Query: Playing the opponent

This is a very good book for an intermediate player who wants to know how to play the opponent and the situation rather than playing only what is on the board.He sets the situation and the opponent for each sample game and lets you in on how he modifies his game as he plays it.Tim Holland was a former world champion and backgammon pro. (Defined by bridge pro Skid Simon as someone who plays for higher stakes than he could afford if he were a losing player.)
