RHO opens 2NT, and LHO bids 7NT. You lead DT, and see the dummy:

Declarer wins with Q, continues DK and another D to his A, while partner
shows odd number of diamonds. What do you discard? | b***y
发帖数: 2804 | 2 就看庄家能否猜中HQ了吧。红心肯定不能垫。最好也不要垫黑桃，以免庄家算出牌型。
垫梅花应该没有大碍吧。庄家要是拿着AKQJx的梅花，总是可以挤住你。 | i****e
发帖数: 642 | 3 It is absolutely safe to discard a spade, in term of the suit itself, so we
may not care do discard one. However it gives away distribution information
once you discard on the third spade later.

When declarer cashes D and C, he will find you have 2D and 5C. If you show
you have only 3S, then you have exactly 3H. Then declarer can play H suit
without any guess.
The same for your partner. He needs to keep all his spades, and discard a D
on last C. This is easier for him, since D discard is safe, while you may
have the illusion to protect C in case declarer has AKQJx.
In other words, if both defenders won't show who has the last spade, it is
up to declarer's guess. Otherwise he can play H 100% right.
