I've been watching a lot of Seans video's and just finished watching a video James made about defending vs small 3bets. Definitely good material and I've learned a lot from them so far :)

I got one question that's been bugging me: let's say we want to find the optimal 4betting strategy after we open UTG and the Button 3bets us, do we have to take into account that the blinds also cover a part of the defense? I have been watching some video's and reading some stuff online, but it never came up.

I assume this is true, is there an easy way to take this into account? By that I mean come close to the true optimal range, because it's probably very tough to find the true range. Is it doable to find this range in CRev?
