I understand that if we cbet 50% pot OTF then we need a Villain to fold more than 33% of the time for it to be +EV.

I understand that when calculating fold equity we need to consider what our Villain PF calling range is and the types of hands they are likely to continue with vs a 50% cbet OTF.

So we can use Flopzilla to calculate our fold equity.

However, this assumes we have 0% hand equity, (or does it?)

So how can you add your hand equity OTF vs their range into the equation?

Here's an example:

Villain is a Fish who calls PF with 100% of his range and calls a 50% cbet OTF with any slightly made hand which includes stuff like A high and Overs.

I hold AK

Flop: Q65

Our fold equity is calculated at 34.5%.

so purely considering fold equity EV cbet = 0

However our hand equity vs Villains range OTF is 50%, so how can we add this into the equation to calculate our EV and therefore how we should plan to proceed in this hand?
