I am showing the full hand as the best line should not be influenced by where the cards are.
My plan was to win the spade on the board, hook in hearts, cash AK of diamonds (looking for Q drop since diamonds were longer than clubs) then run it is a a minor suit show up squeeze (or hook if the count was right). Does that seem reasonable? It doesn't work here.
However, the comments from opps distracted me a little, as did my kid waking up in the next room. I smoothly unblocked the spade K from my hand under the A at trick 1 ( but didn't realize until diamond AK were cashed -- then it was too late to attempt to recover. I needed a diamond hook to work at that point once I lost a natural spade trick.)
Two questions:
1) Suppose you, for some strange reason, did NOT want to "unblock" the spade K at trick one under the A. What is your planned line?
2) What if you decided to actually play the spade K under the A for a challenge -- like I did. What would your line be?
thanks,
fritz

(1) Jacoby 2NT
(2) 16-17 no singleton -- supposedly
(3) tank 1 minute counting tricks. I wrote "think". Opps message "hurry up or I'll call director" Figured better than 70% chance of taking all tricks, but should probably be in 7H to be safe at IMPS.
