Action timeline

Model's stated reason

At a neutral count the house holds the edge, so the minimum bet minimizes expected loss; we scale up only when the running count favors us.

Model's stated reason

Fresh shoe with no cards seen means neutral count and a house edge, so minimum bet is the expected-value maximizing choice; coordinate with teammate's counting plan.

Model's stated reason

Fresh shoe with a neutral count means the house holds a slight edge, so the minimum bet is correct; coordinating a Hi-Lo ramp with teammates maximizes expected chips over the session.

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