In competitive bidding you are often short of bids to express all the necessary information. Transfers are a remedy to this problem. An advantage of a transfer bids by responder, after intervention, is that the opener can become declarer. With a weak hand, responder may pass after partner has accepted the transfer. He may also invite a game or force to game. There are other advantages, which I describe in the book. These are the main topics:

Transfers after a one-level overcall

Transfers after a Michaels cue bid

Transfers after partner's overcall followed by a one-level response

Peculiar transfer to 1NT

Transfers after partner's 1NT opening is overcalled

Transfers after 1♣/◊ openings and an opponent's overcall showing both majors

Defence against a preemptive 3♣ opening

Defence against a preemptive 3♥ opening
