This is a very interesting and instructive hand. There are several things to consider. My first instinct was to assume if spades were 5 –1, West would hold them. In that case, 7C can ALWAYS be made. The line of play is this. Win the opening lead and play 3 more rounds of trump. Now, play Spade K and a spade to the Ace If west shows out, you need East to hold something good in diamonds to execute the simple squeeze. If East shows out, he is now the SOLE guard of one of the red suits, Since West only has 4 red cards, he cannot guard both red suits. So, if as declarer, you believe West cannot guard diamonds (likely), the sequence is Spade Q, Spade J, Diamond A, Diamond K, and last club, executing the simultaneous double squeeze. If, however, you believe West can no longer guard hearts., the sequence is Diamond A, last club, Heart A (squeezing West in diamonds and spades), Spade Q, Spade J, (squeezing East in hearts and diamonds), completing the sequential double squeeze. A very cute Compound Squeeze. The play, however, of cashing the Heart A and running clubs is far superior. It wins whenever the Heart K is with the long spades, or when the long spades have the diamond length. It also has the advantage that if East has the Heart K, the contract can ALWAYS be made, regardless of the remaining distribution. The play would go, win the lead, cash Heart A, run 3 more clubs. After 5 tricks, if East holds the Heart K, he can no longer guard both diamonds and spades. If he has 5 spades plus the Heart K, he can only have 2 diamonds, and if he holds 3 diamonds, he can have at most 4 spades. Admittedly, it is a guess as to his holding, but dummy’s extra spade winners allow us to play the last club, putting pressure on both East and West. Declarer should have a good chance on determining the pointed suit East still holds. If spades, the sequence is Diamond A, Diamond K, executing the simple squeeze. If he believes East to hold diamonds, the sequence is Spade K, Spade A, Spade Q, Spade J, completing the sequential double squeeze (West would have been squeezed on the last club). The advantage of this line of play is that declarer retains more options in the end game. It also preserves the squeeze positions when the Heart K is with the long spades, and also when with the diamond guard. The only time it fails( providing declarer reads the position) is when East has the spades, and West holds the Heart K and a diamond guard Just my thoughts.
