What's the secret to matching Condition?

What trick do I have to use to write a pattern that matches Condition? These don’t work:

MatchQ[Hold[a := b /; c], Hold[_ := _ /; _]]
MatchQ[Hold[b /; c], Hold[_ /; _]]
MatchQ[Hold[b /; c], HoldPattern[Hold[_ /; _]]]
MatchQ[Hold[b /; c], Verbatim[Hold[_ /; _]]]
2 
MatchQ[Hold[b /; c], Hold[Verbatim[Condition][_, _]]]
3

The first 2 don’t work because the Condition on the rhs is interpreted as a condition.

The third one doesn’t work because HoldPattern doesn’t prevent the interpretation of Condition, merely evaluations.

The last one doesn’t work because Verbatim means literally. So this also stops Blank[] from matching anything but a literal Blank[].

The following also works:

In[1]:= MatchQ[Hold[b /; c], Hold[_Condition]]
Out[1]= True
