Update by Saskia Hermans Feb 16, 2017
Currently the themes in uBasic are excellent for bridge starters and players wanting to improve their elementary bidding. The hints & explanations in uBasic are based on 4-crd major and strong 2, popular in many countries for new players.
Because most players transfer to a bidding system, based on a 5-crd major after a few years, a special theme ‘migrating from 4- to 5-crd major’ has been developed.
Soon a new theme will be part of uBasic, especially for those being taught 5-crd major from the beginning. In that case, it can be used by all new players.
I hope you will enjoy the new themes!
