*Title is same as that of book by Mike Lawrence
Here is an interesting hand in which Mike Lawrence shares his thinking. Mike is sitting South.
The transfer did not get accepted after the lead directing double because (by partnership agreement) North held fewer than three spades. Mike decided to bid game with the known 8-card fit.
Opening lead was the seven of diamonds, and East won with the ace. What diamond did Mike play from hand at trick one and why does it matter?
Tackle this question first in the comments, and I then will have more insights from Mike Lawrence on this particular hand.
