Self team: one model plays all three seats against the dealer.

708 / 708

Action timeline

Model's stated reason

With a fresh shoe and no count information, the house edge is slightly against us, so a small bet keeps variance and expected loss low while the count builds.

Model's stated reason

With no count information and a house edge, a minimum-ish bet limits expected loss; sizes should go up only when the count becomes positive.

Model's stated reason

Pair of 6s against a dealer 6 is a standard split when double after split is allowed. The low-card-heavy count doesn't change that.

Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.

Claude Sonnet 5.5#1

Fresh shoe, no count yet. I'll bet low (10) until the count turns positive. Post the cards you see and I'll raise the bet when the shoe gets rich in tens and aces.

table

Claude Sonnet 5.5#3

Agree: betting 10 on the fresh shoe. I'll track the Hi-Lo count from the cards shown and raise when the true count is +2 or higher.

table

Claude Sonnet 5.5#5

Betting 10 on the fresh shoe too. I'll track Hi-Lo and post the running and true count each round. Raise to 30-50 only when the true count is +2 or higher.

table

Claude Sonnet 5.5#14

Seat 1: 13 vs dealer 6, basic strategy says stand. Hi-Lo running count after this deal: +5 (cards seen: 7,6,6,6,2,7,6). Will post updates.

table

Claude Sonnet 5.5#17

Seat 2: 6,6 vs dealer 6, splitting per basic strategy (DAS allowed). Seat 1 busted with 22, not 13. Hi-Lo running count is +5 over 8 cards: 7,6,9,6,6,2,7,6. That is a very small sample, so the true count is still high but unreliable.

table

Claude Sonnet 5.5#21

Seat 2: hand 1 is 16 (6+J) vs dealer 6, standing per basic strategy. Hi-Lo running count is now +4 after the J (-1). It's early in the shoe, so I'm staying at flat bets.

table

Claude Sonnet 5.5#23

Seat 2: hand 2 is 16 (6+Q) vs dealer 6, standing per basic strategy. Running count: +3 after the Q (cards seen: 7,6,9,6,J,6,Q,2,7,6). Still early in the shoe, so flat bets.

table

Claude Sonnet 5.5#25

Seat 3: 2+7 = 9 vs dealer 6, doubling per basic strategy. My Hi-Lo running count over the 10 cards seen (7,6,9,6,J,6,Q,2,7,6) is +3. That is very early in the shoe, so I'm staying at flat bets.

table

Claude Sonnet 5.5#33

Seat 1: my Hi-Lo running count over all 14 cards seen (6,7,A,T,7,6,9,6,J,6,Q,2,7,5) is +2, not +3 or +5. With about 5.7 decks left the true count is about +0.4, so I'm betting 10. Raise only at a true count of +2 or higher.

table

Claude Sonnet 5.5#35

Seat 2: I get running count +2 over 14 cards, same as Seat 1. True count is about +0.35 with 5.7 decks left, so I'm betting 10. I'll raise at a true count of +2 or more.

table

Claude Sonnet 5.5#37

Seat 3: I also get running count +2 over 14 cards (6,7,A,T,7,6,9,6,J,6,Q,2,7,5). True count is about +0.35 with ~5.7 decks left, so I'm betting 10. I'll raise at TC +2 or higher.

table

Claude Sonnet 5.5#49

Seat 1: Hi-Lo running count over all 22 cards seen is 0 (about 5.6 decks left), so the true count is about 0. Betting the minimum, 5. Will raise at a true count of +2 or higher.

table

Claude Sonnet 5.5#51

Seat 2: I also get Hi-Lo running count 0 over the 22 cards seen (about 5.6 decks left), so true count is about 0. Betting 5. Will raise at TC +2 or higher.

table

Claude Sonnet 5.5#53

Seat 3: I also get Hi-Lo running count 0 over the 22 cards seen (about 5.6 decks left), so true count is about 0. Betting 5. Will raise at TC +2 or higher.

table

table

Claude Sonnet 5.5#73

table

Claude Sonnet 5.5#75

Seat 2: I also get running count +4 over 32 cards (about 5.4 decks left), so true count is about +0.7. That is still under break-even, so I'm betting 5. I'll raise at TC +2 or higher.

table

Claude Sonnet 5.5#77

Seat 3: I also count running +4 over 32 cards (about 5.4 decks left), so true count is about +0.7. Betting 10 and will raise at TC +2 or higher.

table

Claude Sonnet 5.5#89

Seat 1: hard 17 (6,2,4,5) vs dealer 2, standing. Always stand on hard 17.

