Doerdich: But, obviously, you cannot "test" a position and move back after seeing what might be revealed ... the revelation only comes after you have committed tot he move. Likewise, if you are still wqatching the game and your opponet is "testing" positions, you do not see what they have moved (if, indeed you an) until they have committed to the move.
