Action timeline

Model's stated reason

With no cards seen and no information indicating a player advantage, use the minimum bet to limit expected losses.

Model's stated reason

The exposed cards produce a Hi-Lo running count of about -2, with very little of the six-deck shoe dealt, so there is no favorable count justification to raise the bet.

Model's stated reason

The exposed cards make the count slightly unfavorable, so the minimum bet limits our exposure while preserving bankroll.

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