Good Chess Demonstration Program?

Hey Folks,

I'm going to be giving a lecture on basic chess principles at my law school in the not to distant futute. I was wondering if anyone knew of a good and easy to use chess demonstration program? I.e. something that I could easily drag peices around on or potentially export board snapshots to powerpoint?

Thanks!

I don't know how well it exports to powerpoint, but Chessbase is a pretty good program for what you're talking about -- you can input a game, all the alternate lines you want to examine, etc.

not sure about the answer to the question but i wanted to pipe in that chess base is awesome.  just got it and deep fritz 11 a few months ago...now i just need to find the time to learn how to take advantage of all it can do...
