Answers.Body: <p>Your analysis is pretty much to the point. I am not a 1. d4 or Slav player, but the opening looks fine to me. </p>
  
  <p>Basically you liked the (sham) sacrifice starting with 14 e4 so much that you ignored the fact that black is not forced to take (15... fxe6). This whole line basically weakened your d4 pawn which is difficult to defend afterwards.</p>
  
  <p>As it is quite obvious around move 20 that you are going to lose the d4 pawn sooner or later, you should have come up with some ideas for counterplay, perhaps along the e-file, and also I would have kept more pieces on the board increasing your chances. If you are down material you need to play actively. Your position at move 26 is the very opposite of that.</p>
  
  <ol start="27">
  <li>a5 would allow you to avoid getting the doubled pawn. Black cannot try to win material with 27 ... Nc2 because of the passed pawn.</li>
  </ol>
  
  <p>At some point around move 33 you achieved an equal position which you should not lose. It is not easy to play because black's king is more active and your knight on the rim, but if you can activate your king and get the knight to more active squares (perhaps via c4 or b3 since you got stuck shuffling the knight between b7-a5 later) there should be no danger. Having the remote a pawn vs the c pawn should slightly favor you.</p>

Comments.Text: +1 for the work you already put into the analysis. You imo already found the main missed opportunities for improvement in the middlegame. Still, at first glance, you seem to have equalized again around move 34, so you should probably have a little closer look at the following moves that do finally lose you the game.

  Your analysis is pretty much to the point. I am not a 1. d4 or Slav player, but the opening looks fine to me.
  
  Basically you liked the (sham) sacrifice starting with 14 e4 so much that you ignored the fact that black is not forced to take (15... fxe6). This whole line basically weakened your d4 pawn which is difficult to defend afterwards.
  
  As it is quite obvious around move 20 that you are going to lose the d4 pawn sooner or later, you should have come up with some ideas for counterplay, perhaps along the e-file, and also I would have kept more pieces on the board increasing your chances. If you are down material you need to play actively. Your position at move 26 is the very opposite of that.
  
  27. a5 would allow you to avoid getting the doubled pawn. Black cannot try to win material with 27 ... Nc2 because of the passed pawn.
  
  At some point around move 33 you achieved an equal position which you should not lose. It is not easy to play because black's king is more active and your knight on the rim, but if you can activate your king and get the knight to more active squares (perhaps via c4 or b3 since you got stuck shuffling the knight between b7-a5 later) there should be no danger.
