Then, declarer calls for a "high spade". As declarer, I believe there's an uncontroversial right to say "er I meant club" if there's no pause, but what if declarer doesn't realize the use of the wrong word until dummy is reaching for it?
As dummy:
- must one play the "high" spade with no comment, despite being a singleton 4?
- may one ask "there's only one, please confirm you mean the spade 4?"
- something else? (...kick partner? kick opponent for cover and play the club ace?)
The obvious and expected (by everyone at the table) line of play was to run the top clubs, ruff a club in declarer's hand, and ruff a heart back in the dummy. This was also the plan of the declarer, but declarer looked at the top black card and just used the wrong word for it.
On the one hand, law 46.B.1 is fairly unequivocal with "If declarer, in playing from dummy, calls ``high'', or words of like import, he is deemed to have called the highest card". On the other hand, 45.4.b provides some slack if a correction to a call is made "without pause for thought", but I don't really know how to interpret that here if declarer doesn't realize the mis-call until it's seen. On the gripping hand, declarer is already kind of in the wrong here against 46.A's "declarer should clearly state both the suit and the rank of the desired card", but is there anyone in the world who actually does do this aside from pedantic me?
For what it's worth, I believe in the game in question declarer could have asked to correct and opponents would have been OK with it, but declarer took the conservative path (and a bottom).
Thanks for any opinions and enlightenment!
