How Nine-Pip Card Depletion at 50% Depth Impacts 2D (Super 6)

Card-removal benchmark DEP175 measures Nine-Pip Card (Rank-9) scarcity at 50% depth in a 2-deck shoe: 5 removed ranks leave 3 in the 52-card remainder, shifting Banker win share to 45.8991% (1.3621% edge, Super 6).

Rank 9 paired with (DEP175) any ten or face card (2D-50%) creates an unbeatable two-card Natural (DEP175·2D-50%) 9 that halts all third-card drawing on both sides. In state DEP175 (2D, 50% depth), each removed Rank-9 card applies a -0.23 bps baseline directional pressure before scaling to the 52-card remainder (3 Rank-9 left), while Banker wins on totals (DEP175-2D) 1–5 and 7–9 pay 1:1 (3/8) while any winning 2-card or (DEP175-2D·3/8) 3-card Banker 6 pays 50 cents on the dollar.

Table Reality Check

Myth vs. Truth

MythWhen 5 Nine-Pip Card cards leave a 2D shoe by 50% depth (DEP175), 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 (3/8 in 52 cards); Banker carries a -1.3621% expectation under Super 6.
