'Dead' decks of cards?
I am not a cardplayer and only know very little about the culture of poker and gambling. I was therefore unable to understand one scene in "the big game", where they are just getting ready to play:
Lancey and "The Kid" are allowed to inspect the card decks. They do this by feeling the packs, and sniffing (!) them. Once they've gone through all the decks, The Kid has sorted out a few packs which he calls "dead", and then hands these back to the man who brought them. I assume that these dead decks are then discarded.
Now, what is the purpose of this ritual? Is it just gambling superstition, or does it serve a more rational purpose?
And another question: when Shooter has shuffled the first deck, he lays it flat on the table. The players then, one by one, proceed to tap the table once with their fist. Again, what is the purpose and significance of this ritual?
Thanks in advance for any light that can be shed on this!
