I think the Lopez/Kasparov method (hence forth the LK method) of organizing openings makes the most sense for what I want to do. Basically enter the name of the variation into the game header, and add games to the particular lines that I play, versus entering a game and adding tons of variations at each possible branch. It makes finding the deviations so much easier. Regardless it is still a ton of work. There are mainlines and critical sub-variations for every opening. Fortunately I have worked very hard on finding out which openings suited my particular style of play and worked to streamline the possible responses of my opponents. One also has to keep in mind the possibilities of transpositions from one system to the next. I had already pretty much established those lines prior to beginning the Circles exercises. (I think the only thing I haven’t done is researched in depth what I want to play versus against the English as Black. The symmetrical variation has served me well in the past, but I know there are some sharper lines that offer more counter play for Black.)
So anyway I started reading through several of the Chessbase USA "T-Note" archives to get a better grasp on more of the hidden features Chessbase has to offer, also to avoid shooting myself in the foot when I’m further down the road.
I have found in the past that the case with most software is the user manages to utilize only a small fraction of the software’s capabilities. Of course I’m guilty of doing this too, but I have also noticed that if I take the time to read through the tutorials, and various message boards it will make my life simpler in the long run plus I get a better grasp on the product overall.
Of course entering all of these variations into Chessbase is just a piece of the puzzle, only a small step in the journey. The real work begins once I start drilling these systems and it will give me a reference point for all of my future games.
Wish me luck.
