- If opener shows a four-card major, raise it.
- If opener bids a negative 2♦, bid the shorter major at the three-level.
Opener's rebids after the transfer bid Edit
After responder bids a 3-level major (over 2♦), opener may:
- Accept the transfer by raising the long major suit
- Deny the transfer by bidding 3NT with a doubleton.
- Bypass the transfer by bidding 4♣ to show a maximum and a good fit.
- With a six-card major, responder may retransfer by bidding the suit directly below the intended game bid.
Thus, 1NT-2♣-2♦-3♥-3♠ or 1NT-2♣-2♦-3♠-4♥ are accepted transfers.
One complaint with Smolen transfers is that it is impossible to show an invitational 5-4 hand (at least in hearts). With four suit transfers, the minor suit rebids after Stayman are less important and therefore Quest transfers allow invites by exchanging 3♠ with 3♦ as a transfer to hearts.
Note: Some bid the shorter major at the two level for those opening 1NT with a 5 card major. Responder with 4-3 in the majors and game going values can use the three level to bid the shorter major. Either a 4-4 or 5-3 fit can be found this way.
