Answers.Body: <p>It's partially who the opponent is, and partially how much better the opponent is.</p>
  
  <p>I've gone from ~1750 to almost 1900 in the last year (approximate as ECF grades - 142-158 to those who understand ECF). In that time I've played a lot of players who are appreciably better than me. <strong>But not massively better</strong>; most have been 1850-2100. That meant I could still give them a challenge, even if I was stretched to hold them for the whole game. In fact a major moment in that improvement was I when I had to play my first ~2050+ player in that period, I was sort of doing OK but a little worse, and then I suddenly realised he a had let me off the hook. This 2050 player had made a mistake! I can not explain quite how much confidence that gave me, and I went on to draw the game, and in fact missed a win along the way. The whole episode set me up for the season, and the game is below.</p>
  
  <p>So that's the first point, good enough so that you see and understand their plans, and that they stretch you, but also not so good that it's wham, bang, thank you mam. The second point is that a lot of the players I have played in this period have been kind enough to go through the games with me. This helped me understand their expectations, and often showed me ideas that I had not even considered. This was coupled with has the 2100+ player at my (small) club helping me, The later in particular clarified my impressions of my opponents plans, helped me identify some of my tactical weaknesses and showed me what both of us had missed over the board.</p>
  
  <p>So for you I suspect 2000+ is a bit rich. But look for players who are</p>
  
  <ul>
  <li>Around 100-300 higher than you </li>

Answers.Body: <p>I believe it all comes down to the learning process. Having the possibility to play against players that are stronger than you is a strong asset that you should use most of the time.</p>
  
  <p>Let me give you an example. You have 1400ELO. If you play against 2k+ you'll get destroyed every game. After that when you play against 1.6k and you are close to their level and learn the small differences of why you get beat. The other thing you do learn is how much of a difference there is between 1.6k and 2k+. It shows you how much you could learn and at what pace.</p>
  
  <p>The important thing in this is seeing the differences and what you have to learn, just like at school/university at the first class you see the whole curriculum for the year. It sets your mind at peace and harmony and prepares it for the task at hand.</p>

Then you can take that new knowledge back into your games against lower rated opposition.</p>

  It's partially who the opponent is, and partially how much better the opponent is.
  I've gone from ~1750 to almost 1900 in the last year (approximate as ECF grades - 142-158 to those who understand ECF). In that time I've played a lot of players who are appreciably better than me. But not massively better; most have been 1850-2100. That meant I could still give them a challenge, even if I was stretched to hold them for the whole game. In fact a major moment in that improvement was I when I had to play my first ~2050+ player in that period, I was sort of doing OK but a little worse, and then I suddenly realised he a had let me off the hook. This 2050 player had made a mistake! I can not explain quite how much confidence that gave me, and I went on to draw the game, and in fact missed a win along the way. The whole episode set me up for the season, and the game is below.
  So that's the first point, good enough so that you see and understand their plans, and that they stretch you, but also not so good that it's wham, bang, thank you mam. The second point is that a lot of the players I have played in this period have been kind enough to go through the games with me.

  I believe it all comes down to the learning process. Having the possibility to play against players that are stronger than you is a strong asset that you should use most of the time.
  
  Let me give you an example. You have 1400ELO. If you play against 2k+ you'll get destroyed every game. After that when you play against 1.6k and you are close to their level and learn the small differences of why you get beat. The other thing you do learn is how much of a difference there is between 1.6k and 2k+. It shows you how much you could learn and at what pace.
  
  The important thing in this is seeing the differences and what you have to learn, just like at school/university at the first class you see the whole curriculum for the year. It sets your mind at peace and harmony and prepares it for the task at hand.
  
  Hope this helps.

  You learn from defeats when your mistakes are punished and made plain for you to see. You learn nothing from victories where your mistakes go unpunished and your ego is given an unwarranted boost.
  
  No coach, by the way, advises that you play against opposition which is 600 points higher rated. That said you can still learn a lot from games against them. Try, for instance, to play lines which give you problems when you face them to see how the stronger player handles them. Then you can take that new knowledge back into your games against lower rated opposition.

  To expose poor play and mistakes. To punish. To push the player to play better moves and learn new ideas.
  
  All the obvious stuff.
  
  Once you divorce yourself from your love of your rating, it's pretty obvious.
  
  Edit: FYI - 200 point difference is sufficient. You should not play players consistently rated 600+ points above you. 200 is a good threshold. The same goes for reverse - don't play players frequently rated 200+ points below you. If you have the choice, always "play up".

  I am not sure how one coach's opinion makes it that all chess coaches are like that.
  
  The best advice that I would give you as a coach would be "Play as many Open tournaments as possible" because in the Open category, you are likely to meet equal, weaker, stronger players and at the end of the tournament, you would have a lot of points to improve upon. Play with me on Chess dot com and I will be happy to give you a post-mortem of the game at the end of it.
