[Critical] 16... Bb6 (me): W/L/D 100.0/0.0/0.0 -> 0.0/15.6/84.4, eval 4.60 -> -0.66, expected score 1.00 -> 0.42 (-57.8 pts)

• Impact: me=negative (-57.8 pts), opp=positive (+57.8 pts)
• Best: Ra8 (Stockfish+Lc0) | Played: Bb6 | Opportunity cost: 11.98 pawns worse
• Engines: Stockfish=5.20 pawns worse, Lc0=18.77 pawns worse, confidence=Medium
• Evidence: SF PV Ra8 Ba6 Bc8 Rd1 Bd6 Qf5 | Lc0 PV Ra8
• Cause: 16... Bb6 was inferior to Ra8; it created a large practical drop compared with safer continuations. Evidence: expected score 1.00 -> 0.42 (-57.8 pts), Stockfish 5.20 pawns worse, Lc0 18.77 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 also had 1 capture(s), increasing tactical volatility.
• 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.
