I really wish to improve my chess skills a bit, albeit I am pretty sure that I do not want to become a grandmaster.
One of my problem is my king's safety. Chess is very different from some other board games. E.g. in checkers you must either kill or immobilize every single opponent's pieces in order to win; however, the rule of mandatory capture repulses me quite a lot from playing draughts. Chess is much nicer, it's more elegant and has much more possibilities. But having your queen, rooks, bishops, knights and pawns in good squares, a good attacking position and knowing strategy and tactics, openings and endgames etc. is nothing if you are so, so bad at providing safety for your king.
In fact, I would say I'm quite good in endgames where pieces are so few. If I have a pawn or a piece advantage and manage to get to the endgame, then I can make my way to a win. But my opponent rarely allows me to play so many moves. The game ends in the opening or middlegame. That is, I'd like to say I've studied fool's mate, scholar's mate and so on. I know how to avoid them. Most often, the opponent checkmates me in the middlegame.
I've seen a couple of great chess games on youtube. For example, 1851 "immortal game" (Anderssen–Kieseritzky) impressed me so much. And of course, using my chessboard I studied (played back) quite a bunch of other famous games played by very good chess players. Many of them seem to have the same theme: the stronger player constantly gives checks and thus blocks a good majority of squares around the opponent's king. Then, he/she delivers checkmate, using a great advantage from those blocked squares.
I am not sure if I should keep my own king open or closed. An open (bare) king seems to be a bad thing since it is very easily separated from my pieces and then driven to the edge of the board. But isn't a king surrounded by friendly pieces from different sides even worse? They are used as an advantage by the opponent. Moreover, I am often checkmated with a knight, so it can be a smothered checkmate.
Unfortunately, my search for "king safety" on this site did not provide too much useful information.
The question is if they are any videos or maybe sites or written material which would help me to improve my king's safety? Apart from very obvious advice, e.g. an early castling. Believe me, I know my castling well.
When playing chess, I still try to concentrate on capturing enemy pieces and thus to make my way to the endgame. I know it can be criticized but it's my style.
