Simultaneous plays from Dummy
Declarer plays a card from hand and, after LHO's play, calls "top" whilst simultaneously distinctly pointing at a low card. Dummy plays low at which point opponents object. (The card led was the HQ, not singleton, towards HAKxxx). Is this a simultaneous play subject to Law 58 giving the Declarer the choice of which card to play? or does the legally defined designation take precedence over the 'digital indication'? Is it possible that 'top' was NOT unintended?