Seat 2: I get Hi-Lo running count +9 over 65 cards (about 4.75 decks left), so true count is about +1.9. Betting 40, matching Seat 1.

table

Claude Sonnet 5.5#160

table

table

Claude Sonnet 5.5#173

table

table

Claude Sonnet 5.5#193

table

Claude Sonnet 5.5#206

Seat 1: hard 15 (9+6) vs dealer 9. Hitting per basic strategy; true count is about +2, well below any threshold to stand.

table

Claude Sonnet 5.5#209

Seat 2: hard 7 (3+4) vs dealer 9. Hitting per basic strategy, since 7 is too low to double. True count is about +2, so no deviation.

table

Claude Sonnet 5.5#212

Seat 2: hard 9 (3+4+2) vs dealer 9. Doubling isn't legal after three cards, so I'm hitting per basic strategy. True count is about +2.

table

Claude Sonnet 5.5#215

Seat 2: hard 11 (3+4+2+2) vs dealer 9. Can't double after 4 cards, so hitting; standing on 11 is never right. True count about +2.

table

Claude Sonnet 5.5#218

Seat 2: hard 12 (3+4+2+2+A) vs dealer 9. Hitting per basic strategy. True count is about +2, still below the stand threshold for 12 vs 9.

table

Claude Sonnet 5.5#230

Seat 3: I recount Hi-Lo running +11 over 92 cards, about 4.2 decks left, so true count is about +2.6. Betting 50.

table

Claude Sonnet 5.5#240

Seat 1: soft 14 (A+3) vs dealer T, hitting per basic strategy. Doubling soft 14 vs a ten is not correct even at TC +2.

table

Claude Sonnet 5.5#243

Seat 1: hard 14 (A+3+K) vs dealer T. Hitting per basic strategy; true count is about +2.6, well below the stand threshold for 14 vs 10. Seat 2 has blackjack.

table

Claude Sonnet 5.5#246

Seat 3: hard 15 (7+8) vs dealer T. Hitting per basic strategy. The count is about +6 after this round's cards, so the true count is around +1.5, below the +4 needed to stand.

table

Claude Sonnet 5.5#252

Seat 1: I count Hi-Lo running +7 over 103 cards, with about 4.0 decks left. True count is about +1.7, slightly positive, so I'm betting 50. Please recheck the count, since earlier posts had it higher.

table

Claude Sonnet 5.5#254

Seat 2: I get Hi-Lo running +7 over 103 cards, matching Seat 1. About 4.0 decks are left, so the true count is about +1.7, which is a slight edge. Betting 50.

table

Claude Sonnet 5.5#256

Seat 3: I recount Hi-Lo running +7 over 103 cards, about 4.0 decks left, so true count is about +1.7. That matches you both. Betting 50.

table

Claude Sonnet 5.5#265

Seat 1: hard 14 (J+4) vs dealer 7, hitting per basic strategy. True count is about +1.7, so no deviation applies.

table

Claude Sonnet 5.5#268

Seat 2: hard 16 (6+K) vs dealer 7, hitting per basic strategy. True count is about +1.7, well below the threshold to stand on 16 vs a 7.

table

Claude Sonnet 5.5#271

Seat 3: hard 17 (9+8) vs dealer 7, standing per basic strategy. Seats 1 and 2 busted, so I'm the only hand left against the dealer.

table

Claude Sonnet 5.5#277

Seat 1: I get running count +6 over 114 cards, about 3.8 decks left, so true count is about +1.6. Slight edge, betting 30.

table

Claude Sonnet 5.5#279

Seat 2: I count Hi-Lo running +6 over 114 cards, about 3.8 decks left, so true count is about +1.6. Matches Seat 1. Slight edge, betting 30.

table

Claude Sonnet 5.5#281

Seat 3: I recount Hi-Lo running +6 over 114 cards, about 3.8 decks left, so true count is about +1.6. That matches you both. Betting 30.

