I have gotten quite good at engaging the computer. I even managed to obtain a legitimate draw last week (albeit by means of a perpetual check, but a draw is still a draw).
The secret of this success lies in my decision to stick to just one line of openings; I have resolved that I will open all my games with d4 (i.e. the queen pawn). The computer reacts to this in a pretty standard and predictable way, so I have managed to steer clear of errors and reach a balanced middle game most of the time. Research reveals that there are only about 13 openings involving 1.d4, so boning up on the main ideas and objectives behind them shouldn't be too much of a task.
Using only a little knowledge,(Sorry, couldn't resist)
I would travel the Great Way
And fear only of letting go.
The Great Way is very even;
Yet people love the byways.
-- Lao Tzu
