Guys help me simplify my opening repertoire 2000+ players please

I am looking to cut off my opening for black .....i have decided to play the Queen's gambit accepted for black and for white the Catalan against slav and against Indian defences i play the trompowsky....help me simplify it

Black icons have to arrest the white king.

King's Indian Defence, no matter what!

Just my immediate thoughts here ... it seems you like to open with 1.d4, which is great. In order to meet your 'simplifcation' requirement, I recommend going for strategically clear lines (the Trompowsky does not seem to mesh with that idea). If it suits your style, then specialize in Exchange variations: cxd5 versus the Queen's Gambits, including the Slav. Against 1...Nf6 & 2...e6 go for a Queen's Indian, and against 1...Nf6 & 2...g6 (or 2...c5) go with the fianchetto lines. Some of these openings will lead to symmetrical pawn structures, but it will give you a clear direction based on exploiting a small development advantage. It also allows you to gain a reasonable measure of control over the complexities the King's Indian Defense, Grunfeld, and Modern Benoni. This may add a lot more lines than you'd care to learn, but you will learn a lot about a variety of important structures in the opening & middlegame.

An alternative idea is to open with the Nimzovich Attack, 1.Nf3 & 2.b3. Most lines lead to book 'equality,' but this is not a drawish opening in my opinion, and gives you some clear strategic paths where you should be able to work out the the tactics without undue trouble.

At any rate, I hope this is some useful food for thought!

QGA is risky, as White can develop around the center faster. No no, you must choose something where you have _fun_ , like some sort of gambit like the Benko or even the Pterodactyl defense, which many players don't know this much.
