• If you have pawns or rooks, check what pieces they can reach first - they're pretty limited in most puzzles, so they're quick to figure out. Also, bear in mind that chess pawns can skip over blocks in the second row
  
  
  
• Otherwise go over the pieces on the board one by one. Look at them, and try to trace back the path a particular piece - say, a knight or a bishop - would have to take in order to reach them. Start from the end - where the target piece sits - and go back to the start. That way you can quickly figure out which of your pieces can't capture a particular targetpiece (e.g because there are blocks in the way), and from which tile you need to send them into what direction. Rinse and repeat for every piece on the board - if multiple pieces could take a target, you'll have to play around a bit to figure out the correct order.
  It's a bit of a handful if you have knights, admittedly, but that's the kind of game it is. Get those grey cells working :D!
  
  
  
• I usually trace with a finger or my eyes, but you could theoretically take a screenshot and use paint to draw lines, or draw a board on a sheet of papwer with a pencil and eraser. Probably too much effort for most, but hey, some people do better with visual aids.
  
  
• Gotta be patient.
