Practice bidding Standard American Yellow Card (SAYC). This bridge app is available for install on Android and Chrome.
The autobidder is designed to follow the official
 ACBL pamphlet
 as well as the excellent Standard Bidding With SAYC
 by Ned Downey
 and Ellen Pomer.
Improvements are made to the autobidder regularly. Although constructive bidding works well, competitive bidding (and especially slam bidding) need improvement.
