Answers.Text: I've been looking through a lot of the sample problems of this type and it's led me to believe that they likely (?) design the game state for these puzzles such that a single move is unlikely to change the balance of the game. For example, if white is behind in points, they either can't possibly capture anything that would change the  advantage (e.g. they're 2 points behind and can only capture pawns) or, if they did, they'd likely lose as many points when black played again (e.g. they take a rook but then black can take their queen).

Body: <p>My second grader is preparing for the UIL Chess Puzzle Solving competition in January and I've been reviewing the question types to help him and his club prepare.

Comments.Text: I think #4 is a case of needing four options (A, B, C, D) and there are only three obvious ones (either x > y, x = y, or x < y) so you gotta come up with something for option D, even if it's silly.

Comments.Text: Sure. I'm willing to accept that as an explanation and had considered it already. That said, *because* who's to move *can* factor into the overall advantage of the game, it seems like the puzzles would have to be carefully designed to avoid situations where the next move could drastically flip the balance of the game (without being a horrible move).

Title: Does whose turn is next impact material advantage?

  It perhaps depends on how strict your definitions are. Consider the following position:
  
  ```
  [fen "rnb1kbnr/pp1ppppp/8/q1p5/Q1P5/8/PP1PPPPP/RNB1KBNR w KQkq - 2 3"]
  
  ```
  
  Although, technically, material is even for the moment, the side to move is about to realize a large material advantage. It would be folly to analyze the position without this being the primary consideration. As an even more extreme example, if White played Qxd7+ here, White would then be up a pawn and therefore technically have a material advantage, but Black *must* retake, so that "advantage" is illusory.
  
  I am guessing that the tests will not contain such a question in this context, however, as it would be rather unfair to the students.
