Most excellent!!!
Yes, this hand looks deceptionally easy. A simple vienna coup squeeze, involving pitching a diamond on the heart ACE, Pull one round of trumps just in case you miscounted when you counted up to 13 (safety play for bad counters), Cash club ACE (vienna coup), then run the trumps, coming too...
This vienna coup stands out as very obvious, requiring only that the vulnerable 5
♦ preempter over 1NT opening bid has the expected 7 diamonds (I would think he needs 8 diamonds, but alas we have 6 of them ourselves), or even if he bid this with only 6 diamonds (giving West a stingleton) and the club king.
And indeed, the vienna coup wins. But a huge kudos to Fluffy who saw through the obvious to a not quite as obvious line. The criss-cross squeeze she envisions works even if EAST happens to have only 5 diamonds. This is a marked improvelment. Imagine a "clever" East extrapolating a red two suited overcall from teh two level up all the way to the five level (where re all those hearts?). If East happens to have 5H and 5D, the vienna squeeze will not work, as WEST can keep his two diamonds. Fluffy's line works when the vienna coup works, but also in this ending (west wtih 2 diamonds)
So full credit to Flame for the 99.9999% sure vienna coup, and full credit plus extra credit to Fluffy for looking really deeply into this problem. West was void in diamonds, as expected. Full hand....
1NT - (5♦) - 5♠ - (6♥)
6♠ - (7♥) - 7♠ - all pass
