I'm a new member; I know the bridge laws in the UK - I'm only interested in BBO procedures (in the absence of a user guide). Solo bridge (e.g. Game4) as practice is no use - in 3NT, with 5 tricks left and 6 from-the-top winners, I claim - and get a message asking if I wish to concede the remaining tricks, so I have to tediously play out the hand. In competition (I had my first go last night) what happens when you press the 'Claim' button ? Does the software then ask you to declare the intended line of play ? I had one claim made by the oppos, and saw no evidence that they'd provided a line of play. If it's not made compulsory by the software, can one insist (and if so, how?) on the oppos providing a line of play? If your rejection or non-immediate acceptance possibly leads (you suspect) to declarer being alerted to a problem and changing his play (the outstanding trump is the obvious example), what happens then - call the director? To me, it would make sense if declarer indicated his line of play then claimed so that he was committed before defenders had to reject/accept/ask- but this doesn't appear to be how it works. Basically, I just want to know how claiming works in BBO games (until then, I'll avoid it; but my first impression is that a lot of the time that could be spent thinking is spent on pointlessly playing out the final tricks; I'm talking about local club-level bridge, nothing fancy.)
