Hi fellow members of chessmood. 
 

I have a question. I've decided a few months ago that my priority was to work on my endgames and positionnal play, because it seems it is my main weakness overall and the main way to get better on the long run. 
But looking at my recent stats, I noticed that most of my rating gains were due to wins with the black pieces. My weapons with the white pieces (I'm a d4 player, mainly Queen's Gambit Harrwitz Attack), wich have been reliable for years, seems a little bit shaky lately, maybe due to my level growing and meeting better prepared players. Its true on chess.com (around 90% win with the black pieces in the last weeks, only 50% with the white pieces) and in my last OTB tournament (2 out of 4 with the white pieces, 4 out of 5 with the black pieces, although one of them was lucky if I'm honest). 

At some point I will have to do something about that, either studying the openings I already play and look for what's wrong with them and fix it, or go for a new repertoire, and diversify my play, get new positions. I've had a look at the whitemood repertoire and I find it appealing. 
Normally I would wait for that. After all, I have already decided that working on engames was the priority. But I have a five round tournament next week (13-14-15 september), so I wonder if I should work on my white openings before it.  Also, my usual sparring partner will be there and she knows very well my weaknesses with the white pieces (so I expect to be crushed if we play against each other and I get white).

So
1. is it realistic to have an acceptable level of practice with the WhiteMood repertoire in one week? feels probably not, but maybe yes. 
2. should I just make minimal work on my actual openings and still work on my long term plan of prioritizing engames without making any exception?

I would like to hear advices on that so I can make my mind.
