Wasn't it only pran, out on a limb, who argued for the second one?
My recollection is that Bluejak has said that a defective trick may be defined by what cards are found in the played cards of that trick, and is not always defined by what cards anyone remembers being played to it at the time, even if there is unanimity on that.
Suppose a card is played, is misplaced and then is played again. Certainly in that situation I believe Bluejak has argued that the first trick it was apparently played to is defective, even if everyone agrees that the card was played to that trick. If that is so, then the criterion that everyone recalls 4 cards being properly played to a trick, and which ones, does not suffice to avoid it being defective.
I don't like this argument, but I give it time of day because it has been argued by rather more than one person out on a limb.
