Improving your tactics would help a lot. Under 1000 tactic rating is not very good. No offense intended. A lot of amateur level games are decided by tactics because we make inaccurate moves leading to tactical opportunities, being able to recognize those opportunities will help you improve.
how to improve?

Case and point, just played two standard games. First game I totally miscalculated (imagine that) and then blundered in epic fashion after that. I swear I always do that first game of the day lol. Second game, my opponent played a move that's a well known blunder in the Sicilian dragon. I knew the tactic in that position so I crushed him. Tactics bro, tactics lol.
How can i improve my game further without any help from an pro coach? Any tips?
