2-Deck Nine-Pip Card Depletion at 40% Penetration (4% Audit DEP174)

Removing 4 of 8 Nine-Pip Card (Rank-9) cards at 40% penetration of a 2-deck (104-card) shoe leaves 4 Rank-9 cards inside a 62-card stub (DEP174), producing 45.8993% Banker wins, 44.5681% Player wins, 9.5326% Ties, and a 0.5048% 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 4 has 1 bead. Column 2 has 2 beads. Different depth → blue (≠).

  1. Column 5 starts, so use Rule 1: compare Column 4 with Column 2, 2 columns further back.
  2. Column 4 has 1 bead. Column 2 has 2 beads. Different depth → blue (≠).

Common table reading watchout: Comparing the wrong columns. Compare Column 4, the one that just finished, with Column 2.

Cockroach Pig Mark #2

This bead is at Row 2. Column 2 has a bead at Row 2 too → red (=).

  1. Column 5 goes down to Row 2, so use Rule 2: look 3 columns back, at Column 2.
  2. Column 2 has a bead at Row 2 too → red (=).

Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 2 stopped exactly one row above this bead.

How Nine-Pip Card Depletion at 40% Depth Impacts 2D (4% Vig)

Under 4% settlement (4% Vig), combinatorial state DEP174 models a 2D carrier with 62 cards left (40% dealt) and 4/8 Nine-Pip Card cards remaining, producing a 0.5048% Banker edge versus 1.3312% on Player.

In six-card resolution tree DEP174 (2D at 40% depth, 62 cards left), when 9s are depleted (dep174-rank-9) late in the shoe, more (62c) hands bypass four-card natural resolution (dep174-rank-9·62c) and enter the five- and six-card tableau; removing 4 of 8 Rank-9 cards (-0.23 bps weight) leaves Banker at -0.5048% EV under 4%.

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP174 · 2D)

Whether DEP174 is observed in double-deck European salon privé carriers and two-deck shoe pits at 40% depth (62/104 cards left, 4 Rank-9 remaining), 4% Vig settlement locks Banker EV at -0.5048% and Player EV at -1.3312% with 9.5326% Ties.

  • DEP174 (2D 40%): 62/104 cards with 4/8 Rank-9 (7A).
  • DEP174 (Rank-9 split): 45.8993% Banker, 44.5681% Player, 9.5326% Tie in 62 2D cards (7B).
  • DEP174 (4% Vig EV): -0.5048% Banker, -1.3312% Player, -14.2068% Tie, 0.9362 SD at 40% (7C).
  • DEP174 (2D roads): red/blue marks log Big Road columns, never 4 Rank-9 stub count (7D).
Table Reality Check

Myth vs. Truth

MythWhen 4 Nine-Pip Card cards leave a 2D shoe by 40% depth (DEP174), 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 (4/8 in 62 cards); Banker carries a -0.5048% expectation under 4%.