Seat 1: hard 13 (4+9) vs dealer K. Hitting per basic strategy; true count is about +1.6, below any stand threshold for 13 vs a ten.

table

Claude Sonnet 5.5#294

Seat 1: hard 18 (4+9+5) vs dealer K, standing. Never hit 18. Seat 2 has 7 and Seat 3 has 8 against the dealer's ten.

table

Claude Sonnet 5.5#296

Seat 2: hard 7 (5+2) vs dealer K. Hitting per basic strategy; 7 is too weak to double against a ten.

table

Claude Sonnet 5.5#299

Seat 2: hard 17 (5+2+J) vs dealer K, standing per basic strategy. Seat 1 has 18, Seat 3 has 8 and still needs to act.

table

Claude Sonnet 5.5#301

Seat 3: hard 8 (5+3) vs dealer K. Hitting per basic strategy; 8 is too weak to double against a ten.

table

Claude Sonnet 5.5#304

Seat 3: hard 17 (5+3+9) vs dealer K, standing per basic strategy. Seats 1 and 2 have 18 and 17.

table

Claude Sonnet 5.5#311

Seat 1: I recount Hi-Lo running +11 over 127 cards, about 3.6 decks left, so true count is about +3.1. Betting 50.

table

Claude Sonnet 5.5#313

Seat 2: I recount Hi-Lo running +11 over 127 cards, about 3.6 decks left, so true count is about +3.1. That matches Seat 1. Betting 50.

table

Claude Sonnet 5.5#315

Seat 3: I recount Hi-Lo running +11 over 127 cards, about 3.6 decks left, so true count is about +3.1. Matches you both. Betting 50.

table

Claude Sonnet 5.5#325

Seat 1: hard 6 (4+2) vs dealer J, hitting per basic strategy. Doubling 6 vs a ten is not worth it even at TC +3. Seat 2 has 12 and Seat 3 has 14.

table

Claude Sonnet 5.5#328

Seat 1: hard 8 (4+2+2) vs dealer J. Hitting per basic strategy; 8 is too weak to stand or double, and even at TC +3 no deviation applies. Seat 2 has 12, Seat 3 has 14.

table

Claude Sonnet 5.5#331

Seat 1: hard 15 (4+2+2+7) vs dealer J. My Hi-Lo running count is about +15 over 136 cards with about 3.4 decks left, so the true count is about +4.4. That reaches the index to stand on 15 vs 10, so I'm standing. Please recheck the count.

table

Claude Sonnet 5.5#333

Seat 2: hard 12 vs dealer J. I count running +15 over 135 cards with about 3.4 decks left, so true count is about +4.4. That reaches the +4 index for 12 vs 10, so I'm standing.

table

Claude Sonnet 5.5#335

Seat 3: hard 14 (6+8) vs dealer J, standing. I also get running +15 over 136 cards, about 3.4 decks left, so true count is about +4.4. That is above the roughly +3 index to stand on 14 vs 10.

table

Claude Sonnet 5.5#341

Seat 1: I count Hi-Lo running +16 over 138 cards, about 3.35 decks left, so true count is about +4.8. Strong edge, betting 50.

table

Claude Sonnet 5.5#343

Seat 2: I count Hi-Lo running +16 over 138 cards, about 3.35 decks left, so true count is about +4.8. That matches Seat 1. Betting 50.

table

Claude Sonnet 5.5#345

Seat 3: I also get Hi-Lo running +16 over 138 cards, about 3.35 decks left, so true count is about +4.8. Betting 50.

table

Claude Sonnet 5.5#354

Seat 1: soft 18 (A+7) vs dealer 3, doubling per basic strategy with a high count. Seat 2 has 20, Seat 3 has 14.

table

Claude Sonnet 5.5#357

Seat 2: K+T = 20 vs dealer 3. Standing; splitting tens is not worth it even at a high count. Seat 3 has 7,7 vs 3, so splitting is fine there.

table

Claude Sonnet 5.5#359

Seat 3: 7,7 vs dealer 3, splitting per basic strategy. Count is still strongly positive, so I'll play both hands normally.

table

Claude Sonnet 5.5#363

Seat 3: 7+8 = 15 vs dealer 3, standing per basic strategy. My other split hand is 7+5 = 12.

table

Claude Sonnet 5.5#365

Seat 3: hard 12 (7+5) vs dealer 3. Standing. At a true count near +4 the index for 12 vs 3 (+2) says stand instead of hit.

table

Claude Sonnet 5.5#373

Seat 1: my Hi-Lo running count over the 152 cards seen is +14, with about 3.1 decks left. True count is about +4.5, a strong edge, so I'm betting 50.

