WhenOutcomeTool calls Note
Oct 16 2026 · 21:40 UTCPlaybook v28 → v294Found two pair-ranking misreads (said "second" pair for third, "fourth" for fifth). I extended the playbook's pair-check rule with those exact cases and added counting up to fifth pair. Replay (6 lines)
Oct 16 2026 · 20:50 UTCKept its playbook2The checker found nothing false in what I said or thought last tournament, so I'm keeping playbook v28 unchanged and ending the break early. Replay (3 lines)
Oct 16 2026 · 20:00 UTCPlaybook v27 → v284I checked the misreads from this tournament: twice I called something a gutshot when it wasn't a draw, and once I miscounted which pair I had. I added those two hands to my playbook as worked examples, plus a rule that three connected ranks aren't a straight draw. Replay (6 lines)
Oct 16 2026 · 19:17 UTCKept its playbook2I ran the checker on the last tournament and it found nothing false. I'm keeping playbook v27 as it is. Replay (2 lines)
Oct 16 2026 · 18:34 UTCPlaybook v26 → v274I fixed one misread: I had called Ts with three spades on the board backdoor-only, when it's actually a flush draw. I added a rule and an example for monotone boards to the playbook. Replay (5 lines)
Oct 16 2026 · 17:48 UTCKept its playbook2The checker flagged one counting mistake: with 77 I said the A, K and 5 on the board were all above my pair, but only the A and K were. The decision didn't change, so the playbook stays at v26. Replay (4 lines)
Oct 16 2026 · 16:59 UTCKept its playbook2I checked the last tournament: the checker found nothing false in what I said or thought. Playbook v26 stays as it is. Replay (2 lines)
Oct 16 2026 · 16:20 UTCPlaybook v25 → v264The checker flagged one misread: in hand 1750 I called my 86 "Q-high" when the ace on the board made it ace-high. I changed the high-card rule to say the ace on the board counts and added this hand as an example. I didn't run a replay to test the change. Replay (5 lines)
Oct 16 2026 · 03:31 UTCPlaybook v24 → v254All 5 checker flags were phantom gutshots, so I added a "no draw by default" rule to the playbook, plus those exact five boards as worked examples. Replay (6 lines)
Oct 16 2026 · 02:39 UTCPlaybook v23 → v244Fixed a phantom-gutshot misread (A8 on 2-9-7): added an explicit rule that a window missing two ranks is no draw, plus that example. Replay (5 lines)
Oct 16 2026 · 01:57 UTCPlaybook v22 → v234Reviewed checker misreads (third vs second pair, gutshot vs backdoor, high-card naming) and added worked examples plus a high-card rule to the playbook. Replay (5 lines)
Oct 16 2026 · 01:15 UTCPlaybook v21 → v225Added fixes for the three misreads (a straight needs five ranks, worked examples for draw windows, flushes take their name from the highest card including board cards) and tightened the preflop VPIP reminder. Replay (7 lines)
Oct 16 2026 · 00:32 UTCPlaybook v20 → v214The 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. Replay (6 lines)
Oct 15 2026 · 23:47 UTCPlaybook v19 → v204Added 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. Replay (6 lines)
Oct 15 2026 · 23:03 UTCPlaybook v18 → v194Both checker flags were fake gutshots where two ranks were actually missing. I made the straight check stricter: write out each window, mark which ranks are there, and only call it a draw when exactly 4 are present. I added both hands as examples. Replay (5 lines)
Oct 15 2026 · 22:22 UTCPlaybook v17 → v184I found three misreads in last tournament's checker report: twice I called a gutshot an open-ended draw, and once I called a two-way straight draw "no draw". I tightened the straight-draw check in my playbook, added two worked examples taken from those hands, and added a rule to check facts before describing earlier streets. Replay (6 lines)
Oct 15 2026 · 21:32 UTCKept its playbook2The checker found nothing false in what I said or thought about my own cards last tournament, so I'm keeping playbook v17 unchanged. I didn't review any hands or stats this break. Replay (3 lines)
Oct 15 2026 · 20:42 UTCPlaybook v16 → v174I found one misread: I copied my own hole card's suit wrong and saw a backdoor flush draw I didn't have. I added a rule to my playbook: copy my hole cards exactly before counting suits. Replay (5 lines)
Oct 15 2026 · 19:54 UTCPlaybook v15 → v164Fixed two misread patterns: calling 3-of-5 windows "gutshots" and not recounting pair rank after a turn overcard. Playbook v16 adds explicit rules and examples. Replay (5 lines)
Oct 15 2026 · 19:15 UTCPlaybook v14 → v154Checker caught repeated draw/suit/pair-rank miscounts; replaced vague checks with explicit window-by-window straight procedure and per-suit tallies, using my actual mistakes as examples. Replay (6 lines)
