This works only for c++17. Is there a way to convert this to c++14?

if (auto user = static_cast<CUser*>(pMover); user && !user->UserState())
        return;
c++14 c++17 c++

You have to split the if into 2 statements.
In order to limit the scope of user to the if statement, you can enclose it with {...}:

{
    auto user = static_cast<CUser*>(pMover);
    if (user && !user->UserState())
        return;
}

In this case, it's simple:

if (pMover && static_cast<CUser*>(pMover)->IsRecordBookOptIn()) return;

static_cast<CUser*>(pMover) is nullptr if and only if pMover is nullptr. And in that case, && doesn't evaluate the right-hand side.
