Mixed team: three different models share one bankroll.
Action timeline
Model's stated reason
With no information suggesting a player advantage in a fresh shoe, the minimum legal wager minimizes expected house edge.
Model's stated reason
A fresh 6-deck shoe with these rules has a small house edge, so the minimum bet minimizes expected loss. Coordinating on a Hi-Lo count lets us raise bets later when the shoe favors us.
Model's stated reason
Pair of 2s vs dealer 7 is a basic-strategy split; it turns a weak 4 into two playable hands. With a 3000 bankroll, the extra min bet is low risk.
Model's stated reason
Hard 12 vs dealer 7 is a basic-strategy hit; the count is neutral so there is no reason to deviate.
Model's stated reason
Hard 14 vs dealer 7 is a basic-strategy hit because the dealer's upcard is strong and standing risks losing to a likely 17 or better.
Model's stated reason
Hard 20 is a made hand; hitting risks busting and standing maximizes expected value against dealer 7.
Model's stated reason
The running count is positive but the true count remains below the planned +2 betting threshold. Minimum exposure is appropriate.
Model's stated reason
The true count is about +1.2, which gives roughly a break-even edge and is below the team's +2 ramp threshold. I'm keeping to the minimum bet.

Agreed, fresh shoe, neutral count. Min bet from me too. Let's track the running count (Hi-Lo) and ramp up only when the true count is +2 or higher.

Hi-Lo RC is +5 after 30 exposed cards; with roughly 5.4 decks left, TC is about +1. Minimum bet.
table
My recount of all 30 cards gives Hi-Lo RC +7, not +5. With about 5.4 decks left, TC is about +1.3. That's still below our +2 threshold, so I'm betting the minimum.
table

table
My recount of all 40 cards gives RC +10, TC about +1.9 with 5.23 decks left. That's right at the threshold, so I'm matching the modest 15-chip ramp. Go to the max only if the TC climbs to +3 or higher.

table
Confirmed: my recount of all 50 cards is RC +8, about 5.04 decks left, so TC is roughly +1.6. That's a marginal edge, so I'm going just slightly above minimum at 10. We ramp harder at TC +2 or higher.

table
Full Hi-Lo recount through 70 exposed cards: RC +10, about 4.65 decks remain, TC roughly +2.15. Modest 15-chip ramp is warranted.
table
Confirmed: my recount of all 70 cards gives RC +10. About 4.65 decks remain, so TC is roughly +2.15. That's just over the threshold, so I'm making a modest ramp to 20. We go bigger if the TC reaches +3.
table

table
Soft 18 vs dealer 10 is a hit. Initial deal reduces the prior RC to roughly +8 (TC near +2), not enough for a deviation.
table
Standing hard 16 vs T: with the positive true count, the 16-vs-10 index calls for a stand rather than the low-count basic-strategy hit.
table
Hitting soft 14 vs 10 per basic strategy; no double at this count.
table

table
My full recount of all 114 cards gives RC +12. With about 3.8 decks left, TC is roughly +3.1. That's a solid edge, so I'm betting the max of 50. Let's all stay at max while TC is +2 or higher.
table
Agreed, RC +10/+12, TC ~+2.6 to +3.1. Staying at max bet while the edge holds.
table

Drew Jc for hard 14 vs J. Hitting per basic strategy; no stand index applies at this count. The extra J puts RC around +4 to +6, so TC is about +1.5.

table
Full recount of 135 exposed cards gives Hi-Lo RC +3; about 3.4 decks remain, so TC is under +1. Minimum bet.
