Anti-computer strategies generally use long term strategy as the basis for defeating computer. In other words the human player is said to create a grand strategy that is adaptable depending on the computer's strategy. The Local strategy that I am about to present is a short term one. Here is the game for review against the computer with search depth 7(the highest available on this particular version):
Note the use of strategy duality. By being aggressive solely with the queen we trick the computer into proceeding down search paths involving the queen and white aggression. By pulling back this tricks the computer into attempting to attack along the right while trapping the leftmost rook, bishop, and knight. However we quickly eliminate the pawn trap with another pawn and now use our three pieces in the end game. Keeping our king close to the pawns allows us to utilize all our "soldiers" in the pursuing end game as was planned. Now we can play rather carelessly as we out number him. Note that the trading is crucial as most computer strategies and many human strategies involve saving the rooks for the end in order to trap the king. As long as we eliminate one when the opportunity arises as we did, and aggressively trade pieces to eliminate most of the computer's flank, either right or left but remember to keep the opposite closed for your pieces. Here is a graph showing the computer's estimation of who has the advantage. Note the significant jump between the early and last moves. Also note how the computer is convinced of its own ability to win at Nh3, this is part of the strategy, as the Pseudo random erratic moves that we make greatly "confuse" the search algorithm.
