Wbridge5 is a prominent bridge program. Wbridge5 has been world champion of the bridge programs in 2005, 2007, 2008, and 2016–2018. Besides excellent playing, this program also employs a dedicated bidding system. I dream of human pairs using a bidding system like Wbridge5, so I collate the bidding system in this book.
The topic of this book is mainly bidding because playing is somewhat universal. Playing depends not on how to bid but on meaning of every call. There are so many experts and books for playing that writing one more book is infeasible for me.
Wbridge5 has a 2/1 bidding system with French flavors, as it originates from France. It incorporates some French conventions which improve bidding structure from Standard American. Others French conventions are not included in Wbridge5.
