I sure opened up something. Where we play 1nt-2♠means to transfer to clubs. 1nt -♣means to transfer to diamonds. Just like the opp who thought everyone knew what a limit raise is. As far as reading the rules, no i don't spend time doing that but when there is a change , as i was told, it should be announced. Right after i posted my comment, there was an email from acbl speaksy. That explained it. It would be nice if that was always the case in a change. Tks for your comments.
