Please enjoy this guest video by “nubs 1981”. In this video, nubs shows one of the most common ergonomic reasons for hole-card exposure in a blackjack shoe game, namely, the shoe is placed too close to the edge/lip of the discard tray. In order to avoid the tray, the dealer lifts the corner of the card over the edge, exposing the card to a spotter at third base.
I have a similar video taken from actual surveillance footage that I used to share in my seminars, but I am unable to share that video in a public forum. What I am saying is that this happens in real life.
Thank you nubs 1981.
