doesnt matter, make sure to get to the spades fast in the beginning and ask them do u want to stop here? if they say no u keep going if they tellyou to stop on a random card u simply say i dont want to stop here now and you try to memmorize where the 10 cards are so the 2 next cards is going to be this one so u say stop here? they will see different card not the same with the last one u asked for so they will be legit
i really dont know the exact reason as to how this trick works, but it just does as long as they dont chose one of your 10 cards or if the top card you flip over is already one of your cards when you go to cut the deck where they can see the actual cards
