Answers.Text: That Bxg3 line can make things more difficult for black. Though the king has to run to d2, the center is closed and White can make use of an open f-file after 3...fxe4, or large central space gain after 3... dxe4 4. Bh5+ folllowed by an eventual c4.

Answers.Text: With black's two pawns being passers, the game is unclear.  The main problem is that black can't castle after Bh5+.

  The correct answer was <code>fxe4 fxe4 Bxh5+</code>.
  Why can the knight not just move to <code>f6</code> and be safe there?</p>
  
  <p><code>fxe4 Nf6 exd5 fxd5</code> is in my opinion more preferable for black.</p>

Title: Why doesn't 1.fxe4 Nf6 work for black in this puzzle?

  (Asked by: username_0 on 2017-07-28)
  
  I was solving puzzles and I failed this one.
  The correct answer was `fxe4 fxe4 Bxh5+`.
  Why can the username_3 not just move to `f6` and be safe there?
  
  `fxe4 Nf6 exd5 fxd5` is in my opinion more preferable for black.

  Because after `Nf6, e5` is a double attack on the `d6` bishop and the `f6` username_3.
  
  The puzzle aside, given that black's dropping the piece anyway, may as well go for something practical, like `Nxg3, hxg3, Bxg3+...` and take 2 pawns for the piece, with some positional compensation as the king will be misplaced, but objectively white should of course be easily winning.
