My friend advised me to sleep before the tournament up to 2 hours
What do you think about it?)
I have not tried it yet ...
But perhaps it's true!
I think it's not that bad idea at all, but try not to miss the tournament sleeping too long!
It's always a better idea to play poker awake and having a good rest before, rather than being tired and sleepy. It's because in first case your brain can concentrate way much better, than in a second. Also i would recommend to plan your poker time well and calculate how many hours about will take your tournament, so that you not find yourself in a trap, where you actually supposed to be in bed, as you have to wake up early next morning, but currently you are running so good and just can't leave your game. It's not good at all and i made this mistake myself pretty often. Always choose to play only those MTTs for which one you have time without struggling not to fall asleep.
But have to add one more thing, don't play poker instantly after you wake up. Let your brain some time to get fully awake and concentrated. Drink your coffee/tee first and read some articles about poker or analyze some
poker hands you played before. Tune up yourself for
poker game first. It takes about 30-60 minutes, depends on how quickly you are become fully awake. This advice i've read myself in some poker book, unfortunately can't remember at which one.
