It then transpired that, allegedly, I'd claimed not for all the remaining tricks, but for all but one of the remaining tricks, hence going one down. They'd rejected my 'claim' out of pure generosity.
Now, I'm perplexed by this. I would have thought it difficult to mishandle the CLAIM button, and it always suggests "Claim all remaining tricks" as the default. And I use a desktop PC with a mouse, and don't recall ever having mis-clicked on BBO.
So is there a possible bug in the CLAIM button?
Another possibility is that I had some sort of 'senior moment'. I am well aware that these things do sometimes happen, with me

A third possibility is that this was all a deliberate wind-up by my opponents, with the intention of either (a) covering for their incompetence in rejecting a clear-cut claim, or (b) breaking up my concentration. Or both

Is there a way of retrieving all that happened during the hand in question, including the chat plus any CLAIM attempts? Playing out the hand in 'movie' view doesn't reveal anything.
Anyway, I would not have suggested the 'bug' theory but for one other thing. In another, totally unrelated hand, I played out a not-too-difficult 3NT and was surprised to get an unusually good IMPs score. So I looked at how other tables had fared, using the Traveller facility, and came across this. It would appear that, in 5♣xx, the unfortunate declarer intended at trick 6 to claim all the remaining tricks, but somehow contrived to concede the remaining tricks (including the top trumps!!) instead. His opponents, it seems, were not so magnanimous, and the result was a whopping -23 IMPs!
So maybe there is a problem with CLAIM. Should I be wary?
