Ok guys.

So I've been doing a bit of work on CREV when it gets quite complicated when it comes to my bet-flop/check-turn range. Do I need to protect this range from exploitation so that if Villain was then to lead river I have a decent defend % or is this irrelevant as I will be barreling a decent % of turns anyways. Can somebody maybe give me some insight into how I should be constructing my bet flop check turn range and with what frequencies I should be defending rivers. I know people will think I need to defend the (1-a)% but I'm not sure if this is actually the case here. If it is, please provide the Math.

Thanks guys
