On board 8 of the England-Italy Open final, some commentators called board 8 a "cold slam" and "South dropped the ball":

The 2H opening was 10-13 or a great 9. The commentators, looking at all four hands, can see, in 6 Clubs, 1 heart loser and no club loser by picking up the clubs - however will that happen? With only 13 high card points out declarer can reasonably play clubs to be 2-2, and the "cold slam" is down 1, just like it was in the Japan-US match when Japan was NS. It's important to always consider bridge hands from declarer's viewpoint, not just the double dummy "can see all four hands" possibilities. Likewise here 6 Spades is a better contract than 6 Clubs (club loser can be eliminated by ruffing the third round of clubs), but can North-South arrange to play in their 8 card fit instead of their 9 card fit? Here, instead of "dropping the ball" I think the Hacketts did well.
