I dont belive your 1400 after 6 months
Why? I went from around 600 to 1400 in less time. Usually, those who improve fast at chess aren't necessarily more 'gifted', but mostly, they invest more 'time' to improve. I've spent countless hundred+ hours on Youtube, Lessons, Puzzles to learn as much as I can.
For me, so far, 600 to almost 2000 blitz in 2.5 years.
I'm not buying it 1400 in 6 months psh who's your coach magnus himself 🤔
