Self team: one model plays all three seats against the dealer.

654 / 654

Action timeline

Model's stated reason

True count is zero on a new shoe, so the house edge favors the smallest legal bet until a positive count appears.

Model's stated reason

Fresh six-deck shoe with no cards seen, so there is no count edge. Minimum bet preserves the shared bankroll until the count turns positive.

Model's stated reason

Pair of 2s versus dealer 7 is a basic-strategy split with double-after-split allowed; splitting gives two low hands a chance to improve rather than playing a hard 4.

Model's stated reason

Hard 12 versus a dealer 7 is a basic-strategy hit; the running count is only about +1, far too small to justify standing or doubling.

Model's stated reason

Hard 14 against a dealer 7 is a basic-strategy hit, and the modest positive count does not justify standing.

Model's stated reason

Hard 16 versus a dealer 7 is a clear hit under basic strategy, and a modest positive count does not justify standing.

Model's stated reason

Hard 12 against a dealer 7 is a hit under basic strategy; doubling is too risky because any 10 busts and the hand is not strong enough to commit extra chips.

Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
