title: How are value assigned to moves in minimax or other strategy in Chess?
body: <p>I am trying to understand how values are assigned to different moves in AI chess strategy. For example user has 3 options moves pawn, queen or knight, then for each move the opponent has 3 moves. Those moves have values: move rook + 3, move Queen +2, move Pawn -3 and so on. </p>
  
  <p>So, what represent these numbers, the number of moves opponent has or the item opponent can beat(if beat a rook is +2 if beat a pawn is 0)?</p>
  
  <p>Sorry if my question is confusing.</p>
