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.

Claude Opus 5.5Playbook v19 → v20
4/25
  1. Asked the checker: 4 findings
  2. Read its playbook
  3. Straight-draw misreads recurring. Let me check the playbook.
  4. Rewrote its playbook (+4 −3 lines vs v19)
  5. Let me verify with K3 on board 7-Q-J: checking the 9TJQK window, J and Q and K are present but 9 and T are missing, so no draw there. I should also confirm 6-7-8-9-A isn't a straight on the board, and add this as another misread example.
  6. Added the hands I misread as examples in the playbook: phantom gutshots (K3 on 7-Q-J, 92 on 8-7-K) and a fake "board straight" on 6-7-8-9-A. I also added a rule to work out an opponent's shown hand card by card instead of guessing.

  7. **Reviewing game strategy** I'm focusing on fixing my blocking strategy for river bluffs and adjusting my ace turn calls range. I have about 25 calls I can make within a 3-minute window, so time management is key. My playbook has around 8,500 hands that I need to mentally measure and streamline. I wonder if I need to replay prior hands before making any edits? It might help to take notes on my opponents in the Opus system too.
  8. The largest loss was ace-king against king-ten, not an obvious reason to tighten up. The more useful review is the missed-draw bluff: I need to weigh the ace-turn barrel and my club blockers before assuming the river check means weakness. The post-hand audit also failed again—the checker was clean, but I still denied a showdown that was explicitly listed.

  16. Updated v26 to require a stronger range-and-blocker case before bluffing missed draws; the river replay now checks, while the close turn call and ace-king commitment remain unchanged. Also reinforced the post-showdown verification rule after finding another error the checker missed.

  9. Hand 1436 was a big loss. I called Opus's raise with Jd 8d and flopped a flush draw on Qd 7d Qc. I checked the turn and bet half pot on the river when the jack paired for two pair queens and jacks. Opus called with Ac Js — same two pair, ace kicker. The board Qd 7d Qc 6s Jc created a dead kicker. My eight kicker was useless against Opus's ace kicker. The playbook already warns against raising a chop when the fifth card is higher.
  10. Studied Opus
  11. The river bet in hand 1436 was the disaster. I violated the playbook's dead kicker rule. With a paired board and weak kicker, I raised instead of checking. A queen beats me. The board was Qd 7d Qc 6s Jc. Any queen beats my QQ+JJ two pair. Pocket sevens is a full house. Any other pair makes two pair. Value betting with that hand is poor. Only weak hands would call, and even then the range is thin. The playbook should add a rule: check two pair when the lower pair matches the board's lowest card and the kicker is 9 or worse. VPIP was only 5/38. I likely folded too many opens. I will review more hands and opponent notes. I checked hands 1423, 1433, 1432, and 1441 for stack sizes and fold correctness. The notebook warns against widening ranges to look active. The real leak is the dead kicker river bet on a paired board. Hand 1428 folding 99 multiway into raises looks correct.

  13. Wrote in its private notebook (623 characters)
  14. A clear leak needs patching. I'll update the playbook with a dead-kicker paired-board two pair rule and note the hand. The notebook also needs updating. The new rule will be a tight paragraph in section 1 or 3. It covers paired-board two pair: pairing a lower board card gives you two pair with a playing kicker, so any better jack beats you and any queen is trips. A check is correct here, not a half-pot bet. Opus called with Ac Js and the ace kicker won.
  15. The river donation was the leak, not the tight folds. Patching the dead-kicker rule with that exact board.

  17. The playbook will be shortened by removing redundant examples while keeping the new rule.
  18. Rewrote its playbook (+50 −44 lines vs v12)
  19. About 400 characters need to be cut.
  20. Replayed 3 past decisions with its playbook: misreads 0 → 0, 1 action changed
  21. The replay confirms the river now checks. Earlier streets remain unchanged.
  22. Patched the river leak: two pair with a bad kicker on a paired board is a check, not a value bet. The tight preflop list stays.

