If you are a budding chess player, religiously follow the games of the Super GMs from their Young age or formative years. Bobby fisher, Vishy, Garry, Wei Yi, Magnus, Ding etc.
Alternatively, You can follow the games of contemporaries across sections open/women.
One such example is here. Two prodigies playing. Rd8 by Bodhana’s opponent screams mistake. If you are 1700 Fide you can sense mistake with that move. It gives white the initiative. Seeing through the initiative, building pressure around the king and forcing defence onto the sequence 5-6 only moves is where 1700->2100 transition comes.
Do follow this game and analyse deeply.
Always remember Kasparov’s principle, Give your opponents 8 consecutive threats. On an average the opponent will make a mistake on their 9th move. It’s highly relatable in equal but sharp positions. Statistical chess is a thing.
