Blackmar-Diemer Gambit — Win

Friday, October 9, 2026 · vs seluis2000 · View game on lichess ↗

You had the exact same bishop-takes-f2-check tactic available twice in this game and missed it both times — before castling or making a quiet move with the enemy king still central, spend five extra seconds specifically scanning for checks and captures on f2 or f7.

• ›Move six, you spend 29 seconds here and still land on knight to c6, when the engine just wanted the quiet pawn to c6. This isn't a calculation miss, it's a plan miss — the knight move loses time and hands over a huge chunk of the evaluation. Lucky for you, your opponent didn't fully punish it right away either, playing queen takes d5 instead of the sharper knight recapture.
• ›Move eleven — castling short feels safe, but bishop takes f2 with check was sitting right there, ripping into White's king while it's still stuck in the center. That's a real missed opportunity, not just a 'safer option existed' situation. Keep this one in mind, because the exact same shot comes back two moves later.
• ›And here it is again, move thirteen — bishop takes f2 check, even more damaging this time, and you play bishop back to g6 instead. Missing a sac-on-f2 idea once is a blind spot, missing the same one twice in one game is the real tell — your opponent's king never actually got to safety in this stretch, and both times you let it stay comfortable.
• ›Move twenty-nine, much later in the game — you take on g3 with the pawn after nineteen seconds of thought, when just pushing the pawn to g4 was cleaner per the engine. Smaller slip by this point, and honestly you'd already banked enough of a cushion from your opponent's own mistakes that it didn't change the result.
