Does the column line depend on West holding the 10S?
(instead, of, say, the 6S or 8S — after all, if S are 1 – 3 with the KS in East hand, the odds seem 2 to 1 that East would have the 10S instead of West))
If East over-ruffs the 9S with the 10S, then KD and a small D that declarer ruffs. Now what?
