Lock yourself up with an extremely good chesscomputer and play chess all days. Play tournaments all day, all weekends, always. Play chess, think chess, sleep chess and dream chess.
Refrain from all other things in life, except eating, drinking and sleeping. Ask your mother to feed you and finance your costs. And NOT bothering you with her feelings and sorrows.
That's the receipt Bobby Fischer would do now a days.In older times Bobby Fischer really followed this receipt except the computer, because the computer wasn't there in these older days.
And it worked for Bobby Fischer !!!!!!! Maybe for you too and are you able to make a win against Magnus after 12 or 15 years living and playing chess in this way. Because that's about the period Bobby Fischer needed living and playing chess this way all the time to become the world champion.
Do you feel invited ?????
I'm guessing even Yuri would be having some trouble against Magnus.
I suspect that you are correct, sir!
