I was about 700 ELO then I got this course. I started to be aware of any Blunders ( I could find ) I fell down to about 300 ELO. I must have been blundering everywhere, my opponent too. Now I am much more solid and climbing past 500. Maybe this game is extra hard for me lol. I took an ELO test on Lischess? They said I am 840…. I am confused lol and frustrated. I don’t see checkmate patterns well. I started playing just to exercise the ole mind. Now I think I need to go work on Check Mating patterns….. I hope your chess Journey Is going well. Any advice Is always welcomed. Have a great day,,,,,,,,
