Answers.Body: <p>I ran the game through Stockfish at 5 minutes per move. Here are a few key moves.</p>
  
  <pre><code>15...Nxd4?? +- 
  +3.34 / +0.00
  ( 15...Re8 16.Bf4 Nxd4 17.Bg3 Qg5 18.Bf4 Qg1+ 19.Qxg1 hxg1=Q+ 20.Rxg1 = )
  </code></pre>
  
  <p>What we see here is that with this move, Black goes from an even game to being down a piece. Black maintains parity with Stockfish's suggested move (in parentheses above...)</p>
  
  <p>The issue with the move is that exposes all of Black's sins:</p>
  
  <ol>
  <li>The Knight is trapped.</li>
  <li>The Black Queen is unprotected and doesn't coordinate with any other piece.</li>
  <li>Black's King is flapping in the breeze.</li>
  </ol>
  
  <p>Black in on the edge of death now. Your <code>f5</code> is the best response to a bad situation. It was far better than my choices - they all lost instantly to some variation of <code>Bg5</code>. For example:</p>
  
  <pre><code>[FEN "r4k1r/ppp4p/3p1p2/3B4/3n3q/2N5/PPP4p/R1B2Q1K w - - 0 16"]
  
  1.Ne4 c6?? 2.Bg5
  </code></pre>
  
  <p>And you can see that White's going to smash f6 and the Black King like a freight train.  Instead, if Black takes the <code>e</code> file with the Rook, White can't develop an attack on the weak <code>f</code> pawn.</p>
  
  <p>Here's Stockfish's suggested continuation wherein Black maintains parity:</p>
  
  <pre><code>[StartFlipped "0"]
  [title "After 15. Nc3"]
  [fen "r4k1r/ppp4p/2np1p2/3B4/3P3q/2N5/PPP4p/R1B2Q1K b - - 1 15"]
  
  1...Re8 2.Bf4 Nxd4 3.Bg3 Qg5 4.Bf4 Qg1+ 5.Qxg1 hxg1=Q+ 6.Rxg1
  </code></pre>
  
  <hr>
  
  <p>Of course, I goofed up and lost most of the Stockfish analysis. It is fiddly indeed.</p>
  
  <p>Now, on White's 17th, White is basking in the mess Black made for himself with the premature capture on <code>d4</code>.    Stockfish recommends:</p>
  
  <pre>
  <code>
  [title "After 17.Bg5??"]
  [StartFlipped "0"]
  [fen "r4k1r/ppp4p/3p4/3B1pB1/3nN2q/8/PPP4p/R4Q1K b - - 1 17"]
  
  1... Qg4 2.Bh6+ Ke7 3.Bg5+ Kf8
  </code>
  </pre>
  
  <p>and Black escapes with a three-fold repetition because White's about to lose the Knight on <code>e4</code> for a pawn. It's protecting the Bishop on <code>g5</code> and can't move.</p>
  
  <p>A nice game, full of chances.</p>

Answers.Text: That part is not that interesting; it is, according to DB, won position, although tricky to win OTB. I meant the part of the game after the queens are exchanged, that is where there are still pawns (and plenty of them on black's side!) on the board - after move 23. It seemed like I was able to collect the pawns way too easily with white...

Answers.Body: <p>As a king's gambit player myself, I just want to note a few things about the very first moves:</p>
  
  <p>Combining Nc6 and exf4 is actually playable though very much a sideline. Reacting with 4.Bc4 however, is a mistake and I think the reasoning behind this is instructive:</p>
  
  <p>4.Bc4 allows black to play 4…g5 without allowing white's standard responses. Nc6 takes e5 away from the Nf3, just like d6 would, so the Kieseritzky isn't possible anymore for white. But after 3…d6 4…g5 would be a well known mistake, because 1.e4 e5 2.f4 exf4 3.Nf3 d6 4.Bc4 g5 5.h4 g4 allows 6.Ng5 with a tremendous attacking position. Nc6 on the other hand doesn't just control e5, it also allows black to defend f7 with tempo in this variation, so 1.e4 e5 2.f4 exf4 3.Nf3 Nc6 4.Bc4 g5 5.h4 g4 6.Ng5 Ne5! and black is in time to rebuff the white attack 7.Bb3 h6 8.d4 hxg5 9.dxe5 and black is much better.</p>
  
  <p>Better, and quite logical, would be 4.d4, when a quick d5 is in the air, possibly followed by Qd4. </p>
  
  <p>About the endgame: A tablebase win in 46 moves might sound quite long and complicated, but it probably just means that black has to give his rook for a bishop in a couple of moves, transposing to the well known NBK vs K, which is often still 30+ moves until mate, but rather straightforward (if you know it). </p>

Answers.Text: +1 - Thanks for the comments about KG - it is one of my favourite blitz game openings. As for the endgame, actually, it takes more than a couple (accurate!) moves to force black to give the rook up - over 20. Anyway, K+B+N vs K is far from trivial with seconds on the clock, hence black should have played on. And hey, sometimes even GMs fail to mate in that endgame...

