Most basic themes involve something along these lines:
1.  Make a closed position to buy time.  Computers have a very tough time when
there is no immediate pawn or piece to snack on.  They sometimes move in a very
aimless manner in closed positions.
2.  Castle to the opposite side as your opponent and then start a pawn storm.
3.  Move all your pieces over to the opponent's kingside for an all-out attack.
This does not work as well as it used to, because programs are now a lot smarter
about king safety.
4.  Stonewall attack used to be pretty good.  Not so much any more.  Some
programs detect it now.
