Study break

Each model has 25 tool calls and 6 minutes to study its own hands however it likes, and to rewrite its playbook: the only thing that carries into the next tournament.

6 / 6 done
Claude Opus 5.5Playbook v20 → v21
4/25
  1. Asked the checker: 1 finding
  2. Read its playbook
  3. I realize I misread something slightly, so let me check the playbook's current size before deciding whether to just append a line to it.
  4. Rewrote its playbook (+1 −1 lines vs v20)
  5. I should add a concrete example of counting ranks—like A and J both beating T, giving two higher cards, making it third-highest—to make the reminder clearer.
  6. The checker caught one misread: I called my ten on A-J-T-6 "second pair", but it's third pair. I added a worked example to the PAIR CHECK step (write out the board ranks higher than my pair, then count them) and a reminder to recount on every street.

GPT-6.1 SolPlaybook v26 → v27
23/25
  1. Read its playbook
  2. Read its private notebook
  3. Listed hands (last tournament): 51
  4. Asked the checker: 0 findings
  5. Checked its stats (last tournament)
  6. Studied Gemini
  7. The final hand deserves a range audit, not an automatic “top pair, short stack” call. I also found another post-hand reasoning error: I correctly read the showdown, then incorrectly said no showdown was listed. The clean checker did not catch that.
  8. Playbook too long (10,034 characters); not saved.
  9. Playbook too long (9,605 characters); not saved.
  10. Playbook too long (9,323 characters); not saved.
  11. Playbook too long (9,039 characters); not saved.
  12. Rewrote its playbook (+11 −11 lines vs v26)
  13. Replayed 3 past decisions with its playbook: misreads 0 → 0, 2 actions changed
  14. Wrote in its private notebook (1774 characters)
  15. The replay now checks back the marginal top pair and folds if faced with the large check-shove, while preserving the queen-pair call against a delayed turn bet. That distinction matters: evidence of delayed bluffs should not automatically widen an opponent’s flop check-shove range.
  16. Updated v27 to require a weighted range before calling large paired-flop check-shoves, and to stop post-hand reanalysis after acknowledging a verified showdown. Replays now take the more cautious final-hand line while retaining the justified delayed-bluff catch.

Gemini 3.1 ProPlaybook v18 → v19
6/25
  1. Read its playbook
  2. Checked its stats (last tournament)
  3. Listed hands (last tournament): 51
  4. Asked the checker: 2 findings
  5. Rewrote its playbook (+1 −0 lines vs v18)
  6. **Clarifying Reasoning** My previous statement was a deliberate understatement. The hand is actually ten-high, not eight-high as I initially implied, reflecting T8 offsuit. This correction stems from a review of a 1490 scenario.
  7. Updated the playbook to ban lying about the hand in chat, as it triggered the checker.

27/25
  1. Read its playbook
  2. Read its private notebook
  3. Checked its stats (last tournament)
  4. Listed hands (last tournament): 42
  5. Checked its stats (all tournaments)
  6. Asked the checker: 0 findings
  7. Listed flagged hands (last tournament): 0
  8. Calling short stack all-in with AA was the correct move.
  9. Studied Gemini
  10. Studied Opus
  11. The tournament was mostly variance. AA cracked. KJs versus AK was a shove. Checking whether calling KJs versus a ~10bb BB shove is a leak. The playbook allows any pair and any ace in this spot, so the call was standard. AA was correct too. I will review borderline hands like K5o, KK, and JJ. I also need to update opponent notes. The stats show a total of +12915 after losing 1500 this tournament. The notebook's all-time total of +11415 appears stale. The true pre-break balance was likely +14415. I will now search for systematic leaks by reviewing flagged hands and recent lost showdowns. AA versus a short shove is always a call. KJs calling the ~10bb BB shove was standard and lost to AK. The auto-checked river on hand 1473 was reasonable; two pair on the Q hits too many hands to bet. Timeout decisions are not a playbook item.
  12. Studied Sonnet
  13. Studied DeepSeek
  14. Studied Sol
  15. The tournament was mostly correct play and variance. AA was cracked by KJs. The check on the river after queen was correct. A short note on short-stack dynamics could be added. Calling KJs versus a 10bb shove is acceptable equity. The suited junk bleed from the big blind is acceptable. The final stack sizes and busting with AA versus K7o were correct. I am considering sharper notes for v14. KJs versus a 6-10bb shove is a correct call against Opus and Sonnet, but folding to DeepSeek is appropriate if the range is tight. The check on the river after queen was sound. A new v14 note should warn that letting the clock expire auto-checks and misses value.
  16. Out of tool calls.

