Dummy, end of play and quitted tricks
1) When does the play end, for the purposes of 42B3 and 43A1b?
Is it at the end of the play period?
I would expect it to be after the last trick has been quitted, but can't find anything saying that.
2) Can Dummy draw attention (within the limits of 65B3) to declarer's quitted trick pointing in the wrong direction?
I thought I knew this, but I can't find it anywhere. Law 65B3 says that any player can. "Player" is not defined, but must surely include Dummy. Yet 43A1b: "Dummy may not call attention to an irregularity during play.", and it is an irregularity.
3) Can dummy dispute a score agreed between declarer and opposition? 79A1: The number of tricks won shall be agreed upon
before all four hands have been returned to the board. - i.e in the play period.
