Body: <p>I'm not sure whether this qualifies as a trap, but I sometimes do this tactic. My opponent pins my knight on f3 against my queen, but by sacrificing my bishop to f7, I can move the knight with check then use the queen to take the bishop.</p>
  <p>For instance:</p>
  <pre><code>[FEN &quot;&quot;]  
  1. e4 e5 2. Bc4 Nc6 3. f4 exf4 { C33 King's Gambit Accepted: Bishop's Gambit, Maurian Defense } 4. Nf3 Bc5 5. d4 Bb6 6. O-O d6 7. Bxf4 Bg4 8. Bxf7+ Kxf7 9.Ng5+ Ke8 10.Qxg4
  </code></pre>
  <p>Is there a name for this?</p>
  <p>(Side note: Stockfish rates this move as a blunder, decreasing evaluation from 1.7 to 0.3, even though I gain a pawn, prevent black castling, and leave their position more exposed. I'm curious why.).</p>

Title: Does this tactic (Bxf7+ KxB, Ng5+...QxB) have a name?
ThreadText: # Does this tactic (Bxf7+ KxB, Ng5+...QxB) have a name?
  
  (Asked by: username_0 on 2022-05-12)
  
  I'm not sure whether this qualifies as a trap, but I sometimes do this tactic. My opponent pins my knight on f3 against my queen, but by sacrificing my bishop to f7, I can move the knight with check then use the queen to take the bishop.
  For instance:
  [FEN ""]  
  1. e4 e5 2. Bc4 Nc6 3. f4 exf4 { C33 King's Gambit Accepted: Bishop's Gambit, Maurian Defense } 4. Nf3 Bc5 5. d4 Bb6 6. O-O d6 7. Bxf4 Bg4 8. Bxf7+ Kxf7 9.Ng5+ Ke8 10.Qxg4
  
  Is there a name for this?
  (Side note: Stockfish rates this move as a blunder, decreasing evaluation from 1.7 to 0.3, even though I gain a pawn, prevent black castling, and leave their position more exposed. I'm curious why.).

  Bxf7+ is an attraction of the king to the f7 square, after which Ng5+ is a discovered attack of the undefended bishop on g4. Technically, one could call Ng5+ a double attack/fork as well since you're simultaneously attacking the king and the bishop.
  
  The official name would be an attraction followed by a discovered attack.
  
  As always, loose pieces drop off! Gotta calculate all checks, captures, and threats!