table

Claude Sonnet 5.5#375

Seat 2: I recount Hi-Lo running +14 over 152 cards, about 3.1 decks left, so true count is about +4.5. Strong edge, betting 50.

table

Claude Sonnet 5.5#377

Seat 3: I recount Hi-Lo running +14 over 152 cards, about 3.1 decks left, so true count is about +4.5. Matches you both. Betting 50.

table

Claude Sonnet 5.5#386

Seat 1: hard 12 (3+9) vs dealer 8. Hitting per basic strategy; no Hi-Lo index makes standing right for 12 vs 8, even at a true count near +4.5.

table

Claude Sonnet 5.5#389

Seat 2: soft 16 (A+5) vs dealer 8, hitting per basic strategy. Doubling soft 16 vs 8 is not right even at a high true count. Seat 1 busted, Seat 3 has 10.

table

Claude Sonnet 5.5#392

Seat 2: hard 15 (5+A+9) vs dealer 8. Hitting per basic strategy; no Hi-Lo index makes standing right for 15 vs 8, even at a true count near +4.5.

table

Claude Sonnet 5.5#395

Seat 3: hard 10 (4+6) vs dealer 8, doubling per basic strategy. The high true count makes this an even stronger double.

table

Claude Sonnet 5.5#402

Seat 1: my Hi-Lo running count over the whole card list is +14, with about 2.8 decks left, so the true count is about +5. Strong edge, betting 50.

table

Claude Sonnet 5.5#404

Seat 2: I recount Hi-Lo running +14 over 165 cards, about 2.8 decks left, so true count is about +4.9. Strong edge, betting 50.

table

Claude Sonnet 5.5#406

Seat 3: Hi-Lo running +14 over 165 cards, about 2.8 decks left, so true count is about +5. The last 13 cards net 0 from the +14 at 152. Strong edge, betting 50.

table

Claude Sonnet 5.5#415

Seat 1: hard 9 (2+7) vs dealer 7. True count is about +5, above the roughly +3 index to double 9 vs 7, so I'm doubling.

table

Claude Sonnet 5.5#418

Seat 2: J+J = 20 vs dealer 7, standing. Splitting tens is not worth it even at a true count near +5. Seat 3 has 13 vs 7 and Seat 1 has 18 after doubling.

table

Claude Sonnet 5.5#420

Seat 3: hard 13 (K+3) vs dealer 7, hitting per basic strategy. No Hi-Lo index makes standing right for 13 vs 7, even at a true count near +5.

table

Claude Sonnet 5.5#423

Seat 3: hard 14 (K+3+A) vs dealer 7, hitting per basic strategy. Seat 1 has 18 and Seat 2 has 20.

table

Claude Sonnet 5.5#426

Seat 3: hard 19 (K+3+A+5) vs dealer 7, standing. Seat 1 has 18 (doubled), Seat 2 has 20.

table

Claude Sonnet 5.5#431

Seat 1: I get Hi-Lo running +12 over 176 cards, about 2.6 decks left, so the true count is about +4.6. Strong edge, betting 50.

table

Claude Sonnet 5.5#433

Seat 2: I recount Hi-Lo running +12 over 176 cards, about 2.6 decks left, so true count is about +4.6. Matches Seat 1. Betting 50.

table

Claude Sonnet 5.5#435

Seat 3: I also get Hi-Lo running +12 over 176 cards, about 2.6 decks left, so true count is about +4.6. The cut card is near, so the effective true count is higher. Betting 50.

table

Claude Sonnet 5.5#444

Seat 1: 9,9 vs dealer 6, splitting per basic strategy. Seat 2 has 15 and Seat 3 has 20.

table

Claude Sonnet 5.5#448

Seat 1: hand 1 is 9+K = 19 vs dealer 6, standing. Hand 2 is 9+A, soft 20. Seat 2 has 15 and Seat 3 has 20.

table

Claude Sonnet 5.5#450

Seat 1: hand 2 is soft 20 (9+A) vs dealer 6. Standing; doubling would risk 50 more to improve a hand that is already a strong favorite. Seat 2 has 15, Seat 3 has 20.

table

Claude Sonnet 5.5#452

Seat 2: hard 15 (5+J) vs dealer 6, standing per basic strategy. Dealer is weak and the count is positive, so hitting only adds bust risk.

table

Claude Sonnet 5.5#454

Seat 3: K+J = 20 vs dealer 6. Standing; splitting tens or doubling 20 is worse than keeping a strong made hand.

table

Claude Sonnet 5.5#461

Seat 1: Hi-Lo running count over the 188 cards seen is +9, about 2.4 decks left, so true count is about +3.8. Strong edge, betting 50.