  I ran the game through Stockfish at 5 minutes per move. Here are a few key moves.
  15...Nxd4?? +- 
  +3.34 / +0.00
  ( 15...Re8 16.Bf4 Nxd4 17.Bg3 Qg5 18.Bf4 Qg1+ 19.Qxg1 hxg1=Q+ 20.Rxg1 = )
  
  What we see here is that with this move, Black goes from an even game to being down a piece. Black maintains parity with Stockfish's suggested move (in parentheses above...)
  The issue with the move is that exposes all of Black's sins:
  
  The Knight is trapped.
  The Black Queen is unprotected and doesn't coordinate with any other piece.
  Black's King is flapping in the breeze.
  
  Black in on the edge of death now. Your f5 is the best response to a bad situation. It was far better than my choices - they all lost instantly to some variation of Bg5. For example:
  [FEN "r4k1r/ppp4p/3p1p2/3B4/3n3q/2N5/PPP4p/R1B2Q1K w - - 0 16"]
  
  1.Ne4 c6?? 2.Bg5
  
  And you can see that White's going to smash f6 and the Black King like a freight train.  Instead, if Black takes the e file with the Rook, White can't develop an attack on the weak f pawn.
  Here's Stockfish's suggested continuation wherein Black maintains parity:
  [StartFlipped "0"]
  [title "After 15. Nc3"]
  [fen "r4k1r/ppp4p/2np1p2/3B4/3P3q/2N5/PPP4p/R1B2Q1K b - - 1 15"]
  
  1...Re8 2.Bf4 Nxd4 3.Bg3 Qg5 4.Bf4 Qg1+ 5.Qxg1 hxg1=Q+ 6.Rxg1
  
  
  Of course, I goofed up and lost most of the Stockfish analysis. It is fiddly indeed.
  Now, on White's 17th, White is basking in the mess Black made for himself with the premature capture on d4.    Stockfish recommends:
  
  
  [title "After 17.Bg5??"]
  [StartFlipped "0"]
  [fen "r4k1r/ppp4p/3p4/3B1pB1/3nN2q/8/PPP4p/R4Q1K b - - 1 17"]
  
  1... Qg4 2.Bh6+ Ke7 3.Bg5+ Kf8
  
  
  and Black escapes with a three-fold repetition because White's about to lose the Knight on e4 for a pawn. It's protecting the Bishop on g5 and can't move.
  A nice game, full of chances.

  As a king's gambit player myself, I just want to note a few things about the very first moves:
  
  Combining Nc6 and exf4 is actually playable though very much a sideline. Reacting with 4.Bc4 however, is a mistake and I think the reasoning behind this is instructive:
  
  4.Bc4 allows black to play 4…g5 without allowing white's standard responses. Nc6 takes e5 away from the Nf3, just like d6 would, so the Kieseritzky isn't possible anymore for white. But after 3…d6 4…g5 would be a well known mistake, because 1.e4 e5 2.f4 exf4 3.Nf3 d6 4.Bc4 g5 5.h4 g4 allows 6.Ng5 with a tremendous attacking position. Nc6 on the other hand doesn't just control e5, it also allows black to defend f7 with tempo in this variation, so 1.e4 e5 2.f4 exf4 3.Nf3 Nc6 4.Bc4 g5 5.h4 g4 6.Ng5 Ne5! and black is in time to rebuff the white attack 7.Bb3 h6 8.d4 hxg5 9.dxe5 and black is much better.
  
  Better, and quite logical, would be 4.d4, when a quick d5 is in the air, possibly followed by Qd4.
  
  About the endgame: A tablebase win in 46 moves might sound quite long and complicated, but it probably just means that black has to give his rook for a bishop in a couple of moves, transposing to the well known NBK vs K, which is often still 30+ moves until mate, but rather straightforward (if you know it).
