I enjoy this change in playstyle way more and I can't explain what it is?

I think I found my favorite way to play. Before I used to only focus on calculation, trading pieces, and attacking which would lead to a lot of mistakes. My common sense and intuition would tell me that something doesn't feel right but I would proceed regardless, thinking I could pull through with raw calculation.

I basically abandoned that approach and now I mostly focus on achieving the most visually appealing position for pieces such as control of the center, pawn structure, king safety, counterattacking. I'm fine with moving a bishop or rook one square for a better position whereas before I used to think it was pointless if it wasn't a part of some elaborate calculation. Now I don't have to calculate as deep and I have been having way more success and enjoyment as a result of playing this way.

How would this style be described in the chess world?

That sounds as if you might have added intuitive-positional thinking into your game. If you find yourself appreciating the games of Anatoly Karpov now rather more than you used to, I'm probably right (game 4 of the 1994 Karpov-Kamsky FIDE World Championship final comes to mind as one example). Otherwise, maybe I'm wrong.

If I'm right, the danger to watch out for is relying on what "looks right" at the expense of rational analysis of; for example; where your opponent's weaknesses are. Game 9 of the Spassky-Karpov World Championship candidates semi-final (Leningrad 1974) has several great moves which don't intuitively look all that good visually but which are rationally based on White having figured out that control of c4 and c5 (squares Black can't defend with a Pawn) is the key to the game.

Typing on my phone hence I've not added the games here, but they're both available on multiple websites.

I absolutely love his games, his style resonates with me most, it’s funny you mention him. I keep risks to a minimum and have a more reactive/counterattacking approach. I’d rather make small incremental improvements with each move and wait for the opponent to make a mistake.

@Rhtero1 Goodness me. Another Karpov fan! Likely because his play isn't really all that flashy (give or take Linares 1994 especially the sacrificial masterpiece that is Karpov-Topalov from that tournament) we're quite a rare breed.

At lower levels, chess is a matter of simple tactics. Players are calculating up to several moves deep.

At higher levels, chess is primarily positional. Players keep improving their position until a tactical opportunity becomes available.

I have written on several forums that the books that most helped me advance from 2150 to 2400 USCF OTB were Mednis’s book How Karpov Wins and then Karpov’s 4-book series on the Open, Semi-open, Closed, and Semi-closed Openings.

I hated Karpov’s style when I was rated below 2000. But I became a big fan of his at the master level.
