Action timeline
Model's stated reason
With no count information and a negative expected value per bet, the minimum bet maximizes the team's expected chips by minimizing total exposure.
Model's stated reason
The seen cards give a modest negative Hi-Lo count, so there is no positive edge; minimum bet preserves the shared bankroll.
Model's stated reason
The running Hi-Lo count is slightly negative (-2) with no player edge, so the optimal team play is to minimize exposure and preserve the shared bankroll.
Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
