Advantages
XY Notrump gives very good control finding both games and slams, as the final "mission" of the sequence is established at a relatively early stage of bidding.
Playing, as very common in combination with XY no trump, the Walsh convention or even Transfer Walsh, one still has the chance of stopping in 2♦ on weak hands, often impossible using for example Checkback Stayman.

Famous quotes containing the word advantages:
“When the manipulations of childhood are a little larceny, they may grow and change with the child into qualities useful and admire in the grown-up world. When they are the futile struggle for love and concern and protection, they may become the warped and ruthless machinations of adults who seek in the advantages of power what they could never win as children.”
—Leontine Young (20th century)
“No advantages in this world are pure and unmixed.”
—David Hume (1711–1776)
“There is no one thoroughly despicable. We cannot descend much lower than an idiot; and an idiot has some advantages over a wise man.”
—William Hazlitt (1778–1830)
