This is a link to the whole hand from a Frank Stewart column:
E-W vulnerable, S bid 1 spade, raised to 2 spades by N. All pass.
West opened with the king of hearts. Dummy, East and South played low with the 3,5, and 8 respectively. At this point, West knows that the outstanding cards are QJT.
West failed to continue hearts (and let the contract make) because he was discouraged by the 5. But I would have read it as a singleton and continued hearts on the theory that if East had a Q, J, or T, he would have played that card as encouragement.
Should one not be discouraged by the 5 in this situation?
Would East discourage with exactly JT5 and play the 5? And even so, shouldn't West then continue with the A to drop South's Q?
