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.

How Two-Pip (Deuce) Depletion at 75% Depth Impacts 2D (4% Vig)

When a 2D shoe reaches 75% cut-card depth (26 of 104 cards undealt, state DEP115) with 7 Two-Pip (Deuce) cards removed and 1 remaining, Player wins 44.5651% (1.3370% edge) while Banker wins 45.9022% (0.4991% edge under 4%).

Comparing initial 104-card 2D weights against stub DEP115 (26 cards, 75% depth, 1 Rank-2 left) illustrates how on banker total 4, (dep115) banker draws against player third-card (2d-75%) 2 through 7; removing 2s (dep115·2d-75%) trims low-pip player third-card triggers (+0.52 bps slope, 0.4991% 4% Vig edge).

Table Reality Check

Myth vs. Truth

MythWhen 7 Two-Pip (Deuce) cards leave a 2D shoe by 75% depth (DEP115), 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 (1/8 in 26 cards); Banker carries a -0.4991% expectation under 4%.
