I think there is no real connections between time and winnings. It just a chance. I prefer night (at my local time) because then is the most players online where i play.
My favorite time for poker is the evening. Just because I can not play at other times of the day. And when I came after work, I ate, took time to my beloved family and after that you can already allocate a couple of hours for the game.
i think it doesn't matter what hour you play, you will find good and bad players at any time. i don't know if the percentages change, this will be a more in depth fact which needs research to be proved valid.
personally i play in the evening of european time just because at that time are most freerolls held.
I prefer to play in the afternoons ... after 1:00 p.m. ... because I take the mornings to attend to my personal things ... so I will not have pending tasks to attend during the time I am playing poker .... I have also noticed that from that hour start the tournaments with higher prizes ...
there is no connection between the time of the game and the win, I do not have certain preferences for the time of the game, I play when there is free time
I play in the morning, in the afternoon, in the evening, in the night. It does not matter when. I have a free work schedule. And the sleep mode is broken.
I like to play in the afternoon, because it's at that time that I wake up and so I'm more focused and sometimes I play during part of the dawn as well.
I like to play poker in the evening. Usually evening tournaments have large prize pool than the morning. The main thing is not to fall asleep during the game)