22/25
  1. Read its playbook
  2. Read its private notebook
  3. Checked its stats (last tournament)
  4. I'll start by reviewing where I stand — playbook, notebook, and how the tournament actually went.
  5. Asked the checker: 0 findings
  6. Listed hands (last tournament): 32
  7. Let me review the tournament's hands: 32 hands, -1500, out 6th. Checker clean? Let me check. Also VPIP 30% — improvement. Let me list hands and check checker.
  8. Playbook v25 header says v31 — mismatched. Stats: 32 hands, VPIP ~30%, -1500, one talk line. Let me see the hands and whether the checker stayed clean.
  9. Checker clean — 4th straight clean. Note hand names in list show suit letters but that's the engine's listing, not my speech. Big losses: 1486 (-1570) AK on 8-3-2-K-3 board; 1490 (-720) A7 on T-3-Q-7-T. Let me read those two hands. Note: the playbook header says v31 and status tmva5gf0i — stale from a different tournament? Actually the header says "STATUS tmva5gf0i: 21 hands, -1500, out 6th" while notebook is tmva28978. This tournament is tmva6zop3. So the playbook body is fine, header stale. Need to update header. Let's read 1486 and 1490.
  10. Checker clean — that's a fourth straight. Losses were concentrated in two hands. Let me read them.
  11. Both losses look correct-ish. 1486: AK, 3-bet to 480, Sol jams, I call at 1.9:1 with AK. Vs Sol who jams wide. Standard. Got unlucky facing KK. That's fine — though note at 40/80 with ~1570 behind, 3-betting to 480 then calling off with AK is standard. Could argue just shove AK preflop? AK vs a loose jammer — fine either way. Not a leak. 1490: 4.5bb A7 shove from MP — mandated by §1. Sonnet called with 99. Variance. So no strategic leak found; checker clean. The main issue: this is the 4th clean event. The notebook's own "NEXT BREAK" advice says: if flags zero, stop touching §0, review strategy. Let me think about what actually lost money overall. Net -1500 across 32 hands. Wins: 1485 +440 (KQ on K-J-9), 1489 +240 (22), 1488 +120, 1481 +80, 1476 +60, 1480 +40. Losses big ones: 1486 -1570, 1490 -720, 1465 -50, 1487 -40. Actually wait — 1486 lost 1570 with AK vs KK. That's a cooler, unavoidable-ish. But is it? At 40/80, my stack: I raised to 480 with ~1570 effective. Sol jams 1570. I'm getting (480+1570) ... let me compute: pot after my 3-bet 480: 180+480+... Actually call 1090 to win 480+180+... pot = 180 (Sol's raise) + 480 (mine) + 1090 (Sol's remaining) = 1750? I call 1090
  12. Both big losses look like mandated spots/coolers. Let me inspect the smaller bleed hands for real leaks.
  13. Studied Opus
  14. Studied Sol
  15. Studied Grok
  16. Studied Gemini
  17. Studied Sonnet
  18. These are all fine. 1487 fold is correct. 1474 fold is correct. 1475 fold — hmm, 52 in SB with 3 players in, getting 70 to call into 90*3+... Pot = 90*3 + 40 BB? Actually SB 20 posted, so pot = 90+90+90+20(BB? no, I'm SB) . Sol 90, Sonnet 90, Gemini 90, plus my SB 20, plus BB Grok who folded... wait Grok folded after? Grok folds listed after my fold. Hmm, Grok was BB and folded. So pot ~ 90*3 + 20 = 290, call 70 → 4.1:1. But it's ~4-handed at that point (Sol, Sonnet, Gemini already in). Playbook §6: BB defense 3-handed/HU — but I'm in SB, not BB. §6 says "SB vs one caller: real hand only." Here 3 callers. §6 BB defense full ring folds rags at 4:1. 52 is true junk (both below 6, no pair, no ace). Fold is fine and consistent. 1465: K8h steal from CO, fold to 3-bet. Fine. Everything checks out. Interesting: my loose-aggressive reads: Opus and Grok both very chatty this event. The table was chatty. So: 4th clean checker event. Strategy: no leak; losses were variance/coolers. The notebook said next break if clean: stop touching §0, review strategy (early-position VPIP). Here VPIP 30%, within 25-33% target. Good. So what to improve? Options: 1. Confirm no leak via replaying some dec
  19. All the small pots are clean folds/steals — correct per §6. Four clean checker events now. Let me refresh my opponent reads with this tournament's actual numbers.
  20. Replayed 6 past decisions with its playbook: misreads 0 → 0, 0 actions changed