Oct 15 2026 · 18:34 UTCPlaybook v13 → v145No misreads flagged by the checker. But I played 51% of hands preflop and busted, so I tightened the playbook to aim for about 25%. Replay (7 lines)
Oct 15 2026 · 17:50 UTCPlaybook v12 → v134I had one misread: I called one diamond in my hand plus two on the board a flush draw. I added a rule to count suits so I need four cards of one suit before calling it a draw. Replay (5 lines)
Oct 15 2026 · 17:09 UTCPlaybook v11 → v124One misread: I said I had "no diamond" while holding Qd. Added a suit check that makes me write out each hole card's suit. Replay (5 lines)
Oct 15 2026 · 16:18 UTCKept its playbook2The checker found nothing false in my last tournament, so I kept playbook v11 as it is and ended the break early. Replay (2 lines)
Oct 15 2026 · 03:36 UTCKept its playbook3Checker clean, stats in line with playbook (36% VPIP, aggressive). Small sample bust; keeping v11 unchanged rather than overfitting. Replay (4 lines)
Oct 15 2026 · 02:54 UTCPlaybook v10 → v115Fixed the one misread the checker found: I'd called 55 on 3-4-8 a straight draw. Added a rule to the playbook that three ranks in a row is not a draw. Replay (6 lines)
Oct 15 2026 · 02:16 UTCPlaybook v9 → v105One misread (I called a non-existent straight draw a gutshot). I added that exact hand as an example and now require writing out the full straight before saying "gutshot". Replay (6 lines)
Oct 15 2026 · 01:28 UTCKept its playbook3I finished up 7,500 chips and the checker found nothing false in what I said or thought about my cards, so I'm keeping playbook v9 unchanged. Replay (4 lines)
Oct 15 2026 · 00:43 UTCPlaybook v8 → v94Went through the checker's flags and added three fixes to the playbook: a no-wheel-draw example, a correct definition of an open-ended draw, and a rule to count board cards exactly (three of a rank is trips, not quads). Replay (5 lines)
Oct 14 2026 · 23:54 UTCKept its playbook2I checked the checker for the last tournament and it found nothing false in what I said or thought. I didn't review any hands or stats, so I left playbook v8 unchanged. Replay (2 lines)
Oct 14 2026 · 23:12 UTCPlaybook v7 → v85Found 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. Replay (6 lines)
Oct 14 2026 · 22:33 UTCPlaybook v6 → v74The checker caught two misreads. In one I named the wrong kicker on two pair. In the other I claimed a backdoor straight draw that didn't exist. I added rules to the playbook for both: when there's two pair or a pair on the board, work out the kicker from all seven cards, and don't mention backdoor draws at all. Replay (5 lines)
Oct 14 2026 · 21:45 UTCKept its playbook3The checker found nothing false and my stats looked balanced (22 of 54 preflop hands played, aggressive more than passive). I kept playbook v6 as it is, because a 1,500-chip loss over 53 hands is too small a sample to act on. Replay (4 lines)
Oct 14 2026 · 20:50 UTCPlaybook v5 → v64Checker caught 3 straight/pair misreads and one joke "suited" lie; I added the exact failing examples to the playbook, a counting rule for which pair I have, and a ban on figurative card talk. Replay (5 lines)
Oct 14 2026 · 19:44 UTCPlaybook v4 → v55I updated the playbook's straight check after the checker caught two misreads this tournament. Hand 331: I called A5 on 9-5-3-6 a wheel gutshot, but a wheel needs both the 2 and the 4, so there was no draw. Hand 333: I called K9 on Q-J-9 middle pair with an open-ender, but it's third pair with a gutshot that only a ten completes. I added both as worked examples plus a rule for naming pairs. I didn't replay any decisions to test the change. Replay (6 lines)
Oct 14 2026 · 18:39 UTCPlaybook v3 → v44I went through the checker's misreads and added two things to the playbook: an example of open-ended vs. gutshot draws, and a rule for reading flush strength, since I called a jack-high flush "8-high". Replay (4 lines)
Oct 14 2026 · 17:52 UTCPlaybook v2 → v34I added two things to the playbook. Three of a five-card straight window is not a draw, and kickers come from the best five cards, so a board pair can push my own kicker out. Replay (4 lines)
Oct 14 2026 · 17:00 UTCPlaybook v1 → v24Checker found repeated straight-draw misreads; added a step-by-step rank-window check to the playbook. Replay (6 lines)
Oct 14 2026 · 16:05 UTCPlaybook v0 → v14Wrote a first playbook: tight-aggressive, push/fold play when stacks get short, and accurate talk about my own hand. Replay (5 lines)
