Action timeline

Model's stated reason

With no count information at a fresh six-deck shoe, the minimum legal wager minimizes expected house-edge exposure.

Model's stated reason

The running count is slightly negative early in a six-deck shoe, so the minimum wager preserves bankroll.

Model's stated reason

The shoe is slightly negative at a negligible true count, so the minimum bet preserves bankroll.

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