How to catch what you play as white up to your black repertoire

My last tournament I was beating players of a certain level as black consistently, where as with white I'd end up with a draw or being slightly worse. How do you keep your repertoires even with each other? Do you just pick a single line in an opening as white, and learn it, rather than trying to tackle the whole opening?

Generally your White repertoire can be broader than your Black.  You don't have to know your White openings inside out since second best moves are generally not fatal as White.  If you pick a single opening line, it is very easy for a Black player to prepare for you.  Tartakower once said "White has his initiative to defend."  What this means is that you have to work and think hard as White to maintain your edge.  If you don't work at giving Black problems to solve, then your game tends to go down hill.  Work hard to understand the underlying ideas in  White openings, but don't worry about memorizing.  There is no reason White has to engage in long forced tactical variations that have to be memorized.  For instance if Black plays the Sicilian,  you  do not have to play the open Sicilian; but if you do chose to play the open Sicilian pick a Be2 line.  If you are counterpuncher by nature and not comfortable taking the initiative, try studying Korchnoi's games as White.

It looks like you have put a lot of work in your black repertoire, so maybe your handling of the black pieces is just better at the moment.

Or maybe the positions you get out of your white games don't suit you ? Difficult to say without analyzing the games !?

@Phelon: Without more details, it’s difficult to make even an educated guess, but I have some ideas, which you might want to look into:

1. You prepare differently for each color.

2. Your choice of openings as Black fits your playing style better than your choice as White.

3. You feel like you have to win as White, which creates some psychological pressure that negatively affects you. On the flip side, you play better as Black because you don’t have this pressure.

I’m curious: what openings do you play as White and as Black? I suspect that your choice of openings is the most likely reason for the disparity between the colors, but that’s just a guess and nothing more.

For example I got two completely winning positions against 2 experts as black in the carokann, but as white got into a huge mess in the leningrad dutch that I ended up losing (though I may have had a small advantage), and got a drawn position in the slav against experts.

And I think youre right hicetnunc in both regards, one reason why I need to figure out atleast 1 line to play as white in each opening.