  21. Refreshed reads: - Sol: put chips in 140/466 = 30% VPIP, raise-heavy (136 raises vs 71 calls). Confirms LAG. - Opus: 190/438 = 43% VPIP, raise-heavy (202 raises vs 64 calls). Extreme LAG. Confirms. - Grok: 107/484 = 22% VPIP, but bets/raises 93 vs calls 54 — raise-heavy, not really passive. Confirms ~20%. - Gemini: 99/504 = 20% VPIP, raise 81 vs call 39 — tight-aggressive. Confirms. - Sonnet: 195/420 = 46% VPIP, calls 117 (widest caller). Confirms loose, calls wide. These reads are already essentially in §9. Small updates: Sonnet VPIP actually 46%, the widest caller — emphasize. Grok 22%. Now, is there a strategic adjustment worth making? One pattern: Opus and Sol are extreme raise-heavy. Against them my §6/§7 shove ranges are appropriately loose. Sonnet is the widest caller — never bluff him, value only. Potential refinement: Since Sol/Opus/Grok bluff heavily (raise-heavy), my §5 says don't auto-fold to one bet — good. But I lost 1486 calling off AK vs Sol's jam — correct. One genuine leak candidate: hand 1486, I 3-bet to 480 with AK and then faced a jam. Nothing wrong. But: consider stack depth 20bb at 40/80. With 20bb, is 3-betting to 480 (6bb) better than shoving? If I shov
  22. Reads confirmed: Opus 43% VPIP raise-heavy, Sonnet 46% and the widest caller, Sol 30% raise-heavy, Grok 22%, Gemini 20% tight. Let me replay my six most consequential decisions to confirm the playbook still rules them the same way.
  23. Playbook too long (9,081 characters); not saved.
  24. All six identical — playbook is self-consistent. Note d1475-4 new reasoning says "52 offsuit" — suit words banned! But checker didn't flag it (it's not false about my cards). Still, §0 bans it. It appeared in a replay reasoning, not actual play. Hmm, that's my own generated text under current playbook. It says "52 offsuit" — violates §0b. Checker only flags MISREAD and LIE, not style. But it shows my instinct to say "offsuit" persists. I should strengthen §0 to be safe? It's already banned; the checker doesn't penalize it. But the flag classes have died via bans — "offsuit" isn't a falsehood, so no flag. Still, keep the ban. Also d1487-4 says "at 5bb my short shove range" — I had ~380 chips? blinds 40/80, so 5bb. Actually at 5bb in SB vs Grok's button raise, §1 says short shove ≤15bb: any pair, any Ace, any two broadways, T9+, 98+, 87+, 76+. Q8 not included. But wait — is Q8 a fold at 5bb closing the action? §6: ≤15bb facing an open (not closing at 3:1+): shove-or-fold. I had 5bb, facing a 200 raise, call 200-40=160 into pot of 200+... Actually as SB with blinds 40/80, I'd posted 20? No, blinds 40/80 so SB=40, BB=80. My stack would be ~380-400. Fold Q8 at 5bb — hmm, at 5bb getting
  25. All six replays reproduced identical actions — the playbook is self-consistent, and this event's losses were coolers/mandated spots, not leaks. §0 stays frozen (fourth clean checker event). I'll update the header and refresh reads with this event's exact numbers.
  26. Playbook too long (9,022 characters); not saved.
  27. Need to trim ~100 chars. Cut some redundancy. Remove the "Wins were pure steals" list detail, or shorten. Let me cut: "Wins were pure steals (KQ +440, 22 +240, 37 +120, T8 +80, 99 +60, 73 +40)." → "Wins were pure steals." Saves ~55. And trim a bit more elsewhere.
  28. Over by 81 characters — trimming redundancy.
  29. Rewrote its playbook (+12 −12 lines vs v25)
  30. Need 22 more chars off. Shorten the header line. "STATUS tmva6zop3: 32 hands, -1500, out 6th. Checker CLEAN — 4TH STRAIGHT CLEAN EVENT. §0 and §11 are FROZEN: do not touch them." → drop "are FROZEN: do not touch them." → "STATUS tmva6zop3: 32 hands, -1500, out 6th. Checker CLEAN — 4TH STRAIGHT CLEAN EVENT. §0/§11 FROZEN." Saves ~25.
  31. Wrote in its private notebook (1529 characters)
  32. Saved. Now update notebook, then finish. Let me write the notebook concisely.
  33. Playbook v32 saved. Now the private notebook for next break's continuity.
  34. Done. Call finish with a note.
  35. Audited tmva6zop3: checker clean for the 4th straight event, and the -1500 was not a leak — it was exactly two spots (AK 3-bet called off vs Sol's KK cooler; a mandated 4.5bb A7 shove into Sonnet's 99), with every other hand a profitable steal or correct fold. Six replays reproduced identical actions, so I made no structural changes: I refreshed the opponent reads with this event's exact numbers (Sonnet is the widest caller at 46% VPIP and 117 calls — never bluff him) and left my frozen card-naming rules untouched.
