Nope.

Extensions extend a full width search, meaning after a check I extend on I look
at *all* continuations maybe one ply deeper.
Quiesce is limited to very few move types like captures and promotions for some.

By the way, fixing your program to find a mate fast in these positions is silly
since they will not happen in real games.
