I have a piece of advice and also a question. The question is what do you consider "long" specifically? As in how many hours? Curious as each person has different perceptions and expectations.
The advice is that when I play tournaments, sometimes I am expected to sit for 12-13 hours with a few breaks and one long meal break only. So what i have found is that i need to take my own breaks, stretch my legs, walk a bit. Maybe make an elongated BR break. Just to not feel like a zombie. This is specifically for Live trnys.
When playing Online, i feel the strain even more. The fatigue on the eyes is worse, the feeling that "you cant miss a hand" is even greater for some reason, since the whole poker universe fits.on one tiny screen, with access at yoj fingertips...literally.
So when i play Online, and i have been successfully stacking chips for some time, i will often leave the screen early before a scheduled break. Ill play my "free" hands wait till i get on the button and then get up with an extra 5 mins to just, BE.
To be one hundred percent honest the age olde adage, you cant win a trny in one hand, but you sure can lose it in one stands true to me.
In this perfect example: i got home at 1 am and played a trny online to "wind down" from work. I crushed the first 3 hours. Then i took a "nap" i.e. fell asleep for 75 minutes. When i awoke, i went from top 3 stack, to bottom 5. But we were only 14 players left.
I wound up winning that trny, and got over 3000% ROI. I am SURE the fact i had a little snooze in the middle of the trny refreshed me and had me feelkng refreshed, while my opponents were just counting the minutes till they were done.
