Answers.Text: See what you are saying is right but white will not take time to change the position of bishop so anyhow black will need to play the move of Rh7. So I think I should go with that move.

  <p>I would argue that Rh7 is the best move in this position.

  The knight on h5 is pinned to a rook, and faced with the potential threat of g4. To unpin this knight, Black should play Rh7, so that the knight is free to go to f6 (where it will protect the rook).
