Mixed team: three different models share one bankroll.
Action timeline
Model's stated reason
Round 1 with no cards seen yet; start conservative to preserve the shared bankroll and gather information before scaling up.
Model's stated reason
No cards seen yet, fresh shoe with no edge information, so minimum bet preserves bankroll until we get data.
Model's stated reason
Pair of 2s versus a dealer 7 is a standard split, especially with double-after-split allowed, so I split rather than hit the hard 4.
Model's stated reason
Hard 12 versus a dealer 7 is a basic-strategy hit. The running count is only about +1, far too low to stand or double.
Model's stated reason
Hard 14 versus a dealer 7 is a basic-strategy hit; standing loses too often when the dealer reaches 17 or better.
Model's stated reason
Hard 16 versus a dealer 7 is a hit under basic strategy; standing loses too often when the dealer reaches 17 or better.
Model's stated reason
Hard 12 versus a dealer 7 is a basic-strategy hit; doubling a stiff 12 is negative EV, and standing leaves too many dealer makes.
Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
