2-Deck Two-Pip (Deuce) Depletion at 10% Penetration (5% Audit DEP109)

Removing 1 of 8 Two-Pip (Deuce) (Rank-2) cards at 10% penetration of a 2-deck (104-card) shoe leaves 7 Rank-2 cards inside a 94-card stub (DEP109), producing 45.9000% Banker wins, 44.5674% Player wins, 9.5326% Ties, and a 0.9623% 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

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 Two-Pip (Deuce) Depletion at 10% Depth Impacts 2D (5% Vig)

Removing 1 of 8 Rank-2 cards by the 10% mark of a 2-deck shoe (DEP109, 94 cards left) leaves 7 Two-Pip (Deuce) cards and adjusts conditional probabilities to 45.9000% Banker, 44.5674% Player, and 9.5326% Tie under 5%.

In 2D audit DEP109 (94/104 stub at 10% depth), depleting 2s shifts the (dep109-rank-2) probability of banker converting a (94c) two-card 4 or 5 into (dep109-rank-2·94c) a winning three-card 6 or 7. Removing 1 Rank-2 cards (+0.52 bps per card) alongside 5% Vig rules sets Tie hold to 14.2065% (9.5326% frequency).

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP109 · 2D)

Even at 10% penetration in DEP109 where 1 Rank-2 cards have exited a 2D shoe (7 left in 94 cards), derived-road red and blue entries measure structural regularity on the Big Road—not whether Banker (-0.9623% EV, 5% Vig) or Player (-1.3327% EV) is favored next.

  • DEP109 (2D 10%): 94/104 cards with 7/8 Rank-2 (4A).
  • DEP109 (Rank-2 split): 45.9000% Banker, 44.5674% Player, 9.5326% Tie in 94 2D cards (4B).
  • DEP109 (5% Vig EV): -0.9623% Banker, -1.3327% Player, -14.2065% Tie, 0.9311 SD at 10% (4C).
  • DEP109 (2D roads): red/blue marks log Big Road columns, never 7 Rank-2 stub count (4D).
Table Reality Check

Myth vs. Truth

MythWhen 1 Two-Pip (Deuce) cards leave a 2D shoe by 10% depth (DEP109), 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-2 stub counts (7/8 in 94 cards); Banker carries a -0.9623% expectation under 5%.
