Thanks to all who answered my ignorant questions so kindly and clearly. What a great forum this is. I've learned so much about flying from you.
Lyman asked me a bunch of questions about what I think/assume, many posts ago. I was going to give him a detailed answer, but by simply being away from the computer for a while, the time has come and gone. Suffice to say, yes, I agree, there must be more to the story than what we have been told. And to your closing remark, "Four spades? Double," I simply say, "Redouble!"
