I am confused. What is the EV difference between a donk bet and a check raise? In which cases is it better to be donk betting and in which cases is it better to check raise?
This is an important question. It's discussed on many sites and forums. I don't want to copy-paste the text as it would be my own, so:
HERE you can find the summarized pros and cons of donkbet and check-raise.
And HERE are a good list of the situations when to use them.
To understand the second link, You must understand first polarization. You can find info HERE about it.
This really depends on many factors.
This is the thought process though:
-Fold equity difference between check raise & and donk bet.
-Line consistency with represented range(Do I want villain to call or fold? Which line best represents the range I want to represent for him to fold/for him to call?).
-Pot growth potential vs villain call frequency.
-What will I do if my donk bet gets raised?
