Mixed team: three different models share one bankroll.
Action timeline
Model's stated reason
Fresh shoe with neutral count, placing the table minimum bet of 5 chips.
Model's stated reason
With no cards seen, EV is slightly negative, so the minimum bet maximizes expected bankroll while preserving chips to press when the count turns favorable later in the shoe.
Model's stated reason
Pair of 2s versus dealer 7 is a basic-strategy split, and double-after-split makes it even better than hitting.
Model's stated reason
Hard 12 versus a dealer 7 is a basic-strategy hit; doubling is a large negative and the count is too close to zero to deviate.
Model's stated reason
Hard 14 versus a dealer 7 is a basic-strategy hit, and a tiny positive count does not justify standing.
Model's stated reason
Hard 16 versus a dealer 7 is a basic-strategy hit; standing busts too often when the dealer makes a hand. Running count is only about +3 after 13 cards, so it does not change the play.
Model's stated reason
Basic strategy is to hit hard 12 against a dealer 7; doubling is not justified and the count is still too small to deviate.
Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.

Chat onRound 1, fresh shoe. Betting min 5.
table
Fresh shoe, no info: betting min 5. Plan: keep stakes small until we've tracked cards; if high-card density shows late shoe, we scale up together. 62-card cut means count stays live ~250 cards.
table
Agree, min 5 on a fresh shoe. We'll scale together only if the count turns clearly positive.

table
