I follow some matches of transnational championship.Some pairs use many systems of bidding different from usual common player. It would be more useful if commentator explain them instead of talk about plus and minus.

The commentators do often try to fill in these details, but it's hard to do it every time. And it's not always possible to find commentators who are familiar with the details of everyone's system.

If the auction confuses you, send a message to one of the commentators asking for an explanation, and they'll usually comment.
