You had your plan and have decided to stick with it. That is why you missed the winning lines, because you didn't give other moves a chance. Have you evaluated properly that you get winning initiative after `18.Bxd5` you would have found the winning lines in no time and would play the move in a second. Unfortunately, there is no advice, other than I already gave you, for improving in the evaluation of the position. Better luck next time...

Answers.Body: <p>You missed at least TWO tactical chances.</p>
  
  <p>On move 26, you made a very common mistake; you failed to realize that your king was smothered in your "back rank." If you had realized this, you would have moved your rook on d1 along the first rank, instead of "chasing" the bishop, and allowing what turned out be a deadly pin.</p>
  
  <p>Many players play h3, or in this case, a3, as soon as possible, because of all the potential combinations that can arise from this pattern, which appears time and again. (You should have played a3 on move 25 before moving the rook to d1). I would guess that a lot of your "one move" faux pas arises from not knowing patterns like these. Learn them, and a lot of mistakes will go away.</p>
  
  <p>You can see how your rook on d1 was "hobbled" by the insecurity of the king's position. The safety of the king is the first priority in chess. </p>
  
  <p>As pointed out by Always Learning New Stuff, you also missed an opportunity on move 19 to play Bxd5, capturing the d pawn, and "forking" the knight and f pawn (the latter leads to mate). When Black defends the f pawn, you can capture the knight with B, thereby avoiding the "skewer" of your queen and rook by the Black bishop.</p>
  
  <p>But the "back rank" problem is the more common one, which is why I answered it first.</p>

Comments.Text: @MikhailTal: *It's the Re1+.* That is the consequence of psychological collapse you suffered from, after losing your advantage. The position has changed from "won for White" into "advantage for White". When you squander such an advantage, never "continue" to play. Take a break to calm down when you realize you lost the advantage and reassess the position. This is crucial to remember -> reassess only when calmed down. It seems to me like you kept playing "on inertia" for an attack while position required few "consolidating moves" from you in order to continue with your initiative...

  The answer is simple and cruel -> evaluation of the position. Unfortunately, being inactive for 10+ years, I suffer from the same problem so I know what I am talking about.
  
  You will not find a winning move, nor winning lines, unless you evaluate that they are there in the position. That is why you miss those moves -> you didn't even consider that such possibilities exist in the position.
  
  Can you answer me these questions:
  
  * How did you evaluate the position in the game, after your opponent played `17...Nd5` ?
  * Did you even consider `18.Bxd5 cxd5 19.Nxd5!` since `19...Qxd5?? 20.Qf6 Nd3+! 21.Rxd3 Qe5 22.Re3! Qxf6 23.Rxe8#` mates? Did you see this line, and if you did why did you dismissed it?
  * Why didn't you play `19.Bxd5!` with the same mating tactic as above, instead of weak `19.Nf3` ?
  
  What I am trying to say is that you didn't evaluate the position properly. Maybe you thought it was advantage for White ( `+0.80` or something similar... ) while I believe it was won for White ( `+1.60` at least ).
  
  **I strongly believe that you would have found these lines on your own if you thought you had a won position.**
  
  Solving tactical puzzles can fix this problem to some extent, but you really need to learn how to evaluate the position properly and this comes with experience. Reading books about typical middlegame positions helps as well, so does strong knowledge of endgames. These will help you in the beginning.
  
  I advise you to start with tactical puzzles, and then move towards typical middlegame positions.
