Once you discover the magic of Jacoby Transfer Bids, it's hard to give them up!
By default, Jacoby Transfers are OFF when the opponents interfere with any bid other than 2♣. The Stayman convention has long specified that after an interfering 2♣ bid a double (X) is used to ask partner for a 4-card major suit.
Why not do the same for all of the other intervening bids as well? 1NT - 2♦ - X as a transfer to hearts, 1NT - 2♥ - X as a transfer to spades, 1NT - 2♠ - X as a relay to the minors.
The "stolen bid double" caught on like wildfire, especially among intermediate players. As I began playing with more experienced partners, I discovered that none of them used the stolen bid double!
