How to counter mid combo ROH flinch?

Let me clarify because I know that can sound confusing:

So I noticed that playing against 2H knights (only example I can think of atm) that if I get one hit going, and then combo into another hit (particularly an overhead) they can just crouch backwards and ROH flinch me while I was about to get another combo swing (second overhead) on them.

Ultimately I garb on these kids because they're typically gambler cavemen but this tactic feels dirty and I want to know how to prevent this.
