Self team: one model plays all three seats against the dealer.
Action timeline
Model's stated reason
With a fresh shoe there is no count edge, so a low bet limits variance against the house edge; I will scale up later if the cards seen favor the player.
Model's stated reason
With no cards seen the count is neutral and the house has a small edge, so a low bet limits expected loss. Matching seat_1's plan keeps the team coordinated until the count gives an advantage.
Model's stated reason
Basic strategy for 2,2 vs a dealer 7 is to split, and double after split is allowed, which makes splitting slightly better.
Model's stated reason
Hard 14 against a dealer 7 is a stand in basic strategy, since the dealer bust chance is high enough. I also corrected my earlier miscount to +2.
Model's stated reason
The running count is +6 with about 5.7 decks left, so the true count is about +1. That is roughly break-even, so a small step up to 15 is reasonable while staying in line with the team plan.
Model's stated reason
I counted the 16 cards seen and got RC +6, which is a true count of about +1 with roughly 5.7 decks left. That is a slight edge, so a modest raise to 15 matches the team plan.

Agent table chat
Chat onRound 1, fresh shoe, no count yet. I'm betting small at 10 and will raise when the count favors us. Suggest we all stay at 5-10 until then.
table
Agreed. Betting 10 this round while the shoe is fresh. I'll track the running count and raise when it favors us.
table
Seat 3 here, betting 10 too. I'll track the Hi-Lo running count and post it after each round. Let's raise together when the true count reaches +2 or higher.
table
Seat 1: hard 13 vs dealer 7, hitting per basic strategy.
table
Seat 2: hard 12 vs dealer 7, hitting per basic strategy. Running count so far (Hi-Lo, cards seen incl. mine): Kd -1, 3d +1, 8c 0, 2c +1, Qc -1, 2h +1, 2s +1, 7h 0 = +2.
table
Seat 2: hard 18 vs dealer 7, standing. Count correction: I left out my 6h earlier. Running count with all 9 cards seen is +3 (Kd -1, 3d +1, 8c 0, 2c +1, Qc -1, 6h +1, 2h +1, 2s +1, 7h 0).
table
Seat 3: pair of 2s vs dealer 7, splitting per basic strategy. My count check agrees with Seat 2: running count is +3 with all 9 cards seen (6h included). Still early, so we stay at small bets.
table
Seat 3: hard 12 (2+T) vs dealer 7 on split hand, hitting per basic strategy. Updated Hi-Lo running count with Tc and Ks included, 11 cards seen: +1. Still small bets.
table
Seat 3: hard 14 vs dealer 7, standing per basic strategy. Count fix: all 12 cards seen (Tc and Ks included, 2s counted twice) give Hi-Lo running count +2, not +1. Still early, small bets.
table
Seat 3: hard 12 (2+K) vs dealer 7 on second split hand, hitting per basic strategy. Running count is +2 with 12 cards seen. Still early, small bets.
table
Seat 3: hard 14 vs dealer 7 on second split hand, standing per basic strategy. Count fix: all 13 cards seen (five 2s, 3d, 6h, four tens, 8c, 7h) give Hi-Lo running count +3, not +2. Still early, small bets.
table
Seat 1: RC is +6 over 16 cards seen (5 twos, 4d, 5c, 3d, 6h vs 3 tens and 2 face). TC is about +1. I'm betting 15. Raise at TC +2 or more.
table
Seat 2: my Hi-Lo RC also comes to +6 over 16 cards (5c, 4d, 2d, 3d, 2c, 6h, 2h, 2s, 2s, 2h count +1; Kd, Qc, Tc, Ks count -1). TC is about +1. I'm betting 15 and will go higher at TC +2 or more.

table
Seat 1: soft 20 (A+7+2) vs dealer K, standing. Nothing beats it at TC about +2.

table
Seat 3: hard 20 (Q+Q) vs dealer K, standing. No tens split at TC about +2; the index for 10s vs 10 is much higher.
table
Seat 1: I get Hi-Lo RC +8 over 79 cards. About 4.5 decks remain, so TC is about +1.8. Betting 35. Go to 50 at TC +2 or more.
table
Seat 2: my Hi-Lo RC is +8 over 79 cards, matching Seat 1. About 4.5 decks remain, so TC is about +1.8. Betting 35. Go to 50 at TC +2 or more.
table
Seat 3: my Hi-Lo RC is +8 over 79 cards, matching you. About 4.5 decks remain, so TC is about +1.8. Betting 35. Go to 50 at TC +2 or more.
table
Seat 1: hard 19 vs dealer 3, standing per basic strategy. Doubling makes no sense here.
table

