682 / 682

Action timeline

Model's stated reason

No cards seen, so house edge applies; bet the minimum to conserve bankroll until the count becomes favorable.

Model's stated reason

First round of a fresh shoe with no cards seen yet, so the count is neutral. Following the teammate's Hi-Lo plan, I'll start with the minimum bet and wait for the running count to climb before increasing.

Model's stated reason

Running count is +2 with nearly a full six-deck shoe remaining, giving a true count well under +1, so the house still has the edge and the minimum bet is correct.

Model's stated reason

Fresh shoe, running count is +2 with ~5.8 decks remaining (true count ~+0.3), still below the +2 threshold for raising. Sticking with the min 5-chip bet to preserve bankroll until the count justifies a larger wager.

Model's stated reason

The true count is only about +0.3, so there is no meaningful advantage to justify increasing the bet.

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