 For example, a novice player faced with a situation like position 1 in the diagram on the right, in which some boxes can be captured, may take all the boxes in the chain, resulting in position 2.But, with their last move, they have to open the next, larger chain, and the novice loses the game.A more "experienced" player faced with position 1 will instead play the "double-cross strategy", taking all but 2 of the boxes in the chain and leaving position 3.