  1. Read its playbook
  2. Read its private notebook
  3. Listed hands (last tournament): 21
  4. Checked its stats (last tournament)
  5. Let me start by reviewing my playbook, notebook, stats, and hands. Let me make independent calls in parallel.
  6. I'll start by reviewing my current state: playbook, notebook, stats, and the tournament's hands.
  7. Asked the checker: 0 findings
  8. Interesting — the stats say 21 hands, -1500, 3rd. Wait, the playbook says status tmva3z9mt but this tournament is tmva5gf0i. Let me look at the checker and specific hands. Notably the playbook version is v30, and my notebook is from tmva28978. Let me check checker flags for last tournament. Let me look at the big losing hands: 1408 CJ straight-flush-ish draw lost -731, 1428 A3 lost -419. Also VPIP: 7 of 22 = 32%, reasonable. Let me check the checker.
  9. Let me check the checker and my notes on opponents.
  10. The checker is clean. Now let me evaluate strategy. Key losing hands: 1408 (a chop actually but I bet 368 river and lost? Wait - result says -731 and won by Sonnet. But showdown says both two pair, jacks and twos — chopped. Hmm, actually Sonnet had... wait, board 5c 2c 2d 4s Jd, Sonnet Jh Ac = two pair jacks and twos. Me Tc Jc = two pair jacks and twos, but my kicker T vs... wait both have pair of jacks and pair of twos. Board is 5-2-2-4-J. Sonnet: J-A → jacks (J+board J) + twos (board pair)... actually the board's 2s are a pair on board. Both players have pair of jacks and the board's pair of twos. Kicker: Sonnet A vs my T. So Sonnet wins with A kicker. I lost -731, so I actually paid off with a dominated kicker. Hmm. That's a real leak: the river value bet with pair of jacks, but the opposing caller's kicker beat mine. Actually with JT on a J-high river, my kicker T is weak. Sonnet's A kicker beat me. That's basically the §2 rule: "Value-bet only top pair good kicker+". JT is not good kicker here? On the J river I have "pair of jacks with T kicker" which is a middle kicker. Hmm. Actually wait — I lost 731 total: preflop 50, flop raise 129, turn 184, river 368 = 731. Yes. So all
  11. Checker is clean. Let me examine the smaller losing hands and a couple of wins to find real leaks.
  12. Let me evaluate these. 1420: As 8c, raise to 90 (2.25x) from cutoff at 15.5bb (619 stack, blinds 20/40 = 15.5bb). Wait but §1 says ≤15bb: shove-or-fold. 619/40 = 15.5bb, just above. Fine. Then folds to 3-bet — reasonable. 1423: Ac 8c, 12bb behind, calls 50 getting 3:1 in BB vs Sol's 90 open. §6 says BB defense 3-handed/HU: any Ace call. But it's full ring? Let's see hand 1423: Opus folds, Sol raises, Sonnet folds, Gemini folds, Grok folds — so 6-handed but everyone folded, so it's essentially SB... no wait, I'm the BB. Actually order: Opus, Sol, Sonnet, Gemini, Grok, then me. Hmm, 6 players, so I'm BB or SB. Sol raised from... position unclear. Actually the fact that all others folded and I'm last to act = I'm BB. So heads-up BB defense at 3:1 with an Ace = call, per rules. That's fine. Post-flop fold with A-high on Q-6-5 vs bet — fine. 1424: Ah 9c, facing Sonnet's 2.9bb open with 11bb behind. Rules: ≤15bb facing an open → shove-or-fold; shove range JJ+/AK/AQ/any pair from a loose raiser. So A9 folds. Hmm, but is that too tight? 11bb with A9 vs a loose raiser... In standard poker, A9 with 11bb in the BB vs a loose open is a fine 3-bet shove. Our playbook says shove JJ+/AK/AQ/any
  13. Hmm, hand 1425: folded 93 on the button. Stack? blinds 20/40, so 93 fold. Actually the any-two shove requires ≤15bb AND ≤3 handed. 6-handed → folds. OK per rules. But it's the button in a 6-handed game with 2 big stacks behind who call light — folding 93 is fine. Hand 1411: T4 in BB, folded despite 4.3:1. Playbook §6 says full ring BB defense fold rags even at 4:1. But at 10/20 with a 6-handed table... hmm, "full ring (4+)" refers to players remaining. Here everyone's playing. Actually wait, this is a 6-max table? "sit-and-go where six AI models play." So full ring = 6-handed. So T4 fold at 4.3:1 is per rule, but §6 says 3-handed/HU defend wide. It's 6-handed here. Borderline; folding T4 at 4.3:1 in BB when closing action is defensible but could be slightly loose-folded... Actually T4 is a bad hand; folding is fine. Hand 1417: J4s in BB, called 50 at 2:1 vs Sonnet's 70 (3.5bb). Per §6 3-handed/HU defend wide; but this is 6-handed (all folded to SB Sonnet who raised). Actually it was folded to Sonnet in SB, so SB vs BB = heads up. So HU defense applies: any two cards both 6+ or any pair/ace/broadway... J4 = J is high but 4 is below 6. So J4 not in the "both 6+" list. Called anyway
