Not in the evening, but that's when most of my games are, tired.
Just after midday probably.
When is your prime time?
Sort:
In the early evening.
Don't know. I only play at night. So I'd say from 12pm to 1am. I'm joking. From 6pm to 8pm.
Wow! How do you stay so sharp in the evening?
Practice. 
My prime time? 24 hours a day, 7 days a week.
Anytime when I have enough caffeine.
1:32 pm
probably 7pm
By "prime time", I mean the part of the day when your chess performance is at your best.
For me, it's between 3pm to 4pm.
What about yours?
