"The one-club sequences are powerful. Transfer auctions are valuable because they allow the partnership an extra step to exchange more information. Responder knows the extent of a major-suit fit very early in the auction. And finally, it can be difficult to defend accurately against a one club opener because the normal distributional clues that the defenders have in standard bidding may be absent."
ACBL Bridge Bulletin (March 2021)Toucan is a modified 2/1 system using a natural but short club opening with transfer responses to it. Toucan Club Complete is a much-expanded version of the original Toucan Club book, and contains many example hands and auctions.
