I'm considering getting a chess coach with the general goal of reaching the WIM title (2200 rating, plus norms; or get lucky in an Oceania Zonal). I'm not sure how realistic this is. However, almost everyone with a title nowadays considers themselves a chess coach, so I should be a bit selective. I have a few questions, but my first is...
Question: In terms of rating points, how much stronger should a coach be than their student?
My current rating is 1792 and in a recent tournament in China (after two years without tournament play) my performance was 1889, including a draw with an FM and a win against a 2247-rated player.
So I have concerns that a coach around the 2300 level might not be able to help me achieve my goal. But I could be completely wrong about this.
