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 Nine-Pip Card Depletion at 40% Depth Impacts 1D (4% Vig)

Quantitative proof DEP084 documents 1D rank depletion at 40% depth: 2 exited Rank-9 cards leave 2 of 4 in the 31-card stub, generating 45.9590% Banker wins (-0.4048% EV under 4% Vig) and 44.5254% Player wins.

Rank 9 paired with (DEP084) any ten or face card (1D-40%) creates an unbeatable two-card Natural (DEP084·1D-40%) 9 that halts all third-card drawing on both sides. In state DEP084 (1D, 40% depth), each removed Rank-9 card applies a -0.23 bps baseline directional pressure before scaling to the 31-card remainder (2 Rank-9 left), while Winning Banker wagers collect (DEP084-1D) 0.96 units per unit staked (2/4) with 60% of the shoe (DEP084-1D·2/4) still inside the acrylic carrier.

Table Reality Check

Myth vs. Truth

MythWhen 2 Nine-Pip Card cards leave a 1D shoe by 40% depth (DEP084), 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 (2/4 in 31 cards); Banker carries a -0.4048% expectation under 4%.
