As white i figure i have such a large advantage over my opponant (cough cough) that i prefer to play the guico piano, developing pieces and taking control of the center. Then daring black to beat my from there. I know the first 3 moves of this devastating opening. Look out for it when you play me as black.
When i play black, my mindset is that i have already lost, so i throw everything at white in an attempt to rush him or make him panic and then it becomes a dog fight where either side can win (or loose the game). And as black i will take those odds. I'm liable to do something like the centre gambit just to shock white and have him scrambling for his text books.
After mastering the first 3 moves of the Guico, i expanded my repotoire and have tried to play a few games where i open with the kings gambit. I liked the idea of trading off a pawn for time and space, and against some newbies they couldnt decide whether to take the offered pawn or not (believing it to be too good to be true and thus a trap) and that simply broke them mentally for the rest of the game. Again, i have memorised the first 3 moves of this opening.
I remember also working through Birds opening but i honestly cant remember how that one went. I read a simple paragraph about the GM Bird (maybe even the Chessmaster description) and thought he sounded good so i dug up Birds opening.
