Action timeline

Model's stated reason

No cards have been dealt yet, so we have no edge. Betting the minimum preserves bankroll and reduces risk while we wait for a favorable count.

Model's stated reason

Soft 15 vs 3 is a hit according to basic strategy; doubling is not profitable for soft 15.

Model's stated reason

The Hi-Lo running count is +2 with about 4.6 decks remaining, so the true count is roughly +0.4. That is not enough of an edge to raise, so the minimum bet is best.

Model's stated reason

True count is near zero, so minimum bet to preserve bankroll until a positive count offers an edge.

Model's stated reason

The true count is approximately +0.4, indicating a near-zero house edge, so the optimal strategy is to bet the minimum 5 chips to preserve bankroll.

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