Checking the lines, KK on BB

[Genz]

meh. It doesn't really matter. And it doesn't hurt to be consistent with your bet sizing so that people can't read if you are cbetting or value-betting. If that is your standard bet size it's ok. I always vary my bets a little so that I can bet more when I want value or good fold equity without giving my hand away. The flop play isn't bad.

Edit to add: it's 1BB more or less. And that can have an impact on your winrate on the long run. You want to extract the most with your winning hands.
