Hey reno, first off. Thanks for that in-depth analysis. Any chance you coach professionally? It's different playing games, studying tactics, revisiting games played by the masters, and studying openings and middlegames on your own, than to actually have someone look at your games and point out your weaknesses. Kudos to you, and let me tell you firsthand I appreciate the effort.
Yes, I do study a lot when I do not play, usually after a string of losses. Some losses I know I deserve, some I just know I did well but somehow lost tempo and/or material. Some are just plain stupid. But after studying, I find I need to play otherwise it's just a mental note of the lesson easily forgotten. But you're right maybe I play too much.
I do remember that game of mine you posted. My oh my did I hate that 25.Qxe5. I felt it could've ended differently without it. No matter how any puzzles I solve, sometimes I just lose step or drop the ball like on that occasion.
About the other game, thanks for the advice, with emphasis on the central pawn. It's just something I read about, but only after that look you did at my game was I able to grasp it fully. Next time I'll be on the lookout, since as you say, it's so common with strong players.
And oh, do you have an chess youtube channel? I find it fascinating sometimes watching stuff GJchess or MatoJelic posts. Very instructional for a novice like me.
