Poor East. He picks up KJ10x QJxx x xxxx, and things start well for him: he gets to make a negative double of 1♦, showing most of his shape in one go. Then partner bids a game-forcing 2♦, which is nice, especially as responder has another easy call with 3♣. Now opener bids 3♦, presumably asking for a diamond stop. East has a fair hand for the bidding so far - four-card support and a singleton diamond, opposite what appears to be weak length. Still, he knows his partner is a bit of an overbidder, so instead of 4♦, which his hand is worth, he jumps to 5♣ to try to slow things down a bit. Then partner self-raises to 6♣ anyway. That drifts a couple off after a spade to the ace and a heart return, but maybe it doesn't matter - 5♣ might have gone down on the same defence. Then somebody wonders whether 3NT might have made.
In another world, East has AKxx Qxxx x xxxx, and sees the same pleasant start to the auction, but after 3♣ opener bids 3♥, which presumably sets hearts as trumps. East's hand has plusses and minuses, but it seems reasonable to bid 3♠. Over that, opener bids a serious 4♣. The weak clubs are a slight worry, but slam is good opposite x AKxx xxx AKQxx, and we're still below game, so East cue-bids 4♦. Now opener bids Keycard and follows with 6♣. Luckily East knows that that's a place to play not a grand-slam try, so he passes. Sadly, the trumps don't come in for no loser, and 6♣ goes down again. Then somebody wonders whether 3NT might have made.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn
