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. Found three hand-reading slips: twice I called a third pair "middle" or "second" pair, and once I got my two pair wrong. I rewrote the pair check to ban the word "middle" and to count the board ranks above my pair, and added a two-pair check.

  7. **Evaluating errors in strategy** I need to carefully inspect the overall results from my strategy, especially focusing on the big winning and short losing positions to find any errors. It’s essential to understand where I may have gone wrong or where my method could improve. I’m curious about what I might uncover from this inspection and how it can refine my approach in the future. Let's get into the details and see what I find!
  8. The final jacks shove looks standard; the queens showdown is not a reason to tighten it. I’m focusing instead on calls with players still behind and on tournament-pressure claims that need actual payout information.

  11. Read its playbook
  12. The replay preserved the sensible jacks shove, but it still invoked a “payout bubble” without establishing the payouts. I’m tightening that instruction and requiring explicit main- and side-pot arithmetic before rejecting a cheap reshove call.
  13. Rewrote its playbook (+18 −22 lines vs v8)
  14. **Considering document revisions** I need to think about how to revise this document without losing important details. Shortening it to 700 words is my goal, but it also has to convey the strongest priorities. I want to ensure that the essence of the original content stays intact while being more concise. It might be helpful to use my old notebook as a reference to identify key points that I want to preserve in the new version. Let's get to work on this!

  17. Updated to v9 with explicit main- and side-pot call calculations, a known-payout requirement for bubble arguments, and more scrutiny of large out-of-position three-bets. Kept the short-stack value aggression: the final jacks shove was sound despite running into queens.

18/25
  1. Read its playbook
  2. Asked the checker: 2 findings
  3. Listed hands (last tournament): 36
  4. Checked its stats (last tournament)
  5. Let me start by looking at my playbook, stats, and hands.
  6. The playbook I got is v9 already? It says v9 at top but the note says "Your playbook is v8." Whatever — this is the current playbook text. Net -1500, busted. Let me look at the big losses: 559 (-1000), 566 (-777), 570 (-1122), 548 (-324), 558 (-200). And wins: 541 (+1530), 560 (+353), 569 (+160). Let me read the key hands.
  7. Let's analyze these. Hand 559: I raised J7s in SB to 200 at 40/80 (2.5x) — fine, deep. Flop middle pair + flush draw, bet 3/4 pot, called. Turn Kd — I bet 500 into ~1000. Board 5c7sQcKd. I have middle pair + flush draw. River Ad, I check. Opus checks with Q9 — I lost 1000. Hmm. Actually with middle pair + flush draw on turn, betting is aggressive but the K is a bad card. But actually I lost 1000 on a hand where I had decent equity. It was a value bet that ran into top pair. Reasonable, though maybe turn bet too big. Actually 1000 chips lost is a lot at 40/80 — that's 12.5bb. Wait stack? This was hand 25, blinds 40/80. My river check was correct. This is more variance. Though: middle pair + flush draw, the turn K is overcard; Opus called flop, likely has a Q. Betting turn into a caller with middle pair is questionable. But equity-wise I have ~14 outs. Actually 500 was half pot which is fine. Hand 566: shove A2o at 12bb from CO. Standard. Lost to Gemini's A9. Fine, no leak. Hand 570: shove ATs at 7bb BTN. Standard. Lost to Sol's AJ. Fine. Hand 548: A9o in BB, flop Q73, I called 1/4-pot with ace-high, then rivers an ace making two pair aces and queens, but Sol had ATo — kicker. I

  9. These all look reasonable and disciplined. The playbook is working. Net -1500 is variance from all-in shoves. Notable: 541 — "flopped a set of sevens, only 9-9 or an unlikely straight beats me" — actually T8? No. On 2-7-9 rainbow, straights need... fine. Also earlier I thought "top set" then was flagged; engine says middle set. In the hand I wrote "set of sevens," no error there. Fine. Interesting: 560, I won with nines but the reasoning called it "third pair (nines)" — 9-A-K-8... nines is third pair (K, A above; 8 below). Actually ranks: A, K, 9, 8, 3. My pair of 9s is third-highest pair. Correct. So the main conclusion: my play is fine; losses are variance. The playbook is already very detailed and good. What can I improve? One thing: the vocabulary/precision section is huge and I still misread (KTs). The language test exists but I still made the KTs error. Root cause: I habitually write "KTs" shorthand for KTo. Fix: never use the s/o suffix from memory without checking; or just don't use suit notation in my reasoning at all. Second misread: "top set" when it's middle set. Minor, no action impact. Also I should consider: my VPIP 14/37 = 38% preflop which is above the ~22-32

  12. d548-10 the playbook still says raise half pot. My playbook §3 says check thin value... but I rivered two pair (aces and queens). Is that a value bet? Board Qc7d3sQdAs. My two pair = aces and queens, kicker 9. Any A-x with kicker > 9 beats me, but Sol raised preflop from... Sol raised to 90 (2.25x) preflop. Sol could have AK, AQ, AJ, AT. Those all beat me. But Sol also could have KK, JJ, TT, 88, etc. Actually the bet got called by AT (better). Hmm but also Sol would call with worse — e.g., KK, JJ, TT? Maybe not, they'd check/call a small bet? Actually KK/JJ/TT might call a half pot bet on that river. Hmm. Actually my two pair (aces and queens) isn't "second pair" — it's top-ish. Per §3, "board-paired two pair when a higher board card is live — CHECK." Here the board is Q-Q and I have an ace. The A on the river means aces live. The rule is about board-paired two pair. Here it's aces up which is legitimately strong-ish but the ace means A-x dominates. Hmm. The replay kept the same action. So the playbook agrees with bet half pot. Maybe it's fine — Sol may call with worse. It's marginal. Not a clear leak. Actually the key mistake in 548 was calling the flop with A9 high and then...
  13. Rewrote its playbook (+34 −33 lines vs v8)
  14. Sol raises a lot preflop (141 bets/raises preflop of 477) — actually that's across all streets. Sol is the tight-solid raiser who showed strong hands. Let me now update the playbook. I'll keep the core and make targeted improvements: 1. Add explicit "never use s/o suit suffixes in thought or speech unless verified — write 'offsuit/suited' explicitly." 2. Set naming. 3. One-line talk, no volleys. 4. Keep everything else. Actually the playbook says v9 in the header but the tournament note says v8. The tool returned the current playbook — that's what I play with. Let me rewrite as v10. Let me also add a small note: with sticky loose callers (Sonnet/Opus), shoving is less effective as a steal — prefer shoving real value and be cautious with marginal aces at 10-15bb. Hmm, but 566 (A2o 12bb) and 570 (ATs 7bb) were both standard. Actually A2o shove from CO at 12bb — from the playbook §7b: "An ACE (even A2o) at ≥3:1 ... is a CALL." And §2 says "any Ace" in shove range. So A2o shove is by the book. Fine. Let me write the playbook. Keep under 1200 words. I'll tighten and add the fixes.

  17. Replayed 3 past decisions with its playbook: misreads 0 → 0, 0 actions changed
  18. I have calls left. Let me do a couple more replays to validate the new playbook on the tricky spots — e.g., d559-7 (turn bet) and d548-5 (flop call with ace-high). Also d566-1, d570-2 to confirm. Actually let me just replay the river/ace spots to confirm the new rule kicks in. d548-10 already kept same. Let me test d558-7 and d543. Actually I'm near the end. Let me do one more replay batch on a few decisions to confirm the playbook is coherent, then finish.
  19. Consistent. Playbook is coherent. Done. Let me finish.
  20. Reviewed the whole event: my late shoves (A2o 12bb, ATs 7bb) and the AA-up river were variance, not leaks, but I found three real fixables — I called Ks Th "KTs" and 77 a "top set" (shorthand set-naming errors), and I broke my own one-line talk rule with a 3-line volley. Playbook v10 kills the s/o shorthand, names sets from the top board rank, adds a weak-kicker-ace river check, and bans talk volleys.
