I believe there is also a direction where subsequent "plays" are taken into account when deciding defective claims (i.e assessment of how likely hearts would be played can be affected by actual "play" after a claim). I'm not sure about this though.
Actually it is a Law, L70D3, precisely the one Gordon quoted. It reads:
"In accordance with Law 68D play should have ceased, but if any play has occurred after the claim this may provide evidence to be deemed part of the clarification of the claim. The Director may accept it as evidence of the players probable plays subsequent to the claim and/or of the accuracy of the claim."
There was a case a while back where a player put his cards down and claimed "on a double squeeze". The op said "play it out", he did, and he messed it up. A ruling was sought, and the ruling was that the contract was made, since the claim was valid and the play after it was void and irrelevant. But that was under the old laws, which didn't have 70D3, and I believe that would not be the appropriate ruling if the same thing happened today.
Ed refers to Laws 10 and 11. But I do not believe that adjudicating on a claim is the rectification of an irregularity. We should therefore read L70D3 and do what we can with that, not look at 10 and 11.
I therefore think that once LHO has foolishly displayed his trump and dummy has over-ruffed it, we need to consider the claim from that position. Declarer does have the rest from that point, provided he uses his trump in hand for ruffing. Is playing a round of trumps rather than ruffing worse than careless? I think it is arguable either way. On balance I think I'd rule one down.
