1-Deck Nine-Pip Card Depletion at 75% Penetration (4% Audit DEP088)

Removing 3 of 4 Nine-Pip Card (Rank-9) cards at 75% penetration of a 1-deck (52-card) shoe leaves 1 Rank-9 cards inside a 13-card stub (DEP088), producing 45.9586% Banker wins, 44.5258% Player wins, 9.5156% Ties, and a 0.4056% Banker house edge under 4%.

Step-by-Step Mark Proofs (Rule 1 & Rule 2)
Big Eye Boy Mark #2

Column 2 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

  1. Column 3 starts, so use Rule 1: compare Column 2 with Column 1, 1 column further back.
  2. Column 2 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

Common table reading watchout: Comparing the wrong columns. Compare Column 2, the one that just finished, with Column 1.

Small Road Mark #2

Column 3 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

  1. Column 4 starts, so use Rule 1: compare Column 3 with Column 1, 2 columns further back.

Cockroach Pig Mark #2

Column 5 has 1 bead. Column 2 has 2 beads. Different depth → blue (≠).

  1. Column 6 starts, so use Rule 1: compare Column 5 with Column 2, 3 columns further back.
  2. Column 5 has 1 bead. Column 2 has 2 beads. Different depth → blue (≠).

How Nine-Pip Card Depletion at 75% Depth Impacts 1D (4% Vig)

Finite-shoe specification DEP088 tracks Rank-9 removal at 75% depth in 1-deck play: with 1 of 4 Nine-Pip Card cards left in the 13-card stub, Tie incidence is 9.5156% and Banker expectation settles at -0.4056% (4% Vig).

Mechanical draw trees in DEP088 reflect how when 9s are depleted (dep088-rank-9) late in the shoe, more (13c) hands bypass four-card natural resolution (dep088-rank-9·13c) and enter the five- and six-card tableau. At 75% 1D depth (1 Rank-9 left of 4 in 13 cards, -0.23 bps slope), three-quarters of the shoe (dep088-1d) has been dealt and winning (1/4) banker wagers return 0.96 units (dep088-1d·1/4) net per unit risked.

  • DEP088 (4% Vig EV): -0.4056% Banker, -1.4328% Player, -14.3600% Tie, 0.9397 SD at 75% (4C).
  • DEP088 (1D roads): red/blue marks log Big Road columns, never 1 Rank-9 stub count (4D).
Table Reality Check

Myth vs. Truth

MythWhen 3 Nine-Pip Card cards leave a 1D shoe by 75% depth (DEP088), Big Eye Boy red or blue marks show whether Banker or Player will win next.
TruthDerived-road red and blue marks only compare Big Road column lengths and never track Rank-9 stub counts (1/4 in 13 cards); Banker carries a -0.4056% expectation under 4%.
