  <p>Deliberately playing bad moves in the hope that your opponent will blunder is called "hope chess". If you want to improve then you have to try and stop doing that because it won't work against good players.</p>

Answers.Text: I see nothing wrong with Nxe4 considering the variation that the OP has given looks really good for black. Qa5+ probably wins a pawn by force but white seems to get some compensation for that. I'd rather just get 2 bishops, a pawn center and lead in development.

  Short answer no.<br>
  If it were good more people would be playing it.
  It is more an example of a slash and burn tactical player that should fall short if black plays carefully.</p>
  
  <p>If you play really weak players there is a good chance they will make mistakes and fold like a broken chair. </p>
  
  <p>Against a better player White gets the material back but black gains tempi chasing the White Queen and will have the two bishops plus a slightly better center.</p>
  
  <p>Minor positional advantage to black should make up for castling by hand instead of the normal way.</p>
  
  <p>Will a super deep computer analysis change the assessment?  Who knows? Who cares?  The game is played by people not computers and anything can happen depending on many factors. </p>

Comments.Text: I fail to see how white gets any positional advantage and would prefer black in this position. If anything white's position looks borderline losing unless there is some engine line to capitalize on black's king. Just my first thoughts at looking at the position because I've never seen it before.

  Good for who?
  Short answer no.

  It is more an example of a slash and burn tactical player that should fall short if black plays carefully.
  
  If you play really weak players there is a good chance they will make mistakes and fold like a broken chair.
  
  Against a better player White gets the material back but black gains tempi chasing the White Queen and will have the two bishops plus a slightly better center.
  
  Minor positional advantage to black should make up for castling by hand instead of the normal way.
  
  Will a super deep computer analysis change the assessment? Who knows? Who cares? The game is played by people not computers and anything can happen depending on many factors.
