KK hand vs your friend
What are effective stacks?
I would open to $25 probably, esp EP. At least in my games, I'd say that's around the standard open. I'd also potentially 4b (pending stack sizes).
As played, really don't like the turn donk. Just c/c down. What hands are you hoping will continue on turn to your donk that would bet and then fold to a flop c/r or not keep betting themselves? I'd prefer c/c down > c/r flop+barrel > donk all streets > c/c flop and donk turn.
