Chess is interesting. My main strategy is to maximize enemy casualties while minimizing my own. I wait until the last possible moment to sacrifice a piece, and even then only if I can gain a more important piece than the one I lost (importance based, of course, on the current board and the pieces there).

I rarely ever forecast moves ahead. Not consciously, at least. I can anticipate enemy movements, though, and I usually act based on that.

My strategy is very situational. I have never given time to study "real" chess strategy and I will probably never waste my time doing so. There has to be freedom of form- it is not interesting to me if the movements I make are just automatic reactions to stimulations, though the concept itself is interesting.
