So, what I'm trying to do here is to see the effectiveness of my cbetting.
I've tried to look through all the filters available, problem is that I can see all the stuff regarding MY actions, but I can't find anything regarding opponet's actions.
Is there a way that I can set up a filter to show when my opponenet has folded to my cbet? 
Are you trying to find how much a specific opponent is folding vs your flop cbets?
If you want to know the efficiency in your cbets in general there's a stat available in the report section: "Flop CBet Success %". This demonstrates how the opponents are responding to your Flop CBets. It determines how much your opponents are folding to your Flop Cbets. The higher the more effective you're making you're Flop CBets.
