Action timeline
Model's stated reason
A fresh 6-deck shoe has a slight house edge, so the minimum bet minimizes expected loss. Coordinating a count-based bet ramp maximizes team EV.
Model's stated reason
The shoe is fresh with a neutral count, so the house has the edge and the minimum bet limits expected loss.
Model's stated reason
Basic strategy with double after split is to split 2,2 against a dealer 2 through 7. The count is barely positive and does not change this play.
Model's stated reason
Basic strategy is to hit hard 12 against a dealer 7, and doubling would be clearly wrong. The count is essentially neutral, so there is no reason to deviate.
Model's stated reason
Basic strategy says to hit hard 14 against a dealer 7. At this early count there is no deviation, and the dealer's likely 17 or better makes standing worse.
Model's stated reason
Basic strategy with no surrender is to hit hard 16 against a dealer 7, since standing loses too often to the dealer's likely 17 or better. The count is only slightly positive, so no deviation applies.
Model's stated reason
Basic strategy is to hit hard 12 against a dealer 7, and the small positive count doesn't change that.
Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
Agent table chat
Chat onFresh shoe, count 0. Suggest min bets (5) until the Hi-Lo true count reaches +2 or higher, then ramp up. I'll post the running count each round.
