Decks remaining from the discard tray

The Running Count alone misleads you. A Running Count of +6 means six extra high cards are somewhere in the undealt shoe. With five decks left, those six cards are spread across 260, barely more than one extra high card per deck. With one deck left, all six sit in 52 cards and the shoe is loaded. Same Running Count, very different edge. You need the decks remaining to tell the two apart.

No one hands you that number. You read it from the discard tray, the clear plastic stack of dealt cards beside the dealer. A full deck is about two centimeters of stacked cards, roughly a thumb's width. Half a deck is about a finger. Glance at the tray, estimate the cards dealt in half-deck steps, and subtract from the game's total. In a six-deck game, a tray that looks like two and a half decks means three and a half remain.

Half-deck precision is the professional standard. Finer adds nothing, because your Running Count carries more noise than that. Coarser costs money. If you call 2 decks remaining 3, a true +3 becomes a computed +2, and you under-bet a hot shoe all night.

Some casinos use taller trays or angle them away from players, so practice estimating from an angle as well as straight on. In double-deck games dealt face-down, estimate from the cards in play plus the discards. The Checkpoint shows you a tray and a shoe from a six-deck game. Estimate the decks remaining to the nearest half.
