Chess tactics

How is it? Last I practice a lot of tactics on different pages.
For chess / com my tactics has grown from 1500 in 1950 elo.
Why, despite the increase elo tactics, it seems to me that I play worse than before.
Maybe it's because I played a little chess live, and too much an exercise tactics?

The tactics trainer provides an opportunity to calculate a defined set of moves where there is either a forced mating sequence or a forced gain in material. It does not provide the practice required to develop positional strategies that are an essential part of chess games between humans. The tactics trainer demonstrates only a small part of the chess skills required. It is very important part of our chess skills but it represents the final phase of an attacking position. The strategic plans and positional maneuvering get's the player into a position where the opponent can do little to stop mate or material loss that should eventually result in mate provided the attacking player has the ability to skillfully use tactical calculation. If you can learn good chess strategy and have well developed tactical skills than results will flow from this. More easily said than done. (:

Well said, droceretik!

Opening plan (Read & learn about opening strategies. The aim is to create a pawn structure for the middle game. Every pawn structure has a strategy. So that pawn structure strategy is part of the middle game strategy.) Think about the 3 golden rules as you try to master the transposing opening puzzles. lichess.org/training/opening
Middle game is combinations (Master the tactical puzzles.)
Endgame is technic (Master simplified common end games.)

Once you master every phase, it will pretty well boil down to time to play.
Think about the 4 elements as you enjoy the game.
Ever move will affect 4 elements of your game:
1. Squares (Weak move because it was protecting a square before moving. After the move it is protecting other squares.)
2. Open lines (The move opens new lines and closes others)
3. Position (The piece that is moved maybe in a better or worse situation. Like landing on a safe or unsafe square and ends up with less or more mobility)
4. Center (Control it, occupy it and move pieces through it. Using the center is taking advantages of the chessboard.)

Chess tactics and calculation are a huge part of the game, but it can take a good while for an improvement in tactical puzzles to translate into an improvement in your general play. Below are a couple possible reasons I find to make sense:

1) Easier tactical puzzles can often give you the illusion that everything works and you're always winning, which isn't the case in a real game. Everyone misses tactics (possibly quite complicated ones at higher levels), but sometimes there are simply no tactics to be found, or the best thing to do is get a quiet position or slowly build up your initiative so that you eventually have an unstoppable attack with tactics falling from the sky. That "quick" solution of tactical puzzles often isn't there, and trying to force it can lead to blunders.

I do think tactical puzzles can still help with this, but you may need to eventually study slightly harder ones (keep on going, you seem to be well on your way!). While you're studying them, don't just pay attention to the winning line; pay attention to all the lines which you initially think might work that turn out not to work at all. It's important to not only build pattern recognition for winning tactics, but also pattern recognition for aggressive lines that do not work.

2) An increase in calculation ability is useless without an evaluation function. Tactics and calculation can help you be aware of more things and see deeper lines, but you still need to evaluate the position at the end of each line. This means you also need to be aware of a bunch of things in chess besides material and mate: initiative, pawn structure, king safety, piece activity, the value of each piece in a position, and the list goes on and on. Watching chess videos, chess commentary, or pretty much just listening to people talk about chess that know what they're doing have really helped me with this, though I still find myself going into lines sometimes which I think give me a big advantage, only to later find out that I let my opponent equalize or even gave the advantage to my opponent.

You're probably right about it being a good idea to play a bit more, but I also don't suggest giving up on puzzles if you really like them. Studying the parts of chess that you like keeps your interest up and in my opinion these puzzles do improve one very important aspect of your chess play, even if this doesn't yet translate into an improvement in overall strength.
