Thanks for the post, and for analysing that game, though I realise I played very badly in that particular game, I understand your explanations for the mistakes. And I do understand the difficulty of the game, if chess were easy we'd all be experts at it. And I wouldn't be here.
I did mention about blitz, since I'm aware it doesn't help. I play it more for fun than as a means to improve, though I'll try to play less in future and play more rapid.
Rant alert. Sorry if I come across as a whinger etc.
I've been a premium member on this site now for over a year, and in that time whilst I did take a break from chess for awhile (a few months, minus the odd few tactics and the odd game here and there), it doesn't feel like I'm improving. I can generally follow along with videos or tutorials, I know all the rules of chess, I know what forks, pins, skewers etc are, but often I feel like I'm just repeating the same mistakes over and over, and I often get annoyed with myself (and chess in general to some extent) when I lose, or get puzzles wrong etc.
I have and am seriously considering a coach, when I both find a good one and can afford it (6 months or so). However, for now (and possibly even with a coach), I'm not sure what I can do to improve or better yet stay motivated. Unfortunately I generally have a fairly negative view of things in general, and I'm often of the opinion that if I'm not improving or skilled at something then I'm kind of wasting my time and it becomes no longer fun. It's not that I have depression, but I often feel very upset after game losses or similar, it sounds ridiculous but a few lost games can ruin my day.
Also, for anyone looking at my profile. Yes I'm aware I play a fair amount of blitz and bullet. I know these aren't good for improvement. However, including multiple resets I've solved well over 4000 tactics, possibly 5000 by now. Whilst I enjoy them, they are often annoying when I get them wrong or whatever. I also play a lot of daily chess, and rapid when I'm in the mood for it. But in games, be it that my calculation skills are bad, or my strategy or whatever is bad, I blunder, or mess up, or go from winning to losing etc.
I'm rated around 1100 rapid, so I take that as an approximate skill level. To most this would put me in the novice/noob level, I like to call myself an average beginner, since as I said I understand all the rules and have played a fair bit (about 1000 games on this site so far), and can beat the average person on the street (probably). But I'm still pretty bad overall.
I see the beauty of chess, it's a beautiful, yet cruel game. It rewards the brilliant and punishes the weak. If you blunder it's your fault, not the luck of the dice or cards etc. I see the art of a beautiful fork, pin, or mate etc. I don't want to lose my interest in this game, but I do want to improve and not just lose any and all motivation for this great game. I'm 23, so I'm still young, but I hugely regret not playing more chess as a child when I could have absorbed more information than I'm able to now.
