2-Deck Nine-Pip Card Depletion at 10% Penetration (5% Audit DEP172)

Removing 1 of 8 Nine-Pip Card (Rank-9) cards at 10% penetration of a 2-deck (104-card) shoe leaves 7 Rank-9 cards inside a 94-card stub (DEP172), producing 45.8997% Banker wins, 44.5677% Player wins, 9.5326% Ties, and a 0.9630% Banker house edge under 5%.

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

This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠).

  1. Column 3 goes down to Row 3, so use Rule 2: look 2 columns back, at Column 1.
  2. Column 1 stopped at Row 2, one row above → blue (≠).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.

Cockroach Pig Mark #2

This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠).

  1. Column 4 goes down to Row 3, so use Rule 2: look 3 columns back, at Column 1.
  2. Column 1 stopped at Row 2, one row above → blue (≠).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.

How Nine-Pip Card Depletion at 10% Depth Impacts 2D (5% Vig)

Finite-shoe specification DEP172 tracks Rank-9 removal at 10% depth in 2-deck play: with 7 of 8 Nine-Pip Card cards left in the 94-card stub, Tie incidence is 9.5326% and Banker expectation settles at -0.9630% (5% Vig).

Because when 9s are depleted (dep172-rank-9) late in the shoe, more (94c) hands bypass four-card natural resolution (dep172-rank-9·94c) and enter the five- and six-card tableau, state DEP172 (10% 2D depth, 1 Rank-9 removed, 7 in 94 cards) registers a -0.23 bps rank derivative and 0.9630% Banker house edge (5% Vig).

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP172 · 2D)

Cut-card protocol at 10% depth in DEP172 (2D, 94 stub cards containing 7 Rank-9 cards) ensures the shoe reshuffles long before 5% house hold (0.9630% Banker / 1.3320% Player) is overturned.

  • DEP172 (2D 10%): 94/104 cards with 7/8 Rank-9 (4A).
  • DEP172 (Rank-9 split): 45.8997% Banker, 44.5677% Player, 9.5326% Tie in 94 2D cards (4B).
  • DEP172 (5% Vig EV): -0.9630% Banker, -1.3320% Player, -14.2066% Tie, 0.9332 SD at 10% (4C).
  • DEP172 (2D roads): red/blue marks log Big Road columns, never 7 Rank-9 stub count (4D).
Table Reality Check

Myth vs. Truth

MythWhen 1 Nine-Pip Card cards leave a 2D shoe by 10% depth (DEP172), 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 (7/8 in 94 cards); Banker carries a -0.9630% expectation under 5%.
