ASTRO - Interference Over a Bid of 1NT

From Club Director Raj comes this article about ASTRO,  This month I am listing a variety of ways to interfere with a 1 NT opener. See more at Bridge Bum ( Astro Bridge Convention - Bidding and Responses ) . A brief explanation of ASTRO follows. We intend to feature new Bridge items each week.

If you were to go back in time to the beginning of the universe and rearrange a deck of cards into a new permutation every second, the universe itself would come to an end before you were a billionth of a way to one of those arrangements repeating itself. As for how many atoms there are on the planet, most estimates put the number at 1.3 x 10 to the 50th power or 130,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. This is obviousl...
