First I hit almost 1200 rating then start losing losing, going down and down, blunders after blunders now am about 900. Everybody is better than me, also the last of beginners beats me. I think should leave chess until next life
Maybe try and do daily games? They help you think and take time to think your next move, plus you get plenty of time to make a move, so you don’t have to worry about the time limit!
