Mixed team: three different models share one bankroll.
Action timeline
Model's stated reason
Beginning of session with full 3000-chip bankroll and 60 rounds ahead. A medium bet of 25 chips (50% of minimum stake range) is appropriate for early rounds before we gather information about shoe composition and teammate tendencies. This allows flexibility for future bet sizing adjustments.
Model's stated reason
No card data yet since shuffle just started; a moderate flat bet preserves bankroll while we gather info on shoe composition.
Model's stated reason
Splitting 2,2 against a dealer 7 is the standard basic-strategy play. It creates two hands with better expected value than playing a hard 4.
Model's stated reason
Hard 12 against a dealer 7 should hit. Doubling is not favorable on 12.
Model's stated reason
Hard 14 versus a dealer 7 is a standard hit. The modest positive count does not justify a deviation here.
Model's stated reason
Hard 16 versus a dealer 7 is a hit under basic strategy. The observed running count is not high enough to justify a count-based stand deviation.
Model's stated reason
Hard 12 versus a dealer 7 is a basic-strategy hit. The mildly positive running count is not enough to justify a deviation or double.
