It was the last deal of a 6D shoe. The count was monsterous. It was late and I was going to finally get to use my "Hale Mary" or "Grand Slam" act for a last giant spread of a bet before retiring to my room. I wanted to place a bet in all seven positions. I asked. The dealer said "why". I decided to just put it all on three positions. I placed 25 units on each circle and did a little dance, a table pat/rub, etc. for good luck. I was now standing up. Cards came. I had good hands 19's and 20's. Dealer turns an ace. I made some exclamation and quickly turned my back and made some little curse as I did sort of a full circle. I looked back and the dealer started to turn over the hole card. I quickly said "wait! I think I want to take insurance." The hole card had partially flipped up. I thought he saw it. I didn't see it. He said, "do you want insurance" and winked. I thought for a moment and took the wink as if not to buy it. He flipped it and it was a BJ. I called for the pit and got nothing in return.
I learned a lesson on that one to be quick to not allow them to turn the hole card too soon. I still don't know what the wink really meant.