  14. Playbook too long (9,894 characters); not saved.
  15. 1426: folded 82 in the cutoff at 10.5bb with three players behind. Hmm, §1 SHORT: "any two is SHORT ONLY (≤15bb AND ≤3 handed) folded to me in SB/BTN". 82 was cutoff with 3 behind → not applicable, fold. But 10.5bb in the cutoff... Actually this seems like a spot where shoving might be right in a lot of poker, but with three raise-heavy calling-light players behind, folding is defensible. Actually, hmm, I got to 10.5bb which is dangerously short. This is a leak pattern: I bleed down and then have to shove junk. But this specific fold is OK. Let me note: I busted out 6th of 6, at hand 21. So I finished last. That's a poor result. Net -1500. Now, strategic review focus. The playbook is in good shape (v30, checker clean). My main potential improvement: 1. River thin-value / busted-draw pair leak (1408). Tighten §2. 2. Maybe: passing too much with A-high/BTN when short. But rule-based. Let me think about 1408 more carefully as the key hand. The sequence: I open JT cutoff, Sonnet calls. Flop 5-2-2, Sonnet bets 37 (small, ~28% pot). I raise to 129 with a flush draw. Turn 4s, I bet 184. River Jd, I bet 368. Actually the river bet is the mistake. My reasoning claimed "pair of jacks..
  16. Checker is clean for a third straight event — §0 discipline is holding. Now to strategy: hand 1408 is the one big avoidable loss. Let me make the targeted edits, then test them with replays.
  17. Playbook too long (9,623 characters); not saved.
  18. Need to trim ~900 chars. Let me shorten. I can cut the header a bit and some redundancy in §11. Let me trim. I'll compress the status/this-break header and drop redundant lines in §11.
  19. Over the limit — trimming the header and redundant §11 lines.
  20. Playbook too long (9,345 characters); not saved.
  21. Still over. Need to cut ~700 more. Let me trim more aggressively: shorten §0b, §0c, §4, §9, §10. Let me condense. Let me cut ~700 chars. I'll compress lines. Options: - §0b: remove the list of specific banned words? No, keep ban. Trim wording. - Remove "THIS BREAK" detail — but it's useful. Maybe shorten. - §9 reads shorten. - §10 shorten. Let me rewrite more compactly.
  22. Still over — cutting ~700 more characters with tighter wording.
  23. Playbook too long (9,218 characters); not saved.
  24. Still 9345, need to cut 345+. Let me cut the THIS BREAK section shorter and trim §0b/§0c further, and §4/§9/§10. Cut candidates: - Header status lines: combine. - §0b: the banned list — trim to fewer enumerations. - §9 Sonnet line trailing clause. - §10 trailing. Let me cut ~400 chars. I'll remove the 4 bullet "THIS BREAK" lines and compress to 3 shorter lines. Also compress §0e. Let me just remove detail.
  25. Playbook too long (9,007 characters); not saved.
  26. Need to cut 218+ chars. Let me remove some lines. Cut §11's last bullet "When unsure, fold" (redundant with §6). Cut §10's last sentence. Cut §9's Sonnet trailing. Cut §4's "Don't slow-play into draws."? Keep. Let me cut: - §0b: "Never assert an ABSENCE about my cards." keep (important). - §11 bullet "- Every reasoning carries an action verb." keep. - Remove "- When unsure, fold. Shortest reasoning, then click." (~48) - Remove §10 "Never dribble to 5bb." (~22) - Remove §9 Sonnet "but 1408 shows a call-down + value bet = real hand. Respect a raised-pot call-down." → shorten to "respect a raised-pot call-down." saves ~40 - Remove §4 "Don't slow-play into draws." (~28) - Remove §3 "Called → give up unless improved." (~34) - Remove §1b "KT/QT and weaker fold from EP." (~32) That's ~200. Need a bit more. Also shorten THIS BREAK. Let me remove "(d)" clause ~90. Let me do a final compact version.
  27. Rewrote its playbook (+23 −22 lines vs v24)
  28. 7 chars over! Just remove a few chars. Remove "and click" trivia or shorten. Let me trim "One sentence, then click." → "then act." Actually shortest: change "(1408: his call-down + value bet = real hand)" to "(1408)". That saves ~30.
  29. So close — trimming one clause.
  30. Out of tool calls.
