[Critical] 14. Qb5 (me): W/L/D 18.8/0.0/81.2 -> 0.0/87.2/12.8, eval 0.69 -> -1.31, expected score 0.59 -> 0.06 (-53.0 pts)

• Impact: me=negative (-53.0 pts), opp=positive (+53.0 pts)
• Best: Bxc5 (Stockfish+Lc0) | Played: Qb5 | Opportunity cost: 1.85 pawns worse
• Engines: Stockfish=1.88 pawns worse, Lc0=1.82 pawns worse, confidence=High
• Evidence: SF PV Bxc5 Qxd3 Bxd3 Rfc8 Ba6 Rc7 | Lc0 PV Bxc5
• Cause: 14. Qb5 was inferior to Bxc5; it weakened coordination and handed over initiative. Evidence: expected score 0.59 -> 0.06 (-53.0 pts), Stockfish 1.88 pawns worse, Lc0 1.82 pawns worse.
• What you likely thought: The move looked playable, but a deeper safety/coordination check would have flagged the downside.
• What you missed on the board: You likely missed piece coordination and loose-piece tension after the move. After your move, the opponent also had 1 capture(s), increasing tactical volatility.
• How to decide better next time: 1) Check king safety. 2) Check loose pieces. 3) Prefer moves that improve both activity and stability.
• Practice habit: Use a fixed three-step blunder check before committing.
• Lesson: Solid coordination beats speculative activity.

[Critical] 40. gxh3 (me): W/L/D 100.0/0.0/0.0 -> 0.3/0.8/98.9, eval M+14 -> -0.10, expected score 1.00 -> 0.50 (-50.2 pts)

• Impact: me=negative (-50.2 pts), opp=positive (+50.2 pts)
• Best: Rxh4 (Stockfish+Lc0) | Played: gxh3 | Opportunity cost: 542.06 pawns worse
• Engines: Stockfish=1000.06 pawns worse, Lc0=84.05 pawns worse, confidence=Medium
• Evidence: SF PV Rxh4 hxg2 Nf3+ Kf6 Kxg2 Kf5 | Lc0 PV Rxh4
• Cause: 40. gxh3 was inferior to Rxh4; it won material short-term but handed over tactical momentum. Evidence: expected score 1.00 -> 0.50 (-50.2 pts), Stockfish 1000.06 pawns worse, Lc0 84.05 pawns worse.
• What you likely thought: Humans are pulled toward obvious material gains and can stop calculating once a capture looks winning. The trap is ending the calculation before testing the opponent's forcing reply.
• What you missed on the board: The key missed cue is recapture/tempo risk after the grab: loose pieces, exposed king, and forcing counterplay. You captured a pawn, so recapture tempo needed deeper verification. After your move, the opponent had 2 checking idea(s), which is a forcing-warning signal.
• How to decide better next time: 1) After any tempting capture, calculate the opponent's forcing reply first. 2) Re-check king safety and piece safety two plies deep. 3) If unclear, choose the safer improving move.
• Practice habit: Treat every 'free' pawn or piece as suspicious until the tactical sequence is proven safe.
• Lesson: If a gain looks free, verify the punishment line before taking it.

[Critical] 41. h4+ (me): W/L/D 0.5/0.5/99.0 -> 0.0/100.0/0.0, eval 0.00 -> -3.17, expected score 0.50 -> 0.00 (-50.0 pts)

• Impact: me=negative (-50.0 pts), opp=positive (+50.0 pts)
• Best: Nf3+ (Stockfish+Lc0) | Played: h4+ | Opportunity cost: 1.96 pawns worse
• Engines: Stockfish=3.09 pawns worse, Lc0=0.83 pawns worse, confidence=Medium
• Evidence: SF PV Nf3+ Kf6 Nh4 Re7 f3 Rg7+ | Lc0 PV Nf3+
• Cause: 41. h4+ was inferior to Nf3+; it stepped into a forcing sequence and reduced your practical choices. Evidence: expected score 0.50 -> 0.00 (-50.0 pts), Stockfish 3.09 pawns worse, Lc0 0.83 pawns worse.
• What you likely thought: A move can look active but still hand initiative away if the opponent gets forcing tempo moves. Humans underestimate this when they don't compare initiative after each candidate.
• What you missed on the board: You needed to count forcing replies available to the opponent after your move. After your move, the opponent also had 1 capture(s), increasing tactical volatility.
• How to decide better next time: 1) For each candidate, count opponent forcing moves. 2) Prefer candidates that reduce forcing replies. 3) Keep king and loose pieces stable.
• Practice habit: Judge candidate quality by how many forcing replies you concede.
• Lesson: Good moves reduce opponent forcing options, not just improve your own piece.

[Critical] 42. f3 (me): W/L/D 100.0/0.0/0.0 -> 0.0/100.0/0.0, eval M+20 -> -5.58, expected score 1.00 -> 0.00 (-100.0 pts)

• Impact: me=negative (-100.0 pts), opp=positive (+100.0 pts)
• Best: Nf3+ (Stockfish+Lc0) | Played: f3 | Opportunity cost: 532.10 pawns worse
• Engines: Stockfish=1005.38 pawns worse, Lc0=58.81 pawns worse, confidence=Medium
• Evidence: SF PV Nf3+ Kf5 Kxh4 Ke4 Ng5+ Kd3 | Lc0 PV Nf3+
• Cause: 42. f3 was inferior to Nf3+; it created a large practical drop compared with safer continuations. Evidence: expected score 1.00 -> 0.00 (-100.0 pts), Stockfish 1005.38 pawns worse, Lc0 58.81 pawns worse.
• What you likely thought: Humans under time pressure often pick the first workable move instead of comparing two serious candidates. That shortcut is costly in sharp middlegames.
• What you missed on the board: The missed cue was decision quality, not only tactics: candidate comparison and safety checks were incomplete. After your move, the opponent had 2 checking idea(s), which is a forcing-warning signal.
• How to decide better next time: 1) Pick two serious candidates. 2) Run a brief CCT scan for both sides on each. 3) Choose the line with fewer immediate tactical liabilities.
• Practice habit: Never play the first acceptable move in sharp positions; compare at least two candidates.
• Lesson: Candidate comparison prevents large practical blunders.

[Critical] 46. Nd6 (me): W/L/D 100.0/0.0/0.0 -> 0.0/100.0/0.0, eval M+18 -> -4.40, expected score 1.00 -> 0.00 (-100.0 pts)

• Impact: me=negative (-100.0 pts), opp=positive (+100.0 pts)
• Best: fxe4 (Stockfish+Lc0) | Played: Nd6 | Opportunity cost: 538.45 pawns worse
• Engines: Stockfish=1004.81 pawns worse, Lc0=72.09 pawns worse, confidence=Medium
• Evidence: SF PV fxe4 Kxf7 a4 Kf6 Kh4 Ke5 | Lc0 PV fxe4
• Cause: 46. Nd6 was inferior to fxe4; it created a large practical drop compared with safer continuations. Evidence: expected score 1.00 -> 0.00 (-100.0 pts), Stockfish 1004.81 pawns worse, Lc0 72.09 pawns worse.
