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 3 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

How Nine-Pip Card Depletion at 70% Depth Impacts 1D (5% Vig)

When a 1D shoe reaches 70% cut-card depth (16 of 52 cards undealt, state DEP087) with 3 Nine-Pip Card cards removed and 1 remaining, Player wins 44.5258% (1.4328% edge) while Banker wins 45.9586% (0.8651% edge under 5%).

For DEP087 (1-deck shoe, 70% dealt), rank 9 paired with (dep087) any ten or face card (1d-70%) creates an unbeatable two-card natural (dep087·1d-70%) 9 that halts all third-card drawing on both sides. Holding 1 of 4 Rank-9 cards in a 16-card stub with -0.23 bps rank slope yields 45.9586% Banker, 44.5258% Player, and 9.5156% Tie.

Third-Card Tableau Sensitivity vs Derived-Road Marks (DEP087 · 1D)

Statistical verification of DEP087 (1D, 70% penetration, 1 Nine-Pip Card cards in 16 stub cards) demonstrates why single-rank depletion (3 Rank-9 dealt) shifts edges by basis points around -0.8651% (5% Vig).

  • DEP087 (1D 70%): 16/52 cards with 1/4 Rank-9 (6A).
  • DEP087 (Rank-9 split): 45.9586% Banker, 44.5258% Player, 9.5156% Tie in 16 1D cards (6B).
  • DEP087 (5% Vig EV): -0.8651% Banker, -1.4328% Player, -14.3599% Tie, 0.9392 SD at 70% (6C).
  • DEP087 (1D roads): red/blue marks log Big Road columns, never 1 Rank-9 stub count (6D).
Table Reality Check

Myth vs. Truth

MythWhen 3 Nine-Pip Card cards leave a 1D shoe by 70% depth (DEP087), 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 (1/4 in 16 cards); Banker carries a -0.8651% expectation under 5%.
