This is actually a good question, and it's a principal reason many low level players hit a wall. Many people think that to "get better" they need to just calculate more moves across the entire board. This is time consuming and not practical. What they really need to do is learn the principles of chess and apply them to the board. This includes weak squares, piece activity (a big one), prophylaxis, control of the center, developing with tempi, etc. etc. If we were to analyze one of your games, many of the moves you would have played would violate those principals.
tl;dr Every time I make a move, I'm using logical reasoning based on chess principles (with some exceptions in the opening).
If anyone learning all of openings,middle-games,end-games. So when ppl will think urself? Its not thinking, just they calculate some moves others have already learned and u put em automatically like in a book.
