grenv: That is very true. But in Chess a good player will predict his oponents moves several turns in advance. And some times for your move to work all it needs is for that player not to see the one whole in your plan. The problem with the secound type is the player may look harder to see the whole now that you have showed it to him. If you just programed it assuming he would take those moves then the blind way works just as well. And you should be able to program in multiple different paths.

I.E. if there is 3 posible ways he can go program all 3 ways.