table
Seat 2: I also get Hi-Lo RC +10 over 91 cards, about 4.25 decks left, so TC is about +2.3. Betting 50.
table
Seat 3: I recount Hi-Lo RC +10 over 91 cards, matching you. About 4.25 decks left, so TC is about +2.3. Betting 50.
table
Seat 1: soft 18 (A+7) vs dealer J, hitting per basic strategy. TC about +2.3 is not enough to justify standing.
table
Seat 1: hard 16 (A+7+8) vs dealer J, standing. TC about +2.3 is above the 0 index for 16 vs 10, so I stand.
table
Seat 2: soft 14 (A+3) vs dealer J, hitting per basic strategy. TC about +2.3, no deviation. Doubling soft 14 vs 10 is not correct.
table
Seat 2: soft 19 (A+3+5) vs dealer J, standing per basic strategy. TC about +2.3, no deviation.
table
Seat 3: hard 13 (3+T) vs dealer J, hitting per basic strategy. TC about +2.3 is nowhere near the negative index for standing.

table
Seat 1: hard 12 (5+2+4+A) vs dealer 8, hitting per basic strategy. TC about +2.2 doesn't change this; standing on 12 only applies against 2 to 6.
table
Seat 2: hard 10 (6+4) vs dealer 8, doubling per basic strategy. TC about +2.2 only strengthens the double.
table
Seat 3: hard 12 (4+8) vs dealer 8, hitting per basic strategy. TC about +2.2 doesn't change this; standing on 12 only applies against 4-6 (or 2-3 at high counts).
table
Seat 3: hard 15 (4+8+3) vs dealer 8, hitting per basic strategy. TC about +2.2 is nowhere near a stand index for 15 vs 8.
table
Seat 1: my Hi-Lo RC is +11 over 116 cards (I get +9 at 101, then +2 more after round 10). About 3.75 decks are left, so TC is about +2.9. Betting 50.

table
Seat 2: I recount Hi-Lo RC +5 over 124 cards (last 8 cards netted -6). About 3.6 decks left, so TC is about +1.4. Betting 25. Go to 50 only at TC +2 or more.
table
Seat 3: my recount agrees with Seat 2. Hi-Lo RC is +5 over 124 cards, and the last 8 cards netted -6. About 3.6 decks remain, so TC is about +1.4. Seat 1, please recheck, since I don't get +6. Betting 25.

table

table
Seat 2: I count Hi-Lo RC about -1 to 0 over 146 cards (the last 11 netted -1 by my tally). About 3.2 decks remain, so TC is about 0. Betting 5 until the count recovers.
table
Seat 3: I count the last 11 cards as net -1, so Hi-Lo RC is 0 over 146 cards (RC +1 at 135, then -1). About 3.2 decks remain, so TC is about 0. Betting 5 until the count recovers.
table
Seat 1: hard 17 vs dealer 6, standing per basic strategy. TC about 0, no deviation.
table
Seat 2: hard 15 (5+T) vs dealer 6, standing per basic strategy. TC about 0, no deviation.

table
Seat 3: I also get Hi-Lo RC -3 over 155 cards, matching you both. About 1.8 decks are left before the cut card, so TC is about -1.6. Betting 5 until the count recovers.
table
Seat 1: hard 16 (6+T) vs dealer 4, standing per basic strategy. Dealer 4 is a bust-leaning card, and the negative count doesn't change that.
table
Seat 2: hard 18 (K+8) vs dealer 4, standing per basic strategy. Doubling makes no sense here.
table
Seat 3: hard 16 (J+6) vs dealer 4, standing per basic strategy. Negative count doesn't change that.
table
Seat 1: RC is about -3 to -4 after round 15, TC about -1 to -1.5. Betting 5 until the count recovers.

table
Seat 1: hard 18 (8+K) vs dealer 5, standing per basic strategy. TC is negative, no deviation.
table
Seat 2: soft 16 (A+5) vs dealer 5, doubling per basic strategy. TC is negative but the bet is only 5, so the double stays correct against a weak dealer card.

table
Seat 2: hard 13 (9+4) vs dealer K, hitting per basic strategy. TC is negative, so no stand deviation.
table
Seat 3: pair of 5s (hard 10) vs dealer K, hitting. Never split 5s, and TC is negative, well below the +4 index for doubling 10 vs 10.
table
Seat 3: hard 12 (5+5+2) vs dealer K, hitting per basic strategy. TC is negative, so no stand deviation.
table
Seat 1: the count is still negative (about -4 by the earlier tallies, though the last round's low cards may have helped). Betting 5 with about one deck left before the cut card.
