will mostly go essentially 2NT - 6NT). Um, I will get a better score over 70% of the time, you don't often have that knowledge for sure about a play, it's a total waste not to take advantage! In any game that isn't very weak you are simply throwing away matchpoints if you don't finesse.
That's why I asked who was dealer. East was dealer, he opened 1
♣, thus I expect more pairs to have a misunderstanding, or to end up in 6
♣ or 7
♣. I would argue that with East as dealer there is a stronger case for taking the plus.
Anyway, I think a much more interesting question would be whether South or North gave anything away with their discards (and the timing of their discards). Unless we are playing the leader of the event, I find it unlikely that the game is weak enough to play the ace, and our opponents strong enough not to give anything away.
6NT by WEST
Opening lead helpful ♦K
You win 1D, 3S, 1H and 6C coming to the following ending (north is proven to have started with precisely 3♠-2♥-6♦-2♣, while south had 4♠-5♥-1♦-3♣
