Playing in a teams contest, games are bid aggressively and not a few of them require good play. In this hand, East opened a weak 1NT and South’s interference removed any science from the auction. West doubled to bring both majors into consideration and, when East showed the heart suit, West bid the game. Since the spade and diamond suits are not attractive, the lead seems to be a trump or club and one might avoid the club since the 1NT bidder is more likely to hold the KC. After a trump lead, the contract is easy to make as the cards lie, losing only one club and two spades. As it happens, the AC lead is much more dynamic. Since everyone can see the KC on table, partner will signal natural count rather than attitude. It is easy to continue with the QC to the king and a ruff. Looking at dummy, it is clear to switch to a small spade ( promising an honour) and declarer will rise with the ace. It is difficult to see where ten tricks can be made while avoiding two spade losers.
For there not to be two spade losers, the suit needs to be blocked and South needs to be stripped of all red cards before being endplayed. Thus, declarer needs to play AD, trump to hand, diamond ruff, draw last trump, ruff a club, and exit a spade. Then when South wins the KS, he has only clubs left and dummy can ruff while declarer sheds the last spade. While the line of play might seem difficult to find, it is forced upon declarer by the need to avoid losing two spades. There are two more wrinkles though. The defenders can beat this line if South can manage to play the KS under the AS so that North can win two spade tricks when declarer tries the spade exit. Further, if South misses this chance, declarer must not play the QD and ruff a diamond before exiting with a spade because South gets two more chances to dispose of the KS before it embarrasses him! Disposing of the KS needs South to realize that contract can only be defeated if North has the SQ10.
