I myself was introduced to the world of chess by Seirawan's Winning Chess Tactics!
I think you should go for a nice split (although I'm not an expert!):
Solving puzzles and playing out master games is a good way to learn some of the most common ideas, such as opening principles, forks, skewers, etc. However, in my experience, playing games has exposed me to some of the tricks ad concepts that happen in games that are around my rating range.
Most of the six-move tactics featured in Seirawan's book probably won't happen in your games, but you will often discover simpler two-move tactics in your own games that the objectives in the puzzles and books helped you find.
I've been playing around 880 for around a month (learned how the pieces moved as a kid, never tried to seriously learn the game, but always enjoyed playing). Now at an age where I'd like an indoor interest as it were, and chess seemed like a good choice since I always enjoyed the occasions I played.
I've gotten myself Chess Tactics by Seirawan and I'm doing puzzles etc online as well as watching Twitch streams by GM Kosteniuk , Levy, GM Hikaru etc to pick up what I can there. I've also joined a few tournaments on the site for my level. I'm also intending to look into going to the local chess club when restrictions are lifted (provided they'll take a hopeless noob!).
Problem is, I reckon the sheer volume of the games from the tournaments is overwhelming me, leading to a lot more blunders than I generally make, although I do have the occasional good game here and there.
My main question is this;
Should I cut back on the volume of games (I tend to play daily) and concentrate more on the puzzles and books or carry on with the 'more I play the more I'll learn' mentality?
I'd appreciate any tips and advice from the good folks on here as I'd genuinely like to improve to a half decent level if I could.
Thanks in advance.
