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.

How Eight-Pip Card Depletion at 70% Depth Impacts 2D (5% Vig)

Quantitative proof DEP168 documents 2D rank depletion at 70% depth: 6 exited Rank-8 cards leave 2 of 8 in the 31-card stub, generating 45.8979% Banker wins (-0.9666% EV under 5% Vig) and 44.5696% Player wins.

Why does Rank-8 carry a -0.50 bps per-card effect in DEP168? On Banker total 3, (DEP168) Banker draws against every Player (2D-70%) third card except 8; removing (DEP168·2D-70%) 8s eliminates Banker 3's sole standing exception, and at 70% penetration (2 Eight-Pip Card cards left in 31 2D cards), with 70% of cards (dep168-2d) dealt and 30% remaining ahead (2/8) of the cut card, winning (dep168-2d·2/8) banker bets pay 0.95 to 1.

Table Reality Check

Myth vs. Truth

MythWhen 6 Eight-Pip Card cards leave a 2D shoe by 70% depth (DEP168), 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-8 stub counts (2/8 in 31 cards); Banker carries a -0.9666% expectation under 5%.
