Action timeline

Model's stated reason

With no cards exposed, the shoe offers no counting advantage, so the minimum wager limits expected losses.

Model's stated reason

Fresh shoe with a neutral running count calls for the minimum bet of 5.

Model's stated reason

Pair of 2s against a dealer 7 is a standard split, improving expected value over hitting a hard 4.

Model's stated reason

Hard 12 against a dealer 7 is a basic-strategy hit; standing risks losing to a made 17-21, and doubling is not justified with 12.

Model's stated reason

Hard 14 against a dealer 7 is a basic-strategy hit; standing loses to most dealer made hands, while hitting gives a chance to improve.

Model's stated reason

Hard 16 against a dealer 7 is a basic-strategy hit; the positive Hi-Lo count does not justify standing.

Model's stated reason

Hard 12 against a dealer 7 is a basic-strategy hit; standing is too weak and doubling a 12 is not justified.

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