There isn't a canonical list of correct procedures, but claiming in such a way as to avoid partner making a mistake must at the very least violate correct procedure. If you want to argue that declarer gets a trick under law 57 or similar adjustment under law 23, that's not unreasonable. However, overtaking the HK seems like such a poor play that I would have to be convinced that West doesn't know the HQ is still out there.
You have both a right and a wrong idea here. Correct procedure in claiming is defined by Law 68, and the claimer in this case has not breached that law. However, in adjudicating the claim, Law 70D2 applies:
Quote
The Director shall not accept any part of a defender’s claim that depends on his partner’s selecting a particular play from among alternative normal plays.
So the adjudication of this claim boils down to the question whether West overtaking East's king is normal within the meaning of the laws. It would certainly be inferior to do so, it's probably careless to do so, even without the information that partner has the
♣A, but is it irrational? If it's irrational to overtake, then it is not normal, and the TD should not rule that West might do so. If OTOH it's not irrational, but merely careless or inferior, or possibly both, then the TD
should rule that West might overtake.
UdcaDenny writes "Declarer S played low H from dummy and when he followed with the 10 E claimed his Ace of C before W played a card. S called TD who by the way was his dummy partner at the table. TD said W could have played wrong overtaking K and give S the last trick with Q. With KQ E would off courxe normally play the Q so there is no reason why W shud overtake. Can this be a fair judgement from a playing TD who also benefite from his decision?"
