can i become a GM in 30 days?

can i?

nope, well next to 0.000000000000000000000000000000000000000000000000000000000001 chance. unless you are an IM.

no that is the simple answer. 

unless there is divine intervention with plenty of hard work plus a slight error in schedualling and some extreme luck. is the long answer.

i am 1423 and if i play and learn chess 24 hours a day with no breaks, can i?

ummm no you'd die of dehydration

What's your highest FIDE rating and how many GM norms have you achieved?

i am not saying me, but anyone. my highest fide is 1423

if the question is "Can I die from sleep deprivation, exhaustion, and eventually total organ failure, yes!"

you have got to be kidding me. . . 1423 to GM in 30 days, wow

Yes, provided you count your fifth birthday as your first day where you get a proven grandmaster trainer retained as your coach and then don't count any more days until the 29 days prior to you getting your grandmaster title at the age of 29.

That is a tight schedule so maybe not in the next 30 days but in some specific 30 days perhaps. The task before you is to gain entry into at least 3 tournaments; earn a GM norm in each and get FIDE to announce your title by the end of the month.

If you have enough money. You could arrange tounaments for yourself and lay out lavish appearance fees  to invite top GMs to compete against you. Then you get FIDE to sanction these private tounaments. With enough money you could probably do that too. Now the hard part, get the norms. Remember though, the more you pay in appearance fees the less likely a GM can be bribed to take a dive. If you pay him enough upfront, he won't need your money when you go to rig the game. Then lastly, make sure the results get to FIDE in time.

my rating is 2139 can i become a gm

What do you think yourself?

Of course you can. May I suggest you keep training after that so you can beat Houdini 4 consistently? You will become the Great Grand Master!

it takes at least 10000 hours to become good at something.

2000 days at 5 hours each day.

66 months

5 years.

and another 10000 become better.

and another 10000 hours become even better.

and another 10000 hours

so I guess 40.000 hours of learning the correct things.

+ hours spent reading the Modern Chess Opening's Encyclopedia from cover to cover.3x.

It does not matter how much you study. ELO points are gained by playing rated games. You cannot even earn a National master's title in 30 days from 1423 elo by playing and winning everyday's rated game. 

define GM, if Grandmaster then no...

even if you were a greater prodigy than carlsen i doubt you will be able to get the 3 norms in 30 days

You can became crazy in 30 days

GM, No Stupid

30 days is not very long. Instead of asking, why not just try? You will have your answer in 30 days.

Yes, all it take is a little under the table money