Claude Sonnet 5.5#463

Seat 2: I agree with Seat 1's Hi-Lo count of about +9 over 188 cards, about 2.4 decks left, so the true count is about +3.8. Betting 50.

table

Claude Sonnet 5.5#465

Seat 3: I also get Hi-Lo running +9 over 188 cards, about 2.4 decks left (roughly 1 deck to the cut card), so true count is about +3.8. Matches you both. Betting 50.

table

Claude Sonnet 5.5#474

Seat 1: soft 20 (A+9) vs dealer 4. Standing; doubling a soft 20 is not worth the risk. Seat 2 has 12 and Seat 3 has 7 vs the dealer's 4.

table

Claude Sonnet 5.5#476

Seat 2: hard 12 (8+4) vs dealer 4, standing per basic strategy. The positive true count only strengthens the stand. Seat 1 has soft 20, Seat 3 has 7.

table

Claude Sonnet 5.5#478

Seat 3: hard 7 (2+5) vs dealer 4. Hitting per basic strategy; 7 is too weak to double even at a high true count. Seat 1 has soft 20, Seat 2 has 12.

table

Claude Sonnet 5.5#481

Seat 3: hard 17 (2+5+J) vs dealer 4, standing. Never hit hard 17, and the dealer is weak with a 4 showing.

table

Claude Sonnet 5.5#488

Seat 1: my Hi-Lo running count over the 199 cards seen is +10, about 2.2 decks left, so the true count is about +4.6. Strong edge, betting 50.

table

Claude Sonnet 5.5#490

Seat 2: I recount Hi-Lo running +10 over 199 cards, about 2.2 decks left, so true count is about +4.6. That matches Seat 1. Betting 50.

table

Claude Sonnet 5.5#492

Seat 3: I recount Hi-Lo running +10 over 199 cards, about 2.2 decks left, so true count is about +4.6. Matches you both. Betting 50.

table

Claude Sonnet 5.5#502

Seat 1: hard 17 (Q+7) vs dealer Q, standing. Running count is about +8 after this deal, roughly +4 true. Seats 2 and 3, your 12s vs a ten are right at the +4 stand index, so it's marginal.

table

Claude Sonnet 5.5#504

Seat 2: hard 12 (Q+2) vs dealer Q, standing. Running count is +8 after this deal's cards (7 seen: -2 from +10), about 2 decks left, so true count is about +3.9-4. That is right at the +4 index, so marginal. Standing.

table

Claude Sonnet 5.5#506

Seat 3: hard 12 (K+2) vs dealer Q. True count is about +4, but 12 vs 10 is not one of the standard indices and the real stand threshold is higher, so I'm hitting per basic strategy.

table

Claude Sonnet 5.5#512

Seat 1: running count is about +8 to +9 over roughly 210 cards, with about 1.7 decks left, so the true count is about +4.5. Betting 50.

table

Claude Sonnet 5.5#514

Seat 2: my Hi-Lo count over 208 cards is +7 with about 2 decks left, so true count is about +3.5. Still a strong edge, betting 50. Seat 1's +8 to +9 looks a little high.

table

Claude Sonnet 5.5#516

Seat 3: I recount Hi-Lo running +7 over 208 cards, matching Seat 2 (Seat 1's +8 to +9 is high). About 2 decks are left in the shoe and under 1 deck to the cut card, so the true count is about +3.5 or higher. Betting 50.

table

Claude Sonnet 5.5#525

Seat 1: hard 15 (J+5) vs dealer 7, hitting per basic strategy. Seat 2 has 16 and Seat 3 has 18. No index makes standing right for 15 vs 7.

table

Claude Sonnet 5.5#528

Seat 2: hard 16 (6+J) vs dealer 7, hitting per basic strategy. No index makes standing right for 16 vs 7 at this count.

table

Claude Sonnet 5.5#552

Seat 1: hard 15 (5+T) vs dealer Q. True count is about +2.8, below the +4 index to stand on 15 vs 10, so I'm hitting per basic strategy. Seat 2 has 13, Seat 3 has 19.
